- Have you ever wondered if there is. a real practical difference between the 4x4 systems in the Jeep Grand Cherokee (WK2)? In this video we take you out off road to the trails to see both the Quadra-Trac 2 and the Quadra Drive 2 systems in action, Off Road. Also, If you are wondering which system is in your Jeep Grand Cherokee, we show you just how you can tell.

Man. Nicely done. There is a handful of people who care enough to put the time in to explain the intricacies of jeeps systems. For real, well done bro
Thanks!
This clear explanation of the distinction between Quadra-Drive II and Quadra-Trac II is very effectively illustrated with the video footage of the systems in action. Anyone going offroad in muddy conditions will do well to watch this lesson and thereby avoid getting stuck.
Top shelf info that needed to be explained! Looks like it's best to get a QD2 system on a GC. Glad I saw you video and thanks for producing and sharing your video! Great job too!
Ausie videos of wk2 had same clicking. I think they indicated it was the transfer case chain jumping and slipping. QD2 has limited slip rear differential using clutch plates, not a true locker. Looking at the diff cover, if you see cooling fins, then it has QD2 ELSD. QT2 has a smooth diff cover. I’ve had both and it’s definitely better with QD2 in more extreme terrain.
I'm new to all of this. Very informative here man. I just got my mom's mint condition 2017 Overland with 11k miles. She passed from cancer and loved the vehicle. I love it too!
Great video comparing these two systems. It's really a shame that Jeep has made it basically impossible to get the quadra-drive II on a Grand Cherokee now. It seems like they never actually produced any in 22' with the Off-Road Group due to parts shortages, and in 23' now you can't get the off-road group on anything but the 4xe Grand Cherokee.
Very pedantic and interesting functional comparison of these systems. I didn't know anything about the difference when I bought my QD-II JEEP GC. I just know it handles like a dream on rough terrain. I got lucky! Thanks for the education.
Jeep had both systems available with the air suspension early in production, you could even get a V8 in a Laredo trim back in 2011-13. So you could of had air suspension and QTII or QDII theoretically. The one way to tell is the rear diff. If you have QTII you have a 195mm differential ,if you have QDII you have a 230mm differential. All are made by the German company ZF. Both systems are good and utilize the same transfer case, with only difference being that QDII has the ELSD. QDII is better but smart driving and learning how to use the Select Terrain system is key. QTII will get you there it might just take some better driving and more patience. I'm on my second WK2 with QTII. I opted for that because I did NOT want the air suspension. I lifted my Jeep(Dobinsons Suspension) and for what I do it's perfect. I've done trails that my buddies have done in their PRO4X X-Terra & Tacoma TRD Pro. The WK2's capability drastically was improved with the new 8 speed ZF transmission. With a 44:1 crawl ratio on V6 models you can really get into some gnarly stuff. Choose a good line and lock into 4LO and these vehicle will surprise most people.
I contract for ZF and I support this message!!!
I have quaddadrive 2 in my 07 jeep hemmij
How can you tell if a gc has qd2? I know it came on 4 trims but when I’m looking at listings it’s never in the specs, I see qt 2 sometimes.
According to my build sheet, I have QT2, QD2, and rear ELSD on my 12 Overland Summit 5.7 4x4.
@@urbangroomer They'll tell you. No, wait that's how you can tell if someone drives stick.
I have a WK1 with QuadraDrive2. It feels unstoppable. Even in sand. It has Vari-lock in the front and the rear
What is wk1?
@@MerlinMoorlo Jeep Grand Cherokee 05-10
The ELSD in the Quadradrive system operates like a fast-acting soft locker. It locks very quickly at very low speeds, unlike many other lsd's that only lock when you have both wheels turning before one starts to slip. Quadradrive ELSD is virtually instant engagement of the LSD.
Yes. I have found this to be the case.
I have the only WJ 4.0 Quadra Trac 1 system I'm aware of in my area. Hard to find videos on them 4wheeling
The clicking noise was the front drive shaft in my wrangler when there was a lot of resistance on both front wheels. I diagnosed it myself and replaced the drive shaft with one using a stronger joint and it resolved the clicking noise.
Thanks for a great video. From my experience with the QTII, no need for extra throttle ever. Extra throttle will lead you to lose control over your vehicle. If you started climbing at the right speed, and the BLD, QTII, kicks in, stay exactly on the same throttle. It would take between 1.5 to 4 seconds to pull you out of the situation, with less harm to the Jeep and more control to the driver.
you probably dont care at all but does any of you know a way to log back into an instagram account..?
I stupidly forgot my account password. I appreciate any tips you can give me.
@Koda Harlan Instablaster =)
@Magnus Jaxtyn I really appreciate your reply. I got to the site on google and I'm waiting for the hacking stuff atm.
Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.
@Magnus Jaxtyn It worked and I actually got access to my account again. Im so happy!
Thanks so much, you really help me out !
@Koda Harlan You are welcome :)
Great demonstration, I would love to also see a comparison of the QT1 vs the QT2, I realize the difference is QT2 has 4x4 low and the QT1 does not but I would really like to actually SEE the real world difference it makes in the WK2.
I second this. Would love a break down with the QT1 in the mix.
I was wondering if there was footage of my Jeep slipping backwards up that hill every time I gave it gas. You warned me to watch out for trees at the top and then I promptly ran into one about 30 seconds later. Lol. Such a great time. Enjoy all that delicious pizza!!
Always a blast to head out to the trails with you!
I have been driving Grand Cherokees for 28 years, two for 10 years each, plus the present one is now 8 years old and find your videos very informative. Many thanks.
durable strong suvs!!
Both systems can direct more torque to the front or rear axles.
Quadra Trac 2 uses brakes to get more torque to a specific wheel.
Quadra Drive 2 uses an electronic slip differential to get more torque to a specific wheel.
Yep, But only the rear has the ELSD in Quadra Drive 2
@@ProdigalOverland so on the QD2 the front uses the brakes like the QT2
@@johnviera3884 yes. In the current version (wk2) you only have a rear elsd. The front is the same. Open brake lock differential as the qt2 system. If you watch out latest video you can see it’s limitations
So quadra-drive 2 over quadra-track 2... Got it! Thanks for the video and showing how it works, always wondered about that but no one really explained that well
Happy to help!
Every WK I've owned states what drive system is fitted on the centre console. 😎
From what I can tell, if you have a low range button, you have the QD II system, the base model has the Selet-Trac, if you have a Neutral button its a Quadra-Drive I. Some models have the system written on the center console. Get the Quadra-Drive II if you can. The QD II is standard on Limited models of the older WK 2005-2010.
My 2008 WK Limited 4.7 has QT2, 4Low and Neutral. Maybe the Limited 5.7 has QD2 standard🤔
@@omaralexanderarmuelles2259 Yes because i have a 2005 limited and it does have the QD2
@@omaralexanderarmuelles2259 I have a t handle lever for 4 low next to shifter
@@datcrazywhiteboy6205 5.7 Hemi right?
I am glad I've hung onto my 2012 GC Overland as newer models no longer have the front e-LSD. So far I have mainly used it in beach/sand driving and mostly get away with selecting Sand/Mud in Selectatrac but for serious deep sand, the QD2 does a great job in low range with the fully locked diffs/transfer case making it almost unstoppable. This video shows that QT2 looks like a poor cousin and while it gets the job done, it needs a bit of finesse on the the throttle with a fair bit of drama whereas the QD2 makes it look easy. Shame on Jeep for dropping the e-LSD option.
The Quadradrive 2 worked best in the earlier WK models with the ELSD front differential. Moving away from ELSD in the newer years made them far less capable..
QT I - has front and rear open diffs, it uses abs and traction control to help manage wheel slip. Great for light trails.
QT II - has an open front diff and limited slip rear diff, it also uses abs and traction control to manage wheel slip. Great for light duty and moderate trails.
QD II has electronic limited slip front and rear diffs (called ELSD). It can also use the abs and traction control systems to manage wheel slip. QD II systems can control the transfer of power between front and rear diffs as well as each individual tire. It can also fully lock the front or rear diffs similar to an aftermarket detroit locker or the Rock-trac system found in the Wrangler Rubicon and Gladiator Rubicon.
The easiest way to tell if you have QD II is to look on top of your front and rear diff, there should be and electrical connector on top of the housing, this connector is for the locking actuator. QT I system will not have this QT II may or may not have an electronic actuator on the rear it may be a mechanical lsd depending on the year.
If I am not mistaken all jeeps (wk2) come with traction control TC, this feature breaks the slipping tire to allow the opposite tire to spin (because open diff) sometimes this is not enough and you need more power and TC will keep braking your tires, you need to turn off TC and accelerate while breaking (mildly) this way you force both tires to spin at the same times. I mostly use my hand break at half to force the two rear tires to spin at the same time.
The clicking noises is when you enable 4lo and the TC gets disabled by the computer, then there is way to prevent slipping, but if you have QDII the ELSD gets activated and disabled To transfer power from one tire to other, that noise is normal.
QT - capability to have AWD by adding a differential in the Transfer case
QTII - AWD with LSD in the transfer case
QD - LSD front and rear
QDII - ELSD front and rear
QL - Air suspension
TC - only works on 4Hi or AWDm and uses the ABS computer to achieve power transfer.
(LSD-limited slip differential)
(ELSD- electric LSD)
QD Quadrant drive, QT quadratrack, QL quadralift
QDII clutches are controlled by a computer and cannot act as lockers, QD acts by centrifugal force, me in you have to accelerate for the clutch to engage.
If I am mistaken please feel free to correct me.
I have a 1999 wj with 4.7 and Quadra drive in it we just got our first snow and ice so far so good
Hi, I have a QUADRA DRIVE II on my 2007 JEEP Commander CRD...and I love it!.
Thank you for your illustrative video!
Starts 3 mins in...
Thank you for saving me 3 minutes of extra life;]
Tks Man! I have a 99 Grand with Quadra Trac II and I just bought a 04 Grand with Quadra Trac II with only 93k miles on it today. I'm very excited about it but I want to say thank you for the explanation, now I understand more and feel more Learned! Tks man! I'm in Eugene Oregon BTW . We have lots of mountains but very little legal trails if you know what I mean.
My 99 WJ 4.0 is quads Trac 1 system and on dirt climbing hills it's great, haven't tried it in mud yet but won't spin a tire up dirt hills regardless how steep. I like mine
Would love to see a comparo of the WK1 & WK2 QuadraDrive II systems. The WK1 system uses an electronic limited slip (up to full lock) on the front as well as the rear.
yo tambien tengo wk1-06 qd2 y bloquea mejor que ese trailhawk. vaya qd2 mas rara, que le ocurre?
@ posible qd2 questa mas?
@ Desde 2011 el sistema Quadradrive2 solo tiene diferencial ELSD trasero, al diferencia del tuyo que tiene ELSD adelante y atrás.
Where's the love for the wk qd2 with front and rear lockers ? It's a shame they stopped putting the front locker in when they went to the wk2.
It is. And we need wk owners to come out with us. In order to show that love. 😁
@@ProdigalOverland I'm in MI with a WK QD2
@@JordanKaczmarczyk we will be that way in May
Totally agree. My WK2 QDII is a better, more comfortable all around vehicle in every way than my old WK QD2... but the WK was absolutely the better off road machine. It crawled tank-like over most obstacles.
Hello. My 2005 with 5.7 and QD2 with 2.5 inch lift, is a heavy beast. With proper throttle control it goes just about everywhere except when it won’t. Usually the weight or lack of clearance is my issue, and my poor throttle control. I’m working on two pedal throttle control to become better. An awesome spotter is even more important that can see the proper line when I cannot.
Your vidoes are VERY helpful in going into the details of Jeep drive and suspension for the WK2. Jeep should consider you as a spokesperson, IMHO. I'm currently searching for a WK2, and as n3rd eng1neer geek I really want to dig into the details as to which rig I pick . You have helped my decision. Thank you!
This is really good. Should be posted on Jeep's website. Spot ON! I would never have the guts to take my WK2 / Quadratrac II through this terrain, but it is good to know that it could do it. Is Quadradrive II a true locking rear differential, or a limited slip differential? Brake lock differential really helps. For on road use, Quadratrac I or II is all you need.
Hello. According to what I read on 2005 QD2 5.7 limited, the QD2 with front and rear limited slip can send up to 100% power to the one wheel with traction and lock the front and rear anywhere in between and all the way up to 100% full lock.
Another very informative video. The differences between the two systems is crystal clear now! Thanks yet again, Brad. See you in about a week.
Absolutely! Looking forward to it!
I have the 05 Quadra drive 2 trail rated Hemi and I can go everywhere I want and I do not spin tires. Great video. Great explanation.
@ZenoSwarm Sucks! Cool.
Great informative video man. You explained it very well and the clips you added were a huge bonus. I’m glad I came across your page.
Thanks!
I had to trade in my WK because I need a truck. The truck is great but the WK has been my all time favorite vehicle.
In the past that clicking sound was concluded by some to be the transfer case slipping, not sure if these still use a traditional transfer case with a chain like the older jeeps. Definitely interesting
100% true ive definitely experienced a slipping transfer case in my Jeep SRT aswell as GM light duty pickups occurs often when u have the front axle in a high load scenario coupled with larger tires the Jeep transfer case seems to be very heavy duty and can take a beating. Just be sure to change the fluid more often as that is an extremely important item to keep in mind
RIGHT I STILL HAVE THE BEST 79 JEEP CHEROKEE WITH QUAD TRAC AND EMERGENCY DRIVE IN GLOVE BOX. ALL TIRES LOCKED OUT TRANSFER CASE LOCKED FRONT TO REAR AND CHAIN DRIVEN. BUT AFTER A WHILE CHAIN WILL WEAR OUT AND SLIP. THOSE FSJ WERE ALMOST UNSTOPPABLE. GAS MPG..LOLOL I GET AROUND 9 WITH THE 360 AND 401.. AMC BLOCK OF COURSE.
Nature's challenges, conquered! Offroading enthusiasts, dive into the heart of this thrilling video.
This was SO helpful for me understanding all that stuff! I’ve got a 2013 Trailhawk with the Quadra Trac 2 system and I have noticed a couple situations where staying on the gas and letting the Jeep work out the terrain itself worked out! Now I know why so thanks for this video! The comparisons with you talking about it made it very easy to understand
Thank you, great video.
I have a wk1 diesel with QT2, I live in Canada and the winters get rough, but with my little tank, never had an issues getting out of difficult terrains.
Thanks for watching! Have fun out there!
Very informative. I am picking up a new Summit with the Quadra Drive 2 and the Quadra Lift Suspension. I was very curious on the difference between the Quadra Drive 2 and Quadra Trac 2. Now I know I bought the right one. What I really like is how the suspension automatically adjusts depending on which terrain selection the driver chooses - select the terrain and the Summit does the rest. As dummy proof as you can get. Thx!
Bought a 06 Grand Cherokee 5.7/QD2. I don't do off roading but we get a lot of snow. It doesn't disappoint even though it has shitty tires.
Those are mean machines. I just bought one a week ago and love it !!! Tires also plays a big roll in traction...
This was a really good video!! Actually was really fun to actually can watch working the both systems!
Glad you enjoyed it
The Quadra Trac I in the base 4x4 Laredo, as explained to me by my service tech at the dealer, is, "basically Front Wheel Drive which uses Traction Control to mimic a Limited Slip rear Differential." But, I don't know if that's actually correct.
Does it go good? 4.0l?
I love my 06 WK with Hemi and QD2. I've put an OME lift on it and BFG KM3's and can go anywhere
Thank you for your comment! You mention "OME lift". Does that include an OME full suspension overhaul or is that purely a "lift". I don't know much about suspension or OME so if my question doesn't make sense or seems unnecessary that is why. Thank you.
Quadrack ll,
The spinning axles engage the servos in the axles that lock the differentials. There is also a servo in the transfer case that lock the clutches in the transfer case either in 4 high or 4 low.
4 high is full time 4wd and open diffs front and rear in high range spinning locks the diffs and t case.
Pro tip learned 1/2 to 3/4 of the way through this trip. If you have quadratrac II give it a little gas before letting the break go and it will help you crawl out.... at least with the ecodiesel. Awesome video Brad!
Thanks for this. Good tip!
I had a 2017 GC limited 4X4 on the 18in wheels and then I had a 2019 Summit 4X4 on the factory 20in Pirellis and the way I can describe it is that I felt the Summit with the Quadra Drive and Air Suspension made going through some scenarios extremely easy…. While having TRD Tacomas getting a bit stuck 😂
Thanks a lot, I've been looking stuff and specially videos that describe how wk2 act off-road and all what I was finding were musical videos with wk2 passing by obstacles that my tiguan do everyday, or at the best I was finding videos of pure footage with no description and technical knowledge behind... so useless videos for the pleasure of the eye only. This video is the best I've seen and so far I feel that I knew some very very clear and useful information ! Thanks for your scientific spirit.
Sure thing! Glad it was helpful!
For $500 you can put in a rear locker that works without air pressure or the like to engage and disengage.
Your a legend. Ive been watching you for a while now. I must say i have learned tons of info on my Wk2 now.
Thank you and keep up the excellent job.
Love all the way from Oman 🇴🇲
Great demonstration Brad on open differentials! 4Runner for ever thought. Lockers, rear and middle dif locks are essential for your type of of terrain. I hate electronic assistant features that nowadays are common on most real offroaders0 having the right tires with the right pressure and most importantly a competent driver is a must. However, as seennin your video both Quadra trac 2 and Quadra drive 4wd systems are doing their job flawless.
The WK ( WH in some markets ) Jeep Grand Cherokee Quadra drive 2 has front and rear electrically operated limited slip diffs and a center diff in the transfer case and low ratio so all the engine power can be directed to 1 wheel if necessary .
One of your BEST videos. Love to show it to friends of mine who think our GC can't go some places
Glad you enjoyed it!
Thanks for making me look at my 'new' used GC Trail Hawk window sticker and realize I have the Quadra-DRIVE II
The clicking sound are the cluthes of the limited slip diff slipping.
Quadradrive II is awesome. I’ve got it on my WK Hemi. I’ve had a lot of modified rigs and the Quadradrive II has been the best I’ve experienced.
I am going tomorrow to buy a 2006 WK with Hemi and Quadra Drive II system. It says Quadra-Drive II near the low range handle, so it was easy to see what drive it had. I think it is a good deal at 7400 bucks.
Very good explanations of the various Jeep drive systems, Brad. Until I started following your channel I didn’t know a Quadra Trac, from a Quadra Drive, from a Flintstone mobile. Now I “Yabba dabba do!” ☺👍❤
Bro, great explanation! Thank you 👊🏻
60 seconds into the video and already crazy thankful for it. Very curious about how to tell which I might have and how they behave side by side.
I can say I have a '23 Power Wagon with front and rear lockers on 37's and Carli King Suspension and the Cherokees can do a surprising amount of the tracks I tackled. Reallly good tires with proper inflation seems to be the big differentiator. Just my two cents. Take someone who is setup like me along with a 13k winch to be there just in case....
This was a great video on the workings of both systems. I have an 08 GC Overland, Quadra drive 2, I’m fairly new to all this and the only problems I’ve had so far has been due to operator error, just not knowing what I’m doing yet. My friends all have wranglers, rubicons, and sports so they are a bit different than me lol. Thanks for the videos.
Glad you enjoyed it!
Your 08 grand cherokke actually has a better QD2 system than the new ones... your has the ability to fully lock all 4 wheels (basically like a rubicon)... unfortunately jeep stopped using that system in 2011...
I have a '23 JGC Laredo w/ the QuadraTrac 1 (QT1) system. You can borrow it to shoot a comparison video if you like. QT1 vs QT2.
Learned a bit from this video I've been a ford guy and I've been thinking of making the switch to jeep.
I don't know what the popping sound is, but I'd be really doubtful it has anything to do with the bakes.
Can't think of any brake component that would make that sound.
I'd more suspect a transfer case noise or a differential noise -- like a posi-track engaging.
If a CV joint or a U-joint made that sound, it would likely fail immediately.
But good overview -- appreciate the analysis.
Very well explained, great comparison
You should monitor the 4WD system Via alfaOBD and you can watch what the rear ELSD and how/when the center t-case is applying power to the front axle.
Then, I'd like to know what the default front/rear torque distribution is with Quadra-drive II, and what the system is capable of shifting front and rear.
I've tested that out and posted on jeep garage. In most day to day driving the system operates in RWD in my post on Jeep Garage I go through it.
th-cam.com/video/yWYxmyu3Vc0/w-d-xo.html Low speeds and at a stop the system send a bit of power to the front wheels, but after taking off reverts to RWD
great video with really good information. I am about to order a new GC and have been on the fence about which system to order. This helped make my mind up. I was leaning towards the QD2 but wasn't sure of the difference. Thank you for the great comparison.
Awesome! Glad it was helpful!
Thanks for this video. I'm having trouble figuring out with Grand Cherokee will be good for me. I don't plan on going to moab or any of trail as tough as you guys are going. I just need to be able to get through the snow and to camp grounds that RVs would get too. I think I can get the lower trim 4x4 and I'll be ok.
yep, just get a 4x4 and you'll be fine
Thank you for detailed explanation the difference of 4WD Jeep's sytems.
I have understood it, finally:))
I have a 2014 wk2 diesel. Getting ready to lift. Im not sure even what the drive train is but it has the knob in the center with mud, snow, sand? And 4 low. I think its front wheel drive but uses allwheel drive when it needs to. It have cenrer diff and front and rear lockers.
I had a 15 WK2 with QD2, buddy in a Nissan navara (uk) with 33” 50/50 tires couldn’t get up a gradient in snow he kept skidding back down. I put my GC in snow mode and glided past him on the standard road tires 😂😂
Nice!
Active braking is not "in the axle". Active braking is controlled by the ABS system under the hood.
I actually have a 1995 jeep grand cherokee limited ovis 4.0iL the the frist gen quadra-trac awd and its my trail rig and daily driver its a beast off road
Should of pulled the E-break and slowly apply give it gas. Will work like a dif luck on the back axle.
Excellent explanation, I have been waiting for this Thanks !!
I’m glad it was helpful!
Heads up for buddy who doesn’t know what system he has, if he raises his back and (to do a tire change) and he manually spins the tires they should spin in opposite directions if he has an lsd
05 to 10 was had the better Quad drive 2 system. Wk2s has ELSD only in the rear. Wks have it in the front and the rear. Both great
Brilliantly done!
I read that the new WL Grand Cherokee will have the eLSD on both the front and rear axles when equipped with the QDII system.
Great! Useful video!
Hello. The story I’m telling myself is that to keep the throttle on so the system can work as it’s supposed to, learning to use the left foot to apply brake pressure at same time as needed to modulate speed is just as important. When I’m trying to get over a tough obstacle, my instinct is to give it more throttle to try and power through instead of applying steady throttle to let the Quadra drive 2 do its thing. Then I end up using too much throttle and it is not a graceful entry or exit.
Then one time in band camp….. I hit the accelerator instead of the brake and that almost turned into a disaster.
All the lower end jeeps in my area come with quad track 1, it's funny to me that the quadra-drive is thrown into the overland/summit models in my area as if people buying the luxury segment of this truck would actually take them off road to the degree that it's needed.
Great info in the vid! I have a jeep commander with a 4.7 and qd2. See any Jeep Commanders out there?
The previous version of QDII has front and rear ELSDs (Electronic Limited Slip Differentials). I have it on my 2006 Commander Limited and it is an awesome system. Does anyone know why they did away with the front ELSD starting in 2011 with the WK2?
Is this on all the pre 2010 ? WK1s
@@lweleven3423 It would be on the one's that have the Quadra-Drive II system.
My understanding is the WK had a far superior QD2 system with both a front e-LSD and a real e-LSD. The WK2 has more of a QD1 system as Jeep cut costs, eliminating the front Eaton e-LSD as Mercedes at the time didn't like the GC being better off road then the ML320.
FYI try some kombucha and a serving or two of kimchi to combat the pizza-indigestion 😂 works like a charm for me.
Another great video thanks mate
I would agreed 100%. If I knew and I had one with drive 2 I would more likely keep it.
A 2011 - 2013 JGC equipped with Quadra-Drive will display "Quadra-Drive" in the VIC when you power the JGC up. I don't know if a 2014 and newer JGC says Quadra-Drive" in the display but I have seen pics of the newer display in the 2014 and newer JGC that shows an animated display of the drivetrain that shows articulation and if the JGC is equipped with Quadra-Drive, it shows a lock symbol over the rear diff. Brad, you should be familiar with what I am referring to.
2014 and newer does not display any quadra drive labels anywhere
@@TnTTyler, there is a video here on TH-cam that shows how to tell if your 2014 and newer JGC has Quadra-Drive but from past experience, it appears that the forums of the Prodigal Overland videos don't allow links to other videos, or I think links period. It's as I described in my original comment but the JGC has to be in 4wd Low Rock Mode and the lock symbol appears over the rear diff in the display whenever the ELSD engages.
I've made videos showing how to unlock and lock the ELSD on command, in both 4 low and 4 high on my channel
th-cam.com/video/Wo3lggTfkRM/w-d-xo.html
I'm pretty well versed in the system as I test and monitor it all the time.
One of the last clip - Dennis going up incline: Couldn't he have used hill descent assist to go up that easier?
Do the QTII guys ever try using the "left foot braking" method to help out the active system? --applying some braking force with the left foot while on the throttle with the right? I wonder if that messes with active braking system or if it still will apply additional force to the low-traction side...
Left foot braking will definitely give them more “quadradrive II” like smoothness over obstacles, with less vehicle surging. That technique will also help the front end of the QDII system sort things out more smoothly as well. I’ve always preferred crawling over obstacles this way when possible rather than careening over them due to excessive throttle input which can cause loss of control and crashing of the vehicle onto the next obstacle in a series.
Great video, very informative! But how do I identify QD2? I’m specifically looking at 2014 Overland models. Is there an easy way to Identify?
This is great I’ve learned a ton from you.
I’m confused. My 2017 GC build sheet at top says Quadra Trac2 then near the bottom says Quadra Drive 2 yes I have Air Lift System. 195mm front axel 230mm rear axel. Elec LTD Slip Differential Rear
QT1 with good tires, aired down, the right line, and 1st gear will get through almost anything. Just bought a limited GC-L and forking out the dough for a overland or summit to get QD2 is not worth it to do light off roading IMO. Plus who buys a GC to primarily off road? I would think a 4 door JL would make more sense.
Bought a Trailhawk because it has the QD2. Handles well on the beach in the deep sand as well.
It sure does!
@ZenoSwarm Sucks! not every overland has the qd2. But it is an option.
Hey friend, haven't you had any more problems with the sound? In my case they have told me that it is the transfer chain that is slipping, and the sound gets worse every time
Why didn't Jeep ever tell me this. I never knew about the active braking in 4wd and now I know how to use it properly Thank you Thank You
That popping sound sounds like it's jumping gears somewhere.
