Open Differential "Brake Trick Lockers" Off-Road Test In SNOW | RAM 1500 4x4 Real World Testing
ฝัง
- เผยแพร่เมื่อ 12 ม.ค. 2021
- Today I'm doing some real world off-road testing on my RAM 1500 4x4 and Its Open Differentials in snow, specifically testing the "Brake Trick" or "Hydraulic Lockers" to see if these tricks or tactics actually work to help gain traction with an Open Differential. BUY A REAL LOCKER!
I've seen some videos online showing some jeeps overcoming obstacles when one wheel is off the ground (without a locker) by applying the brakes to help and even out the torque resistance on each wheel. I've also had a few fellas comment saying they have had success with using the brake pedal when they find themselves stuck with an open differential.
Open differentials are very nice on the pavement but when it comes to off-road situations they are troublesome. the main reason being that an open differential will always send power to the wheel with the least traction. Hardly ever equally delivering power to each wheel. So I was excited to see if apply some brake pressure or a lot could potentially get both wheels on the rear axle to spin at the same time. hence the term "Hydraulic Lockers".
I also see if the factory traction control does anything in a stuck situation just for good measure.
Lastly I try and apply to park brake which applied brake pressure to just the rear axle to see if that would get both wheels to lock up and spin at the same time. As you'll see all my tactics failed and my driver side wheel stayed stationary no matter what I did. and I eventually actually got myself stuck.
So it seems that there is no trick or gimmicks that can really help you when you are stuck in snow. the only real solution is to put a locking differential in your truck or at least a limited slip differential.
Hope you guys enjoyed the video and my shenanigans!

It should be against the law for truck manufacturers to build
One Tire Fryers . The wheel with
NO TRACTION is the one that spins , pure genius.
I'm sorry but how the fuck else is the technology supposed to work? You can lock 4LO in the F series by pull the knob out in the cabin, and turning the dials on the front tires from auto to lock, then when you give gas all 4 tires spin whether they should or not.
I love my old Chevy with Eaton locking rear end. I have had to use the actual 4wd very little because when I've started to slip, often times the locking rear end does the trick before I get to the point of needing to turn on 4wd.
Same results with a Truetrac in a Ranger
Do you have the automatic Detroit Locker in your Chevy or the E Locker that you can turn on and off in your truck
I have used the parking brake tick a couple times. it works. you have to keep your release handle pulled so you don't apply it too hard, then step on the parking brake and feather the pressure for the optimum spot. you will feel it grab. it takes a little finesse.
when in doubt, air down, flotation and foot print are your friend, i used to run open diffs now i run a lockright lunchbox locker in my jeep and an Eaton E-Trax in my pickup, but when running open diffs, reduce tire pressure, and reduce speed, flotation will get you out, even with open diffs, also if you are going out in snow, carry some cat litter and sand, throw a handfull of cat litter behind or in front of tires that are slipping, wait a couple of minutes, the litter will clump and make a surface like cement and you'll drive out fairly easily (if you don't have a heavy foot) great vid stay safe
There's a way to do it by installing line locks (used in drag racing). On rear wheel 2wd, install one line lock for the two front brakes, and one line lock for each rear brake (3 in total). If you're stuck with one wheel spinning like yours (right rear spinning), WITHOUT PRESSING THE BRAKE PEDAL, activate the front line lock, and the left rear line lock. Run the truck and get the right rear spinning. Start pressing the brake pedal and it will start clamping on the right rear brake. As it starts to clamp, the right wheel will slow/stop spinning, and the left wheel will start spinning....then you just have to feather it until you get unstuck. Since you didn't press the brake pedal when you activated the line locks, there's no pressure in those lines, so they are free to spin when you press the brake pedal. There's danger in doing that because now you only have one wheel with brakes. Once you're unstuck, deactivate the line locks and you'll instantly get all you're brakes back.
Or instead of 3 line locks, 1 locker or limited slip device.
Thanks for doing this thest. it proved my suspicion , that physics still aply. The only way i see it working with an open diff is if the side spinning coincidentally have a larger braking force in a lucky specific situation. An application with an open center diff it wil be a different story however regarding power front to rear
I had same problem. Bought a Jeep and haven't been stuck since. Love my Ram though. Yours is nice.
I got out of a real pickle last year. Got hopelessly stuck in a 3 foot drift in the middle of nowhere. After trying everything including a shovel, and as a last resort, I put my wife's coat under the passenger side rear tire. Climbed right out on the first attempt. It ruined the coat but my wife hardly had a mark on her. I left her there for the next guy to use.
Full of win 🏆!
There's a bit of a trick to getting Brake Trick to work. Step one: get your wheels spinning as slowly and evenly as possible. Step 2: apply parking brake slowly as you keep applying slightly more torque to the wheels, you should actually "feel" where you need to apply more.
The best trick, is to install a limited slip in at least the rear axle.
Yep you're correct
You install 4 seperate line locks on all for brake lines. Press the brake pedal, and line lock the wheels that are spinning/no traction, then take your foot off the brake, and the wheels with traction will go, then release the line locks once the truck moves.
1st time I've tried brake method I went up 25deg hill incline loose gravel and rocks with open diff. 1st try couldn't make it...after 1/4 hand brake and 1/4 pressure front brake...I glided up like it's not even there...just got to put enough gas and feel the flow. 96 GC 5.2 on 33.
@@521CIDI’m genuinely considering doing this. Could be good!
Long time Jeep off-road nut here learn from the benefit of my experience. Before the truck even leaves the lot you need to work out a deal to get some minimum BFG all-terrain tired. preferable a mud tire on your truck mud tires do really good in the snow you probably don't know that. Next up again before you leave the dealership have it installed or buy the truck with a limited slip in the rear end. Third make your way to 4 wheel parts or wherever you want to get it and get a selectable locker put in the front differential. Fourth if you can't afford the limited slip in the rear open differential make sure you get the locking front diff because with the front diff locked you got two wheel drive up front and then the third wheel in the back you'll be pretty good and you're driving characteristics will be just fine you'll never notice the difference so tires first are locking front diff second a good limited slip like a Detroit no spin something like that in the rear. And make sure you got recovery points front and rear they have to be good solid ones and you need to get a recovery rope the kind that stretch and then recoil and bring you out of being stuck that's what you need.
There is a front bias to those hydraulic brakes, parking/emergency brake trick always worked for me. You have to ease into the parking brake until you feel it working. Carry sand bags, or rock dust bags for weight over rear wheel wells, also if you get stuck you can pour the sand or rock dust under your wheel to get traction. Chains work great too.
"As You can see it hits my fender, really loved it" 🤣😂 looool
Fun video, thanks. I just got through the Buffalo blizzard. My F150 4x4 with open difs was buried in the driveway. With traction control on, I was stuck. With traction control off and a little rocking, the truck blasted through a giant snow drift and out into the street.
Being used to seeing a Mopar fail, usually my brother in law is driving.
👍 great videos, a shovel is a good thing to have, but a better thing to have is a cut off roof rake that you can position under your truck and pull the snow out. You could be in two feet of snow and dig your truck out with the cutoff roof rake in just a few minutes dragging the snow out from underneath it. Hope this tip helps you I've used it many times. I would like to see a video using a cut off roof rake getting you unstuck. ⛄⛄⛄
If you are overcentered that rake will be useless! Also , running boards suck in these circumstances.
This was a great video to show just how easy it is to get a big heavy truck stuck in not a lot of snow! Thanks for making this 👍
Also shows the importance of having some recovery gear with you.
The e brake trick works far better when in 4wd low. And like other people have mentioned when you have a hand e brake lever.
This video also shows that traction boards don’t do much unless you spend time getting them half under the wheel. But the one thing that makes all the difference is tire pressure. Drop all 4 tires to 15psi and the difference is night and day. But if you are already stuck it’s going to help. But probably not get you out. Every time I’m off road my tires are at 13 psi. And I don’t have beadlocks. But my Jeep xj is very light and on 33” tires. So it’s hard to pop a tire off the rim unless you go down below 10psi. Cheers
happy you liked the video! I really thought with me hard on the brakes I could spin both rear wheels but obviously it just didn't want to co-operate lol and yes If I was truly stuck I could of really made those traction boards work but I was just getting annoyed with them haha
@@TheGettyAdventures yeah I could see the video was not going as you had planned ha ha!
I find that when I do the e brake trick. It works better for me in my Jeep when in 4wd. Just like the brake pedal trick. As the front brakes on the truck help slow down wheel spin not just on the front wheels but the rear wheels as well because of the resistance transferred through the front drive shaft through the transfer case and then down the rear drive shaft.
Also the brake proportion valve probably hindered your ability to stop the rear wheels spinning, as a higher % of the braking power is sent to the front brakes vs the rear.
And because you were in 2wd those front brakes were doing nothing to slow down the driveshafts as they were not locked together through the transfer case. No matter how hard you push that pedal. On another note.
My Jeep xj used to have drum brakes on the back. (Terrible performance I might add ). When in 2wd on snow/ice. No matter how hard I braked. I could only get the front wheels to lock up when trying to stop. But if I put the Jeep in 4wd. And braked again at the same speed. On the exact same bit of snow/ice. All 4 wheels would lock up and the Jeep would stop in half the distance. That’s when I realized the front brakes were stoping the rear driveshaft from turning as-well as the front.
I had a VW Golf 3 many years ago. Once I had to get it on a really narrow ramp. One of the front wheels fell off the ramp. I knew how differentials worked so without knowing this trick I tried pushing the brake and giving it some gas. The wheel which was still on the ramp and had traction started turning and I managed to get the other on the ramp as well. So, for me, it really did work.
its interesting because so many people swear by it but I just couldn't get it to lock up. when the snow starts falling again I'll have to give her another go.
@@TheGettyAdventures a front wheel drive vehicle, the cv joints and the friction from the joint act like a limited slip system, just a bit. I'f a wheel is in a rut in extension, the CV joint is further extended and bent, so it creates even more friction. So yes it will give a bit more power to the other wheel. Although by no means is it a locker. But I had an 88 Honda ac cord that was a great rally car. 😅 If I kept the tires out of ruts it would outclimb dedicated big wheel 4x4 trucks. No joke. On account if being light and front wheel drive. And the CV joints create a limited slip system.
The emergency brake does work. There's a few techniques you need to do with it. Only use your emergency brake. Apply very little. Applying your regular brakes locks the front tires.
Now, take the shovel and put snow in the back of the truck. Drop your tire pressure down to 20-25 Psi. This spreads the tread out on the surface and greatly increases your traction.
Always wondered if the brake trick actually works. Thank you for real-world testing.
every situation is different. But I couldn't get it to work lol
@Timms MC great comment! if you could actively apply brake pressure to one specific wheel that would be pretty cool. it's what traction control is supposed to do lol
I've seen videos of jeeps using the brake pedal while in 4x4 and having success. so maybe applying the brake while in 4x4 could be an option. I think the real answer is that you would want a locker of some kind.
Someone may have mentioned this, but did you notice all 4 wheels spinning the same speed in 4wd? This is likely because the vehicle is doing the braking by itself.
Ram (and many other manufacturers) use the ABS system to apply the brakes to the wheels without traction. This transfers power to the wheels with traction. Jeep calls theirs BLD (brake lock differential), Toyota calls it ATRAC (Active TRAction Control), Nissan calls it ABLS (Active Brake Limited Slip), plenty of others use it as well.
Everyone brings up Jeep and Toyota but not Land Rover?? They are the pioneers of REAL working TC. My old Discovery 2 traction control from the late 90s that works way better. I can go out in my old Discovery and immediately with wheelspin it grabs the brakes of only that wheel not all the brakes, not one axle but only that we owe and boom pops me right out I don't get why no one can copy this old ABS wabco system is so simple and works so good Land Rover is the shit. If you see an old solid-axle discovery that look crappy nine times out of ten it's probably a champion off but people are just scared to work on them and they're really not hard. And old GM V8 and solid front rear axles multi-link suspension coils all around. Rock Solid
@@ronaldrrootiii6040 Land Rover was certainly a pioneer with these systems. The reason I brought up Jeep is because I know they share technology with Ram. The Discovery 2 is a great vehicle with incredible off-road capability, I was considering them when I found a great deal on my Cherokee and went that route instead.
Time for lockers!
Emergency/parking brake got me out of a tight spot on a 97 jeep cherokee. From my understanding, it mainly works when you have a hand lever because you can apply pressure on and off quickly.
Very true, the foot pedal is hard to just switch on and off like you could with a hand lever.
I usually just wait until Spring. Works every time
I didn't read all the comments so maybe this was already addressed but the brake trick only works on Limited Slip Diffs. The Brake Trick is really meant for when one wheel is off the ground where LSD's don't work at all. When you apply the brake it allows the LSD to use it's clutches or gears to start transferring power to the wheel with less traction. So the Brake Trick 100% works but only on an LSD. Jeeps do this all the time when they don't have lockers.
I suppose this is helping the system to work but should not be necessary so LSD is like a clutch that is applied when the core is hot. And the more one side is spinning and the other not, more heat is created due to liquid friction on the core. Maybe if the clutch is bad, breaking the wheel spinning helps the clutch to send more torque to the other wheel. But I had a car with LSD differential, and in snow conditions, I never had to break to the LSD to "lock"
@@borjaevo He's confusing LSD with a Torsen diff.
@@martinsv9183 I think you are right. Using a Torsen diff the car will not move if a wheel is in the air or has not traction at all so breaking could help.
@@borjaevo some torsen diffs have a bias built in, so in the event of a wheel in the air, it's still transferring some power to the wheel with grip.
@@blackgreyhound Electronic lock I suppose
That drive in the beginning was just like my ride from the grocery store to my house.
Brake trick worked in my 88 & 89 wranglers.
Both were open differential
Traction control doesn't apply brake pressure. It cuts power until traction is established
Love the channel man keep up the good work thanks for the replay I'll forever watch your channel.
Happy you like it! gonna try and keep the truck content coming
Great video. Really appreciate the real world testing
I’ve got a 2wd, 2006 Silverado, and I live in NY. It has a open diff, but if I give it a few beans both wheels turn. I never drive it in the snow, but I do have to move it around to clear the driveway of snow. I don’t know why that works, but it does.
Only works on limited slip diff. Never go offroad without a long handle shovel. Also dropping the tyre pressure makes a massive difference.
What kind of tires are you using? Also, keep in mind to let air out of your tires! A lot of air. They will give you more surface area...then just fill the tires back up to specs. Good Day
Great test but I had the exact same truck. I liked how much power it had, the ride quality, and all the extra features. When I decided I wanted something more “off-road” worthy I did tons of research and made my decision with a 2014 Jeep Wrangler JK. I traded in my truck and got it about 6 years ago now and it’s the best 4x4 I have ever owned. Yes I could have bought an off-road ram but I wanted something that was easy enough to work on, parts are relatively cheap to replace, and dependable as a daily driver. The Jeep checked all those boxes. My Jeep is the “sport” it does not have power windows or locks. It is the basic model is it gets but that’s what I wanted. I had an old model truck that had crank windows and it worked in frozen weather just fine, my other one had the motor go just a few years of owning it. Also the locking mechanism always got stuck on me for the rear doors. My Jeep now is not stock anymore but as I mentioned before parts for them are fairly inexpensive and as parts wear out I began to replace them with upgraded aftermarket ones. Today my Jeep has a 3in coil lift, Core4x4 complete adjustable control arms and track bars, 1 ton steering drag link, 1 ton inner and outer tie rod ends, and bilstein shocks. I currently have 33 x12.5 nitto ridge grapplers on it, body armor, front and rear steel bumpers, and a wench. It is a great little machine it always got me home in any weather and it brought me to a lot of interesting places. I to have open diffs front and rear and it always seemed to get me out of some pretty nasty stuff. The jeeps traction control system is pretty advanced as well it has the ability to apply the breaks to the tire that’s slipping to gain more traction I was very shocked the truck didn’t work! Either way I think it would be a good comparison my Jeep vs your truck on an off road adventure!
Can you install lockers on a jeep if you don't have them.
@@Sami-rp7mf yes you can but it’s very expensive and to have it done right. I found with the right tire size and driving time off road the Jeep performs well enough for my needs. Some people that are serious about going off road and want more of a traction aid they will install lockers or get the rubicon edition that comes factory with them. It all depends on what your needs are and budget
Yes to terrible open differentials! Great video. Thanks.
This is why I ordered my 2021 JLU with a limited slip rear axle. It makes a huge difference in the snow and wet roads.
makes such a big difference! especially in the snow
@@TheGettyAdventures There are times that I don't have to use 4WD because of the limited slip.
Open diffs.. yea not great
Clutched limited slip (Trac-loc) is the best way really if your using it in winter My TJ has this and it works far better than the limited slip on my ranger which is also decent/ok.
I can basically 2wd in snow most of the time on my TJ. The problem with Clutched is they do wear out eventually but Trac-loc's are good overall for most things.
Locked diffs are nice and all but on winter roads they can be kind of scary at times .. Air lockers / E-lockers are the dream but cost lots.
A couple more tricks I use, while in one case don’t use is your traction control in deep snow it will actually get you stuck by putting on the brakes and bogging you down. But every vehicles trac control work some what different. Rubber tie down straps if you get them so they go around the tire then hook to themselves through the rims slot can get you out of alot of situations. But once your out take them off they wont last long on pavement. Heard zip ties can work also.
I was going to try zip ties! I know the Toyota trucks have a pretty awesome traction control set-up that actually acts like a locker and will full brake the spinning wheel. I forget what it's called but I've seen videos and it seems to work very well.
@@TheGettyAdventures thats there creep control it works in sand. I don’t know if it works in deep snow. I love Toyota’s. But I had a sequoia and I got almost stuck twice in deep snow because of its traction control. You could not shut the traction control off. As I sat there stuck mad about the traction control not shutting off. I found out if you put it in low lock and put it down in first gear only, will shut it off completely. Then I was able to get out. It had been in low range. But in drive gear.
@@rnr5445 the creep control is awesome! Now I'm not sure if that is purely software based or if there is some actual mechanical components. but my guess is software based the and ECM is programed to controls wheel speed very finely.
@@TheGettyAdventures A-TRAC does not work that well. If I get stuck in my Tundra like you in your RAM, I get stuck the same way. The only low speed traction control that pretends it works is TRACS in old (2000s) Volvo. This thing keeps you moving until completely high-centered. But again, any truck will have no problem passing that high centered Volvo simply because of a higher ground clearance ;)
I ended up getting a winch, and planning to replace the rear diff with e-locker.
Wiggling your front tires back and forth while gassing it will typically help get you out when stuck. As well as putting those traction boards behind your wheels instead of the front and backing up would increase your chances of getting out. Just some trucks from a Mainer with a truck 😁
I guess I was kind of hell bent on coming out forward eh. Probably would of had some better luck coming out backwards like you pointed out lol
You're a Mainiac.
Wait? What are you saying to do if you are stuck? I’m from Maine also.
Loving your videos. I've had my truck for 3 years and didn't know any of the stuff you have shared about the 4wd system.
appreciate it Glenn! thank you!
@@TheGettyAdventures Hey, have you looked into the clutch locking kit for these trucks? Since watching your videos I found out about them in some of the forums I'm in. th-cam.com/video/ZWg6PND2otw/w-d-xo.html
I met the guy who makes these through the forums if you're interested. I'm going to review it once I get it installed.
@@GlennPearsonDIY Ya I have looked at potentially installing one. Seems like a great idea! It would be a cool video do some comparisons
Great video. May be should go take that drive now to Ice Road. You'll get 10k very quickly. Keep it up.
Thanks Brother. Good illustration.
Small correction: Traction control varies the throttle input. Stability control varies the brakes individually to keep the vehicle on course to the steering wheel position. Stability control works best when more throttle is applied in most situations. Traction control should be disabled in low traction situations where becoming stuck is a possibility.
Holding the traction control button will disable stability control.
That varies by vehicle traction control can use the same things stability control does. Agreed traction control will get you stuck especially on newer cars. It will often pull back enough power and brakes (on some vehicles) as well to cause a moving vehicle to lose momentum and stuck.
Loved the video.
Test 3 when you put on all brakes, is just gonna make it impossible to go anywhere. I mean you can be on dry asphalt, put on the brakes, and the front wheels drag are gonna make it impossible to move. Yes you did it just as a test, but in a real world stuck situation, just no.
Test 4 you may have had something, even if you couldn't "see" the results.
If you have 1 ft pound of traction/resistance on that right tire, the left tire will get EQUAL amounts of torque in an open differential. So you were sending 1 ft pound to the non spinning wheel, but with all the traction it had, it likely would not have spun until you had 10-15 ft pounds (not gonna happen in an open diff)
However, once you put the e-brake on (assuming it just brakes the rear wheels like most older cars) then lets say you had 10 ft pounds of resistance now on the right tire. Yes it will spin, but it will now send 10ft pounds over to the other tire. It may not have spun, but it could have been the push needed to get you out (assuming you could have got out with limited slip and didnt need 4wd) even though you didnt see the tire over there spin.
Open diffs suck, thats why my cell phone cover is a tag plat that says "1wheeldr", and i hope to rememdy that situation soon.
And dont get me started on the bw 44-44, which you are learning about yourself from the videos i see you post.
Keep up the videos, hope you make it to the ice roads. I just subscribed!
Great explanation, thanks for sharing!
Nice little rule thumb 👍 is if your going to play in snow ❄️ you will have too pop on softer tires on front that's made for snow, these all season tires are not Really for Snow. Why front truck heavier than back is. If want little stiffer tire on back for weight than get it better snow tire that's got different ply but tread really close to front soft tires, then you will be good in Snow only. They do wear out on dry roads in summer warning ⚠️
4 wheel drive on these vehicles are actually 2 wheel drive. Limited slip differentials are crucial for off roading. Even better, lockers front and back are best like on my rubicon.
100% correct sir! I would kill for a set of front and rear lockers. It would make a world of difference. although I don't even know if you can buy lockers for these front diff's.
Yes. The shovel helps. The shovel + maxtrax
You dug yourself some nice wheel chocks with those street tires.
Sometimes if you really mash the throttle and bang into 2nd or 3rd gear the side gear pressure is so great that it forces the other side to spin.
I’ve been stuck and pissed before and it’s worked in a pinch. Definitely running a risk of completely blowing up the diff though when you start banging gears spinning 😂
Also gotten un stuck by doing a massive burnout and melting through the ice while slowly creeping forward… hahaha
You drive an older f series truck, this generation of F series makes it too easy with this magical drive mode button to select these incredibly useful things called "drive modes" you can just put the truck into "deep snow" mode, turn traction control off, and lock the rear wheels, you don't even need to use 4×4 to save yourself in every situation. But a real man's truck doesn't have traction control
This is normal man behavior you describe
Open diffs can be manipulated manually by individual hand brakes for each wheel. Just like the Subaru X-Mode button and trail crawl mode, you can lock up the front tire on a turn and walk it around. But a locker in the rear is a must to increase your chances for traction.
I coulda swore you had more subscribers! You'll get to 10k I'm sure
thank you and that's the plan! hoping just keep making cool videos.
@@TheGettyAdventures Your makin great stuff now! I really enjoy it!
This comment aged well.
Rear diff lock in a two wheel drive truck gets you anywhere a 4x4 goes. Put on tire chains and you can pretty much do what you want.
Alot of people are mentioning the parking brake but applying some pressure to the brake pedal does the same. Newer trucks like my ford has a switch that engages the parking brake.
Thanks for trying this
I don’t understand why all manufacturers don’t offer a mechanical rear locker like GM does with the Eaton g80. I’m not an “off roader” but a lot of my hobbies take me off road and the g80 is excellent for situations where you weren’t expecting to get stuck because it kicks in automatically unlike electric lockers. It’s pretty much the reason I stay with GM. I had a 2500 Ram with the limited slip and it was just as garbage as what we see in this video. It would just send enough power to rock the truck a bit. When I bought my Sierra the Eaton was like a $300 upgrade… Unlike all other manufacturers where you have to buy their top model truck for $1000’s more to get any kind of locker (ie rebel, TRX, power wagon, raptor, TRD, pro 4x, etc).
The irony of this video is too darn good 😂
You showed a little personality in this video. Thumbs up 👍
Change your brake fluid mate. And make sure your remove any air from your system!
Have a jeep commander quadra trac II and works like it should. I could not do any off road before
Found with a smaller Toyota they tend to not get hund up as quickly as a full size truck when both were stock . The snow went around the Toyota we have as the full size truck the snow builds up underneath rather quickly and you get hung up alot more frequently
The hand break trick works on 4x4 with open central differential when rear wheel are spinning. But so you can't control which side are you breaking more is difficult for the trick to work for the same axis. This is what traction control does, breaking only the side is spinning.
Best setup I've had so far for snow is (aside from factory selectable lockers) Truetrac in the back, e-locker in the front. Best of both worlds.
Lockers in the snow can get you in trouble, so it's best to roll without them engaged as much as you can.
The "brake trick" is a real thing, and is intended to artificially compress the clutch packs of a traditional limited slip differential. It does kind of work in a pinch.
A helical lsd, like a Truetrac, has a much more positive engagement than a traditional clutch actuated lsd, but like a traditional lsd only locks up going forward; not in reverse.
An open differential, unfortunately, is what it is. Learn more about diff's and you'll get why.
The best thing you could hope to do without a recovery vehicle is dig it out and use traction boards.
Nice shovel ; )
Limited slip/ open differential ❓ sucks, I never could figure out WHY THEY CALL THOSE 4X4 WHEN ONLY TWO WHEELS WORK
I guess if the open diff always sends power to the wheel with least resistance, then with equal braking on each of the wheels, the wheel in the air still has less resistance.
potentially, lol I'm not 100% on the actual science but that's kind of what seemed to be the case.
Those GM watchmaker limited slips were not great because you were already stuck before the second rear wheel locked. You need a true locking diff that drives both wheels equally
Why doesn't Traction Control manage to apply decent brake pressure? Is your ABS pump ok?
Again awesome video!! Thought my 2020 had an LSD but was wrong lol so for $1200 it's getting one :) keep these videos coming!!
an LSD is so nice to have. I mean a true locking differential is obviously the best option but for most situations a LSD is going to be more then enough. Look into a torsen LSD, I've got one coming for this truck. no clutches to worry about just solid worn gears. Very cool units.
Same here. Re gearing my 2016 from 3.21 to 3.92. Throwing in a Detroit TruTrac LSD while I’m at it. No clutches, no worries
@@thecheekof awesome set up. especially with getting rid of those sluggish 3.21 gears. One thing to consider is if you are changing out the rear end gears. you'll also have to change the front diff out for a whole new unit which kind of sucks but my buddy has 3.92 gears and it really adds some get up and go to the truck.
@@TheGettyAdventures yeah I have been looking for a new front carrier assembly on eBay and other used part sellers. Nothing catching my eye yet. It is going to cost me about $3500 when all said and done for parts, labor,etc but it’s worth it to me because my truck is paid off. No sense in getting a new truck just for 3.92s like some others on the forums have recommended
Chains are pretty good
Another caution when stuck with open differentials is if your speedo says 60 your one wheel will be spinning at 120
haha and those spider gears are about to weld themselves together
Years ago got stuck out in the bush in my old 2wd truck. Used the floor mat and bottle of water trick. Worked like a charm. Lol
floor mat and water bottle trick eh how did you string that together ?
@@TheGettyAdventures Similar to the attempt you made with the track from CT. Dig out the drive wheel a bit. Make sure the snow in front is packed down. Lightly wet the carpet side of the floor mat and place it face down on the snow wedged under the tire. Let it sit and freeze. The plastic/rubber knobby bottom of the mat provides the tire with good grip. It's and old bush emergency trick. I've done it and it works.
@@jakemason9436 woow I like that. pretty much a DIY traction pad.
I've never understood why 4wd and especially 2wd trucks don't come with rear diff lockers. My 05 Nissan frontier has a rear diff lock...I wish the s10, hardbody and rangers I owned in Maine, which were all 2wd, had diff lockers.
Same bother! My nissan titan has a dedicated electronic rear locker that I can use when I have my truck in 4Low. While most these bigger brands just say it's 4wd without even having a LSD in the rear.
You can install your own. It's a simple job.
I'll never understood why switching to low gear in snow should work. If you don't have any grip, how should more torque help you out in this situation?
The first trick I learned for snowy roads condition was to shift up to reduce torque.
Nevertheless thanks for sharing!
Absolutely. My diesel has enough torque to spin in any situation. Low range is a sure failure.
I've done this many times over the years with silverado buried for up to an hour drives right out with some brakes
I thought the #1 tool was the brain then e lockers then a shovel. Great video.
An open differential always provides an equal amount of torque to both axle shafts, regardless of the speed of rotation of each wheel. The only way that applying the brake will increase traction is if for some reason the braking force is greater on the side with the lower traction. (A farm tractor with individual wheel brakes is a good example of when this can happen. Traction control will also do this.) If the braking force from the pedal is equal on both wheels, which ideally it always would be, then physics would say that there will be no net gain in traction by using this technique. Now if the vehicle had a limited slip differential it's a different story - braking force can help the clutch pack tighten up and apply more torque to one side or the other.
Maybe add an ARB air locker, or E locker. On my other trucks i've had a Detroit locker installed, i now drive a jeep gladiator rubicon - it has all the good stuff.
My 2020 Ram classic has the anti-spin rear axle. Should apply brake pressure to the spinning wheel only. I think it is better that way because you don't have clutches slowly wearing out in the diff.
i subscribed..i like your honesty....hope you get your subscribe goal...your brake trick will work on the limited slip diff...but not on open...keep at it bro. I used to own a 1980 chev 4x4 , 1/2ton, posi back limited front., 83' toyota 4x4, 97' chev 4x4, 2002 chev S-10 ZR2 4x4, and now have a 2006 Toyota TRD 4x4 ....always interested in anything with 4wd pickups...💯👊😎
when you put it in 4wheel low, and press the trac button it's actually still on, put it in 4wheel low and press and hold the trac button, you'll see it come up on the dash track control off, it will actually say it on the dash not just the light, it will give you full 4wheel drive but only up to about 15mph then it will come back on, just a little trick when you're really stuck!! It actually would've worked for you in this scenario!
I would also try lowering the tire pressure to 15 pounds, and use the wider footprint to help you get traction
Lower tire pressure is the opposite of what you want in winter - unless you're in big time powder and need floatation.
You want to increase PSI on hard pack and ice because it increases the PSI of your contact patch.
@@evictioncarpentry2628 not. Simple physics says you are wrong.
@@evictioncarpentry2628 you should stick to carpentry
@@evictioncarpentry2628 high psi onn the contact patch would help nothing, creating a wider footprint to get better traction is what you need.
Like a trials bike tire, grips and bites anything
Get this though, I have a 2020 with an open diff. If I do a burnout (without brake application) i leave 2 black skid marks.
I read somewhere that the brakes will automatically brake the wheel with the least resistance.
please try the "back-and-forth" method. that is usually all it takes.
People are probably talking about brake lock differential which is on many 4x4s who has open diffs as well as a LSD which is slightly different. BLD only works in 4HI or 4LO. It does not work in 2WD. Think of it like a poor man locker. YOu have to put in in 4HI or 4Lo and then apply the brake and the gas at same time. It will sound like ABS when it is working. Then move front steering back and forth at same time if you are truly stuck at the same time.
It looked like you got yourself stuck in 4wd. Then tried all of the tricks. For the purpose of this demonstration, it might have been a little more strategic to get stuck in 2wd. Then you'd have the front to help you get out. Great demonstration of the struggles off actually getting stuck and trying to get out. I've been through all of that myself with a 2wd powerstroke with open differential and 6 speed manual. It gave a ridiculous amount of torque to 1 wheel. Got stuck often. Even on wet grass.
I think the reason the braking trucks didn't work was because 1 wheel was already easier to spin than the other. If you applied brakes evenly to each, the same wheel was still easier to spin and you're still stuck in the same situation but with brakes on.
You also get more stuck as you try to get unstuck because the wheel spin melts snow and wetter snow is much more slippery than the original snow you got stuck on.
I use ballast weight and carry some sand in a covered 5 gallon bucket.
Great video.
Good advice. Simple rules the day every time. A scoop shovel in hand helps too.
Hi,in 4wd you should hold the brake,rawe the engine hold it an relasd the brake,kind of lunch
Rock it barb!!
My 2017 Ram, is currently a forward-only truck right now. Because of the open diff. Got er hung up on clay, cause it gave way as I was driving along the service road for the hydrolines. Had to leave the truck there over night. Took 3 tow attempts: 1) 2x 1000cc Polaris bikes...failed. 2) 2015 Ram 2500 (done to the tits)...failed. 3) 2010 Case backhoe...success.
But blew reverse in the process. But because of it, I now have ALL KINDS of shovels, winch and accessories in my tool box. Because never again will I get stuck like that.
Good vid
imagine that. A good ol fashioned shovel saves the day.
hey, with my samurai, i managed to get the other wheel to turn! just rev to cutoff and jerk the hand brake really fast,
actually DON'Tdo that with a Dodge lol
make me think tho... for off road purpose, would be great to have independent e brake on each wheel... so you could literally lock the spinning wheel! i guess thats what traction control is...
Always wondered if this worked. Glad my 1500 has a LSD
ya an LSD makes a world of difference. one of things I really wished I had
@@TheGettyAdventures I got lucky with it. I didnt personally option the truck out
What size rears you have and how you know what diff you have does it say it on the door just got mine with 3.92 rears 6 speed not sure
@@WHITETAIL215 on the front diff it will have a tag with the ratio and I did a vid decoder to find out about the LSD
@@TheGettyAdventures You could always install, or have installed, an aftermarket locker. There are a lot of choices out there that work well for turning an open diff into, effectively, limited slip. You can even do it front and rear if you want.
Shovel for the win.
The brake trick works to turn a limited slip differential into a fully locked one. It doesn't work with open diffs.
I had heard about applying brakes to get both wheels to turn, but I never got it to work at all. But then I watched some videos about the Torsen differential. And applying brake does equalize the torque. Military vehicles used the Torsen. So that is probably were the myth comes from.
It’s not a myth, it’s just really hard to do it. You have to get the brake pressure exactly right which is really tricky becuase it’s different in every situation:
too little brake pressure and you won’t slow the spinning wheel, and so no torque will be transferred to the stationary wheel;
Too much pressure and you’ll just stop all the wheels from turning.
There is a very fine line between too little and too much.
Balancing the throttle wit this fine line is also part of the equation, so yeah it’s not a myth, but it’s actually really difficult to make it work.
“Mashing the brake pedal” as he did in this video, is definitely not the way to do it.
Excellent...great real world experience
thank you, love trying stuff out like this
Use your shovel to fill the box with snow and thus put some weight on the drive wheels. Otherwise forgettabout it.
Just get a heat ray and attach it to the front angled down at 45 degrees
Hi there Alex, while I am nowhere near in the extreme conditions you are, I recommend for you install TruTrac diffs from and rear as budget allows. I have a 2005 GMC Sierra bare bones 2wd and can go in some pretty shaky deep sand and jeep 2 track roads. Also as you are aware a good set of snow chains can help as well.
the TruTrac diff's are awesome. I'm really hoping to get one in the future
Could that replace to original diff? Sorry if stupid question.
Have Detroit trutrac in my ram and works amazingly well. No clutch packs locks very good when torque applied to ring gear to drive both wheels
@@Brian-cf7dc yes
@@Racinls1 Truetracs are awesome. The best LS in imo. But since I installed a Detroit Locker in the rear of one of ambulances, I'll never go back to a rear Truetrac. Love the locker that much. The newer designs aren't nearly as obnoxious. I'll definitely run a Truetrac in the front all day. Also a selectable locker in front would be nice if you can afford one.
Don't laugh my 88 Jeep Cherokee with two open differentials and mud tires will run circles around your truck. The tires are the absolute most important thing you need to buy.
My understanding is the brake trick can work but the gimmick is that you need to pump the brakes on and off, on and off, on and off, while giving it continuous gas. You won't get much out of it, but sometimes the little bit you'll get will be just enough to get you unstuck.
All of my gm trucks/ suv’s have a G80 rear locker, hardly ever have to use 4WD.
got a Rebel, and snow tires. Make a huge difference.
That Limited slip differential makes all the difference.
I’ve used brake pressure and it takes almost flooring it. it will move all wheels.
In this case, he could air down to 5 psi and get out to. Or better tires to prevent it.
