Only took me 87 videos and three weeks to find this genius on TH-cam!
Not me wanting to know this for years 😭.
Save the video if you ever need it again.
this is the kind of video TH-cam should feature.
I have been a mechanic for almost 30 years and you just taught me something new! Thanks a million
Probably wouldn't brag about that, just say'n.
@@andrewpropes3646 probably wouldn't be talking with a dumb name like that just sayin...
thats a compliment,,, to 'both of ya',,, think bout it a min :)
@@andrewpropes3646 Sorry Andrew, you must be a young man because only a young man would make such a rediculous statement!
@@jaysantos514 this true, you are correct
Wow, I’m a ford technician and I learned a lot. Very intelligent. Thank you for the gear ratio lesson!
Weird to see you here brother😂👌🏻
maybe you can pass you power train ASE exam now
What?
No wonder Fords are left on roads dead🤭
Haha, this really puts a lot of things into perspective when it comes to ford
i may have actually paid attention in math class if my teacher used examples like this
EXACTLY
Kevin Yourk yeah. Right. But I guess back then when ya in school you would equally hate to learn anything mechanical.
I agree 💯 percent
So what about 31/18.5/15/with a 430/gears with a 35 fool spool 1350/ c10/ 2/ wheel drive with a/ 400/an a 496 roller tlk back bud
@@tramelponder6600 Simple, put it in "P" and walk.
I've been waiting for you guys to do this video for a long time and I was NOT disappointed! Thank you this video was very well done and very helpful. Keep up the good work guys!
I knew absolutely nothing about gear ratios before this video. I feel like I need to swap out my rear-end now thanks to this guy! Amazingly detailed information.
Wow! I have discalculia, so I tend to shy away from math, but this lesson has me COMPLETELY understanding it and the formula is memorized, which is odd for me. I just bought a Dakota 4x4 that the guy put a rear end out of the Dakota suburban, which is very high, and you can't go in 4 wheel on pavement or hard surfaces, as it fights itself. Gotta find a stock gearset.
Awesome vid! TWO of my favorite Jeepers in the same video - LOVED seeing the really obvious trail-capability differences as well! When StepChild walked up those obstacles and made it look insanely "honda-civic" easy, and the OL rigs both had to work for it...that was fantastic!
Your videos are a great additon to Matt's and the Bleepin lineup. Thanks!
Great job on the video! Usually I end up more confused at the end than when I started. Very informative.
Good job getting this info out man. Some of us know this kind of stuff like it’s a normal thing but I watched your video to see how you would present it. Well done.
Great explanations on what to look out for re-gearing. Helps a ton!
So incredibly helpful man! I've never messed with re gearing and this gives me so much ease of mind when I go to tackle my YJ!
This guy had explained something to a newbie off roader flawlessly. Sub and liked. Amazing helpful work my friend, thank you.
Professor Gearhead! Man, that was great. Detailed, informative and enlightening.
extremely helpful! I realized how much I did not know about gearing after watching this. This definitely helps with my build planning.
Straight up awesome info. I knew most of this but not the formula for figuring the gears/tire size. Thanks, belatedly!
This was a really clear explanation of gear ratios and extremely helpful for understanding what they do. Thank you!
Again. An excellent clear description of the ratios and considerations for swapping to larger tires.
Very informative and well put together HELPFUL video, I’ve sent this to friends lookin to change their ratios and it’s helped so much.
I'm impressed with your easy to understand explanation! I am so confident now to finish replacing with my soon his XJ Cherokee front differential, and be able to mach it to the rear diff. modified by new 35" tires..... Thanks a bunch!
Wow! Great video. I have not learned that much about anything in such a short while. Thanks a lot.
This is the best explanation I've seen for diff ratios. Great video!
Thank you for the clear explanation! It makes it perfectly clear what all the issues are that arise lifting the Jeep or throwing on a different size tire. And if you are not a mechanic what a nightmare you can create for yourself because of the lack of knowledge. Awesome video.
left for almost 6 yrs and this man is still taking me to college... thanks man... appreciate ur time and teaching.. ty..
This is an example of someone teaching you who knows the subject well. Thanks for clear and to the point explanation.
Dude this video is hands down the best explanation of axle gear ratios I've seen after looking casually for the last couple weeks. Im going to keep watching your videos and hope you have other topics like this.
Great video for a Jeep newbie like me!!
Bleepingjeep video’s rock and are so helpful!!
Been doing axles for 50 years, I never claim to know it all and crazy how you can still learn something you didn't know or at my age forgot. Lol.. Great job on the video.
What axles would you recommend to one ton swap a rwd auto MJ?
@@maxnovakovics2568 any more these days, it seems like Teraflex has got it figured out and would have whatever you need. Plus, a lot more knowledge than me. good luck 👍
Easily one of the most informative videos I've ever seen. Thank you.
Seriously just been schooled
Great video. Thank you very much. Just did a lift and 35s on the Rubicon. This answered my questions. Good job!.
Normally car terms go over my head, but you explained everything so clearly, and now I really feel like I have a better understanding of what I need to look out for. The math equation was super helpful as well and I will be using it!
Brilliant ! Really well done mate . Your knowledge and presentation skill is to be commended ! Thanks so much for all your effort putting these vids together , they are a great resource and I for one value them greatly !
Cheers from Australia
Hey mate! How much is a set of Maxxis tires down under 37x12.5r15?
Very good video. I’m not a 4 wheeler, but this applies to street tires too. To keep things clear in my mind I’ve always equated gear ratios as revolutions rather than numbers of teeth unless I’m looking at actual gears to determine the ratio. So a drive shaft would turn 4.11 revolutions for every single tire rotation in a 4.11 rear end for example. I especially liked your formula for determining the gear set needed for a tire change.
Great segment, man. Hopefully by watching enough of these helpful vids, I can stop asking my brother-in-law every single question I have about Jeeps.
That was an excellent tutorial and clearly thought out and presented. Well done. I learned a lot. Greetings from Arizona.
This guy is so damn helpful.
+TytheBandit Thanks!
Tyler Bleepinjeep
Damn helpful!
I'm new to this off-road technicalities
I plan to get a Jeep Wrangler 3dr or 5dr sport since rubicon is so much and I'm not an extreme off-roader.
I plan to put a 35" tire with a 3inch lift
I'll be using this jeep as a daily commuter/occasionall off-roading.
Do I need to upgrade my gears? I would value your insights on this. Thank you
TytheBandit and apparently very cold.
Absolutely!
You're an excellent explainer. I'm a college graduate but have very little mechanical knowledge, and I believe I understand about 90 percent of what you explained in this video. Thank you very much!
Y'all knocked it out of the park on this one. Great job!!
most informative video I have watched! he explains gears in a way anyone can understand!
Great stuff man! I own a Tundra, but you’re knowledge of 4x4 related material is unbeatable. Thanks for posting!
awesome video man now I understand axle gears I had no idea before watching this so thank you.
First thing I did when I finished watching this video was to like and subscribe! Clear and concise explanation on how gear ratios work. Thanks
Fabulous video. I'm a noob gearing up to rebuild a Dana 60 and a Spicer 10.5 for a E-Van 4x4 conversion. Lots of great info in this video!
Thank-you. Very well explained.
Ugh, best video from this channel
Tyler, thank you for the great video! I've got a Ram 2500 that has a 3.73 ratio and I just put 35" M/T's on it without considering the gearing I had; your video has me already researching how to fit a Dana 44 4.27 after doing the math. Spot on! Thanks again.
Very good video. The information tells you everything you need to know about understanding gear rations. This is the information, your local shop, will not tell you, so I'm giving it a thumbs up, and subscribing.
Excellent! Can get college credits for having taken this short course?
lol
I agree very well done
another rule of thumb I was told years ago...and it too is a 'guideline' to compare to. I would still use your calculation too. But, it goes like this: for each inch in diameter you increase, it's like subtracting .1 from your rear end ratio. So for tetnas, when you jumped 4" in diameter, you needed to come up with an extra .4 for your 3.07s...so 3.47s, rounding up to 3.55s
I don't have a Jeep anymore, but this was extremely informative!!! This helped me understand the ratios and their relation to my tire sizes. ALSO - this helped me solidify my decision to put 4.56 gears in my 4Runner (up from OEM 3.73). THANK YOU!!!
I know this is over 4 years old. GREAT POST. I knew a lot of this but not all. Super helpful!
Who else wants to send him a space heater
Is that why the camera is so shaky? Brrr?
Do not forget a Heavier Tourque Convertor it totally helps ..
😂😂😂, poor guy is freezing.
This was very helpful. Thanks. I do want to ask if you can do a video class on differential rebuild/setup. Start to finish. Measuring for all the shims, back lash, preload, what tools, etc. Since you are a great teacher and most of us can’t go to a school for this training it would be a GREAT service to your viewers. I know it would be long and hard but I believe in you, you can do it. Nobody else has, I’ve looked. Again THANKS.
Yes, that would be amazing. I can't afford much but I'd pay to learn by watching the video.
Edit: he has a Patreon page for donations. We gotta help this guy out for all his useful information
Just want you to know I'll probably never ever have to use what you just did but now I know how my rear end and front end work I leave it all up to the professionals like you thanks for the video very cool
I couldn’t find any videos on YT that could explain gear ratios! You’re the only guy that could explain it! Thank you!
Awesome video! I loved the formula you showed, as I have been wondering what gear ratio to go to in the future. Right now I am running 31" tires with 3.73 gears, and in the future I want to upgrade to 33"- 35" and have been wondering what gear to go with. With this formula, that question is now answered :)
+TxGamer13 I used 4:88 gears and 33" tires. Most guys will say that's too low. But I love it!! I bought my Jeep to run good at slow speeds in the dirt, and I was willing to sacrifice some high speed performance. You can go 65 on the highway at about 2600 rpm, but you don't want to go much faster. However, the low range is creepy crawly. It Is Awesome. I have a TJ with the 4.0 and the AX15 transmission.
7:30 the illustration there really helped it sink in and comprehend it. kudos
Good class, Teacher..!!!
I Really liked the Tire Size for you gearing section starting around 5:00 on the clock... !!
And your First sample problem "WAS" my Jeeps set up to boot.!!
This was an extremely helpful video for me, you did a great job explaining yourself. Thank you
I learned something new today.
Thank you
Thanks. This made things a lot clearer.
Yo dude I know this video has been up for a while, but I just bought a JK well like six months ago and I’m upgrading to 37 inch tires and this video is a lifesaver. Good stuff brother!
Stay safe, wish the best happiness and health for everyone
Excellent presentation! It was very clear & concise. Your voice cadence & explanations made the content easy to follow and comprehend . Thank you!
Fantastic info. Just answered my question on gears wanting to run 37s.
OMG dude you just saved me a lot of money in possible damage. I stumbled on this video by accident, and Im glad I did. I already purchased a 3.25 lift and 35's for my 14JKU. I had no idea about the gears...Thanks again!
Thank you. I now have an understanding on gear ratio for when that time comes. Impressive and informative vide. 10/10
This is brilliant man. Thanks for this! My son has his eye on a used Wrangler with huge tires and I wanted to make sure it was set up properly. You just armed me for my research!
finally, someone I can understand when explaining that...
thanks
awesome job man. Earned a sub here
Thank You Very Much for an excellent, detail explanation. I'm in the process of buying either F250 or 350 and going thru options to choose this subject raise many questions for me and you certainly helped me to understand it. Much Appreciated.
An excellent video for someone like me, who’s never been trained or exposed to auto mechanics…Very educational, thanks!
really great video. thanks a bunch.
VERY informative. Thanks. :)
Thank You Very good explanation of gearing I have been searching for a video like this for sometime. It took me buying a jeep and doing research on gearing for this video to come across my feed. again thank you
You explained everything to me perfectly and I had no knowledge of how gearing worked. Thank you!
As a scientist I have to tell you your videos are great. Very detailed and well explained. Your thoroughness makes these vids extremely helpful. Sometimes a person thinks they need to know one thing but what they really need to know is something different that they haven't considered or were unaware of and your videos can point those things out. Hope you keep making them this well.
Thanks!
Krushim why "as a scientist"? makes you sound slightly arrogant
@John Edwards I would think that is self explanatory since everyone knows how thorough and detailed scientists are in their work and explanations just like he was here. It is a fair comparison and a good compliment to his efforts. To suggest that is arrogant says more about you and how you feel about your own experience or education. If he was giving legal advice/explanations on something and a person said as a lawyer myself I have to tell you that you did a great job you'd be an idiot to bash that person. It's the same thing. Compliments from peers in an area are always appreciated by those that receive them.
Krushim yep arrogant as fuck...if you're so thorough why have you edited your comment and still made a typo? you are not more important than anyone else.
Clayton Magnet I second that
Only you and George Costanza have a coat that puffy. Love this video. Thank you!
I don't understand how it took .e long to find this comment about the coat lmao
Very instructional video, step by step for any non-expert to follow. Great Vid
Very easy to understand with your patient and detailed explanation. Thanks brother.
Thank you soooooooo much for this great video
Right?! About time someone explained it like that!
Great stuff, ty. One little technical point just because I'm an engineer. You mean 20 thousands not 2. Keep up the great work.
He meant 2 hundredth. Mathematically the same. But easier for non-math peeps to understand than 20 thousands. No trailing zeros needed here.
Thank you this was an excellent video explaining the gear ratios. I learned a lot here and now I can make a more informed decision.
I actually learnt something useful today. Thank you so much for explaining it all in an awesome way!
super helpful
damn dude, you live on Hoth or what? thanks for informative vid. I'm going from 3.21 to 4.88 on my JK with 35s soon.
It sure feels like Hoth when the temps go below zero. You're going to love the 4.88's. Your jeep will feel like a brand new car.
Tyler Bleepinjeep I love the 4.88s! wish I'd done it sooner
RDubya73 lol
im going to 4.56s from 3.21s in my jk on 35s. i about went 4.88s lol
Tyler Smith my 85 Chevy came factory with 4:56 my top speed is no more than 60mph....M-1028
Awesome Video. I'm just getting into and preparing to start off-roading (again after years away from it) and will be 'building my own' Jeep. This has been extremely helpful. And delivered in a wonderful way = smart, down-to-earth, not at all condescending (and there is zero sarcasm here which is Abby Normal for me).
Thank you. Really just an EXCELLENT video demonstration.
Very informative. I was confused by axle gear ratios but this video gave me much information.
on gear fudging, don't you mean hundredths, not thousandths
The difference is in the hundredths place (0.02), but the difference is about four thousandths of the base number (0.02 / 4.88 = 0.004 )
If you go to a machinist and ask him to cut one thousanths off, he will cut .001". If you tell him to cut ten thousandths he will cut .010". If you ask him to cut a hundred thousandths or one hundred thousanths he will cut .100". If you ask for a tenth he will cut .0001. I think that is why Mike asked the question.
@@lockcracker I work in an engine remanufacturing company and train machining parts and assembling engines. You are correct and so many people get that confused
I think I’m more impressed with those kick ass iPhone gloves!
Who is this guy👍🏼👍🏼👍🏼👍🏼 Awesome explanations I have a 91YJ wrangler 4 L, I’m starting to build back up. Wasn’t even sure what I had in the rear end, now I do. I feel so damn educated now!!! awesome thanks again
Thank you so much for this video, I just got a 1985 Toyota pickup with 33" tires and the guy I bought it from change the gears and wrote it on the door pillar, I had no clue what it was, but now I know, you explain it in such an easy way to understand, thank you so much.
do some videos of your yj
+Nathan Harvested I'm working on some YJ vids. So many projects, so little time... But stay tuned- they ARE coming!
Tyler Bleepinjeep please tell me your work address
wow I would run at least a 4:10 with 33 inch tires
This knowledge is Gold! Thx man. Especially for someone that wants to get a Jeep soon
honestly had no idea how to match gear rations to tire size or even knew that it mattered what gear ratios you match with tire size before this. was just gonna slap some new tires on my truck. super helpful now i know to change gear ratio for best performance & best mileage.
I am so thinking about this because of the mods my Taco is always searching for gears? I'm not a Jeep guy but great video! voodoobluetacolife19
In theory you could run 2 different gears like 4:56 and 4:88 as long as you tire sizes match to the gearing for instance if your wanting to run 35 front and 37 rear or 35/40's or 37/40's, I got s friend who's building a 4x4 69 Camaro and is running 33's front and 44 rears with the proper gear setup to not blow his transfercases, transmission, or anything else.
Excellent video. Incredibly informative. Thanks for making this.
This video is very helpful and is very well explained, thank you guys a lot.
