One of, if not THE clearest explanation of a differential I've seen. Great job!!

[@yvindHenriksen]

Thank you for a great video. 😃 You explain very well, and it is easy to understand! 👍 I really like that you link to tools and parts😃

[@kenj.8897]

Very well explained , where did you gain your knowledge from ? Your a lucky guy your partner gives you the freedom to pursue your passions .

[@RepairGeek]

I talk about it here: kzbin.info/www/bejne/fGPSZIWPjKeYd6ssi=SwgrQe7nxrXJimi1&t=922

Thank you so much for this man. I'm wanting to put 4.56s on my 14 5.0 to compensate for 33's. I was worried about setting everything up because I've never done it before but after watching this it looks relatively easy. Also helps im a machinist so it clicks pretty well for me

[@KerryCox1967]

Great video. I am in the process of rebuilding the front differential of my ‘77 FJ40 LandCruiser. This explains much of what I saw on other channels but which was not explained in depth. Great video. Appreciate you taking the time to go over everything in so much detail.

[@richierich1169]

I love this video. I'm glad I kept on searching. Truly the basics as I knew nothing about a differential. But, I never take my vehicle to a shop. I figure it out myself and do the repairs like I have done for years. But this munka sunka has got my brain all twisted up. I have a 2012 Jeep Wrangler. I took it apart because of the racket is was making. I found it needs new carrier bearings. All good, I have got it totally broken down. I've got new bearings and grabbed a small variety of shims. Because her is where my dilemma starts. On the passenger carrier 1 thick shim and 1 thin shim was used. No big deal. On the drivers side instead of any thick shim. The were 8 thin shims that when i removed the cover the shims were sticking down about an inch to an inch and a quarter and of course destroyed. Also the drivers side axel was sticking in the spider gear so far that it was up against the spider gear rod with some force. I looked at the passenger side and i didn't see the spline of the axel at all. When i pulled the bearings off the carrier 1 thin something like a shim was behind the bearing. Just that one bearing. I haven't seen any video at all where there is a shim behind the bearing. If you could give me a little insight to these little issues. I would so greatly appreciate it. It's a dana 44 by the way. Thank you for your time.

[@WayneRiesterer]

Awesome videos! I've gone from knowing hardly anything to a heaps better understanding thanks to you.

[@paulfrankelphd]

This is a great explanation for a beginner. Thank you for helping me.

[@bojo8141]

Great video, your insight is spot on. Thanks for sharing.

[@onemoremisfit]

When you make a large increase in the OD of the tires, the powertrain isn't the only thing that loses leverage. So after you change final drive ratio to regain lost acceleration leverage, you might want to allow more following distance in traffic if you didn't make any brake upgrades to compensate for the leverage the brakes also lost.

[@hansp47d]

This is so very well explained. Good job, well done! Very helpful😊

[@stuffandsuchyeah5182]

Thanks for the insight. I recently had a pinion gear "rub into" and carve out the differential case, but it would only grind on deceleration. Still moves, if you don't coast it doesn't make noise. It's a 1999 chevy suburban that I will most likely be completely replacing the rear end, but I am very curious, what do you think failed to cause this? Been watching all your videos on this and they are gold, thank you.

[@hoosiered471]

Are you still recommending "Surface Shield" as the best of the three for underbody protection in our lovely upper Midwest region????

[@RepairGeek]

Yep.

[@brianhoefer7148]

Regarding speed vs ratios. Tremec has an online gearing calculator. Enter tire size, transmission gear ratios, final drive ratio, and engine rpm, and the calculator will give vehicle speed at the specified rpm for each transmission gear. Example, my 2014 F150 with 3.31:1 final gears on 35x12.5's in 6th gear at redline would mathematically hit 238mph in the vacuum of space. I went with 4.56:1 gears.

Great stuff. You really know your stuff.

[@thesetruths1404]

I've got a 2005 GMC Yukon 5.3L 4x4 with 234,000 miles, all stock. It makes a clicking noise that I can usually only hear with windows down and driving next to something like a wall or tall curb. It only does it when applying gas though, and in a forward gear. I have examined the u-joints and driveshafts and they look fine and tight. It does look original. Do you think this is the issue? Thanks!

[@Wes816]

Fantastic video

[@manikantareddykotha8635]

Great explanation

[@manikantareddykotha8635]

Lower number of pinon gear teeth = Higher gear ratio = faster acceleration

[@jieddo1]

That solves that question. I think I will take it to a mechanic now 😂

[@spiridondimaris465]

Good video importing one well done

[@brownbovel8829]

❤❤❤❤Great information

[@bw6078]

Good information here.

[@roo-jitsu3449]

Great video

[@timsimons8946]

Can crush collar sleeve with shims change pinion depth? First time and everything feels to tight. I think I need to add another shim on the crush collar sleeve. I'm at 20 but it feels just a tad tight with backlash 8 9.

[@BilalHarbi-fl3sy]

Tanks good explination

[@davem3789]

If I am just changing pinion and carrier bearings but keeping the same gears, shouldn't I be able to reuse the original pinion shim?

[@RepairGeek]

Yes.

[@manikantareddykotha8635]

9.51minute - it is mentioned as lower ratio....i think , it is higher gear ratio.. in higher ratio, torque and acceleration will achieve.. can you clarify

[@MrEbanks]

Ok I get it, what driveability issues will all of this cause

[@5000RR]

im about to replace bearings on my W164 mercedes

[@MichaelDespairs]

Nope! Nevermind!

[@AnisleeBibart]

This is fucking impossible

[@Paint75]

Its not, ive been looking at these videos for days and days trying to figure it out and suddenly it clicked for me. It will for you too just keep watching them. It helps to understand what each gear does and that will serve as a hood base to learn stuff like this
