Thank you.I was stuck on how to adjust the backlash. You are the only one who showed a tool to adjust the back lash. I made a tool similar to your tool. Thank you, I could not have completed the job without your insights and help. I could not have done it without your video.

[@CFITOMAHAWK]

I bought that tool at Amazon for 29$. Easy.

[@jimbo3214]

Outstanding video. Really helps me understand the backlash adjustment because I am in the middle of rebuilding my 8.25 rear end. Thanks

[@Donnythelatemodeltech]

👍how did it turn out?

[@jimbo3214]

@@Donnythelatemodeltech Great. Thanks

[@danhambrick6331]

Nice job.I made my own side adjusters wrench out of black pipe and an 1.5in. bushing.

[@theequalizersoul]

Amazing video!!! thank you!!! following step by step what you did on my own cherokee xj I was able to fix the backlash of my xj, it went from feeling "slugish" to have a new life, as new, no more noises, no more dragging, nothing, just pure power, just as new. Thank you very much, amazing video.

[@Donnythelatemodeltech]

That's awesome

[@james4wd236]

I've done a few rebuilds on Chevy with shims (basically R&R), but never swapped gears or installed a AFM posi and fully set up a 8.25 or 9.25. I'm about to finally install a new dura-grip posi and do a 3.55 to 4.56 gear swap on my 2000 Dodge Ram. Ever since I put these 35's on its been a dog on acceleration and maintaining highway speed. Thanks for the video's, reassures my confidence to complete a gear swap without issues.

[@CFITOMAHAWK]

Late answer maybe. But the higher the gear, the lower your highway speeds will be due lowr rpm from engine. Your big tires already is equivalent to a big gear diff. Just like funny cars and dragsters. The tires get bigger at higher speeds to preserve high speed rpm.

[@james4wd236]

@@CFITOMAHAWK I got them in. Even did a video on my Chanel about it. It pulls good on the Highway now. Problem with big tires is it lowers the final ratio and therfore at 70 your RPM are low and out of the Powerband. Truck pulls much better and drinks about the same amount of gas.

[@CFITOMAHAWK]

@@james4wd236 Do you have a V6 or V8? With a V8, you will have more low end torque and in power band even at lower rpm than a smaller engine.

[@carterledbetter7657]

So you only tighten the left side then once you get it to where you want it, then that's when you tighten the right side?

[@CFITOMAHAWK]

About 08:38 . I read those bearing cap bolts are 60 pounds of torque, not 100 like here. I put mine 3 months ago at 60 pounds. Right??

[@Roy-xe9is]

So, I torque and preload the right side and then I begin adjusting the left?

[@testosteroneinc.3800]

THANK YOU SIR! I saved this video for future reference

[@MiikeyLawless]

Dumb question: If my diff is howling under load (which indicates too much backlash and not enough lubrication) can I adjust it this way, assuming my ring gears are still good? Just got this old girl and she needs some love.

[@abouscarpetable]

What kind of tool is that your using to adjust the lash in the axle like that!?.

[@Roy-xe9is]

What is the final torque on the screw adjusters after backlash s set?? Thank you!!!

[@SaltyMafugga]

I believe he said 75 ft lbs

[@chrisholmes2888]

hey where u get that long bar that goes in the rear axle hole

[@curtismoore4043]

What kind of tool is being used to ser preload?

[@eduardojdm-cb9un]

on the backlash part, do you have to start on one specific side? or if i want can i torque first the passenger side and i will be good?

[@muhammedmansoor5873]

Good job

[@GLG-20DECOY]

Not sure where you got 100 ft pounds for the bearing caps. Everywhere I’ve looked it’s 60. 😮

[@Donnythelatemodeltech]

Alldata

[@sandysabin2433]

What is the name of the tool used for adjusting the backlash and preloading the bearings? Great video btw.

[@Donnythelatemodeltech]

You mean measure backlash? Dialindicator.

[@joeh5695]

It's called a carrier bearing adjustment tool

[@CFITOMAHAWK]

Amazon has it for 28 $

[@dancrone4200]

I have a question. I am rebuilding a Chrysler 8.25. I had to replace the ring, pinion and all bearings, races. The spec sheet for the pinion depth is .030. (the old shim gone from rear pinion bearing locking up). When I try to crush the sleeve there is still too much play in front pinion bearing. Any suggestions would be appreciated.

[@Donnythelatemodeltech]

It take a lot of torque to crush it. You need a really powerful impact.

[@dancrone4200]

@@Donnythelatemodeltech Thank you.

[@beardedgaming1337]

ive never done a crush sleeve axle. at what point in here do you measure and setup for pinion depth? i didnt see that step or any explanation on this

[@Donnythelatemodeltech]

I've got a few videos on the channel, take a peak

[@beardedgaming1337]

@@Donnythelatemodeltech I finished building the Chrysler 8.25, figured it out. Actually easier than the shim design

[@pandydiy]

Would you be able to assist me on diagnosing my differential whine after replacing pinion bearings and also differential side bearings ? I uploaded a video to my channel

[@Donnythelatemodeltech]

Sorry for the lateness

[@pandydiy]

@@Donnythelatemodeltech I think space between my ring and pinion is too big and I need to bring ring closer

[@pauldolan1493]

From my first attempt at a gm 12 bolt, I had perfect pinion depth, good pattern and I read good backlash but still had some whine. Turned up the stereo for 5000 miles and went back in. Turns out I didn’t squeeze in enough carrier shims. Stuff loosens up. The adjustment feature of the Chrysler 8.25 takes this variable away but still loosens up so I’d guess you’d find excessive wear or initial big backlash if you opened it now. I’ll add that there are some cheaper ring/pinion sets out there that seem soft. Also if you start with big backlash stuff wears fast which makes it worse

[@Sublime3rd]

My guy, you skipped a whole section and start talking about “RECHECK”. WTH man?

[@Me-em9hy]

I feel dumber watching this

[@eduardojdm-cb9un]

dude i was about to assemble everything like "okay this is good enough" and after watching this vid i think my diff is about to explode

[@CFITOMAHAWK]

No, im your father. And you were bobo always...
