Amazing in-depth content. For a home DIY without fancy tools, got me good pattern and no chatter. Thank you 👍🏾

Wear glasses. Hardened steel can Shatter! Good to hear you say. I'm an Old machinist who took a fragment of tool steel from my lip, and once from the white of my eye, scary. I always use gentle heat when removing bearings. I made a special pinion setup bearing by honing .0005 from the ID of a New BRG to be able to remove it for shim setting. Used it 3 different times for my 12 bolt.

Thank you for the education...got my new gears today !... I've done it before, but what a great refresher course you provided !

people always search for the video they need just for a few key points but never like to watch the long video of something as such detail specific crutial steps of something with not only 1 or two but 4 key steps to a correct problem free setup.. as a kid i was always was around my father building personal cars over the years and actually he currently has a 73 camaro and i have purchased a 78 camaro and bought my wife a 78 camaro and rebuilding both 78s i upgraded to a limited slip eaton style unit as my open diff spider gears were eating my cross shaft pin just on 1 end too many 1 wheel peels and making a clunking sound while driving and the amount of information you have taught ensures i will only have to do this 1 time and not have to open the rear end more than 1 time with correct specifications and less worried of problems or noises due to incorrect installation or placement or incorrect shimming. thanks for making a great informational packed video to learn crutial steps to a proper setup... am actually headed to the garage to finish putting in my LSD differential right now...

5 by 5 loud and clear. Thanks so much for an extensive tutorial and it looks like it would be a joy to utilize all that clean space to get some repair and fab work done.

Holy crap! I feel like for the first time I am not crazy scared to try this myself. My project is to replace my open diff with a posi, keeping the same gears. 1) My pinion was untouched so, now after your lesson, I’m not worried about the pinion depth. And I understand how to verify the pinion preload. Even though it it probably unnecessary. 2) I have the proper tools and now I understand how to measure backlash and more importantly how to adjust it. And you really simplified getting to the appropriate preload on the carrier bearings.

This video is as good as it gets on this subject, great detail & explanation.

Woody Harrelson, I really admired your acting, especially those memorable years on Cheers! It's nice to see that you found such an excellent hobby in your golden years. Keep wrenching!

It’s really nice to see a professional take his time and really go through the steps thank you I feel more confident about redoing my 10 bolt now

Setting up my 8.5. Not one video around does a better of a job explaining the set up as this one right here. Thanks so much

WoW! What a great tutorial for someone who has never even tried to do this myself. I replaced the entire rear end rebuild components. I did it all including a new Differential carrier and watching the details you provided really helped me out alot. THank You SO Much for being so detailed.

Seriously, thank you for this video. I have 5,000 miles on my first engine rebuild (5.3 ls) and the truck needs to be re-geared. Dispite getting the thousand pieces of my engine successfully back in working order, this differential has had me scared. Mostly due to the lack of step by step documentation out there. Most everything on the internet is either "throw it together, use some contact paint, and it SHOULD be good to go" or "take it to a professional it was the worst thing I ever tried". I have a few tools to add to my collection, but it definitely seems like something I can do correctly. Thank you. All the question marks are gone.

I have been a DCJ mechanic for 36 years and felt like i was back in a class room again. Love it. After you master all subjects you only get web classes. I miss the class room. The only time you really need to worry about the coast side pattern is when you are doing reverse rotation front axles in 4x4 trucks. You do a great job of teaching the class and remind me of some of the teachers i have had.

Turn your guillotine 90° so that each red spacer is parallel .... arrrg... you just demonstrated. Recently saw Dave's in Utah made it VERY clear to not stress screw rods. Came here after changing fluid (probably) first time on an 07 trailblazer. It's sloppy, but now has new fluid, seal and drain plug (also known as rear cover!) Your videos have helped me out on past and present cars. I am particular and not content with someone else's 'good enough'. And then half of my small fleet is European and I'm in rural Missouri.

This is an excellent video. I have been drag racing for a lot of years and set up lots of gears for racers and it's always a pleasure to see a video with this much detail. Thank you for uploading such a fine video.

I do the ring gear case setup without the pinon in. When you get the right shims with the carrier in and snug up the caps you are suppose to put a inch pound torque wrench on the ring gear bolt and get a rotation reading between 20 to 25 inch for new bearing and 10 the 15 with used bearings. This is the real way to do it. Note it takes time. After you get that during setup you can take away .002 to .004 on each side to get close to your backlash with the pinon gear in. Then add what you took out to get the proper preload on the carrier and check backlash again. The reason for taking side shims away is to make it easy to take the carrier out several times to get close to your backlash. Also a case spreader helps out a lot for hard to get out stuck carriers. Gm had a tool you put in without shims to get the preload then you took the out and mike each one that gave you the shim pack you needed for each side. I never liked them spreading tools myself. If you have done enough of these use a old pinon bearing and use a flapper tool to make the big bearing close to the shim so you can just tap it on to get your pinon setup. Way to easy to wreck a bearing pressing it on and off to many times. I would take the pinon to the tool and die shop I worked at and put the pinon in the lathe and use fine wet sanding paper to get a tap on bearing fit. Did a lot that way and never had a comeback. That way you could use the same bearing to get the pinon deep right. Final assy just put some red locktite and you was good to go. There are a lot more tricks without spending a fortune on tools. Only good tool I hand was the deep setting tool for aftermarked ring and pinon sets which had the deep marked on the pinon. I always used Richmond gears myself. Back in the day it was Schafer gear sets were the best. Zoom gears were junk back in the day. GM gears are to expensive.

I’m really glad you shared this! I have my gm 8.2 ripped apart and ready for new parts. Your explanation helps a lot!! The initial description of the side preload was a lil confusing at first but the summary at the end helped clear the confusion.

I know have the confidence to do my Gen 3 Viper with new gears, bearings, seals and a OS Giken Superlock LSD. Thank you for this exhaustive tutorial. Well done sir.

I've watched many many videos about the rear differential. I've killed 2 factory differentials. So I'm gonna try to build one. Crazy but I feel way more confident after watching this. Your an awesome teacher. Even threw in some common sense along with some technical. Thank you!

Excellent video!! With the addition of a few tools, I’m much more confident that I can do this. I’ll have to take my time but I’m sure I can do it. Thank you!!

This is the most helpful GM rear end rebuild video on the internet .!!!!!

Truly appreciated! Thanks for the thorough detail on the rebuild.

This was an excellent video, very professional, helpful and thorough with an awesome instructor . I've looked through tons of other videos on this subject and this is by far the best I've seen .I learned quite a bit from watching this . Thanks for the upload 👍.

Thank you and your helper for taking the time out of your day to make such a detailed and informative video. This is extremely valuable and knowledgable information and im very thankful you shared this for others to learn. You guys are great!

Best 2 hours I ever spent here at 4:30am. I'm trying to rebuild my GM 8.2 as we speak! I bought a new posi carrier and bearings, crush sleeve. My original .25 spacers were too tight to use but not by much. At least I know what I'm gonna need in terms of spacers or shims. Thank you for the knowledge and extreme details.

I am glad I bumped into your channel cause I,m in the. Middle of changing my 66 c10 to a posi rearend... thanks for the class. It will be my first rearend job !!!

At 1:41 you answered the preload question that has eluded me. The investigation and correction when things didn't turn out perfect is gold, and the little side-bars of real world tidbits like using the press and the cast iron spacer add credibility AND keep it interesting. Nice work!

Your shop is nice and clean. Our shop is nice but it’s a mess. I’ve never had it organized before and we’ve never used it until recently so you’ve inspired me to get it organized. I’d be embarrassed to have anyone see it. It’s 48x48 with a loft and 16’ walls but I need to finish wiring it and installing lights. I’d like to add a lift so we can store another car and work on things with it. Thanks a million from Washington state. I’m 59 and retired and my son is 23 and acts like he is also retired. We are working on 2 66 Chevelles, a 1970 Monte Carlo and his RX8 so we have plenty of projects. I have the 12 bolt out of the Monte Carlo and have a new posi unit and axles to install so thanks for the help! Pat

Nice work! Your a great instructor and very good at teaching proper methods. I appreciate you

Great video! I'll be doing my first install soon and your discussion of carrier preload will be very useful. It's often glossed over. I'm sure I'll watch this two more times and should be able to attack the job with confidence. Thanks!

Thank you, Best explanation and lesson on the internet! Thank you for your knowledge and time!

This is Jeff from Detroit Michigan, and this video is very helpful....thank you

Awesome video and explanation! Thanks for posting. This made my own carrier and gear swap (to limited slip) super easy.

Always wanted to see a rebuild.

I am that shade tree mechanic, absolutely wonderful in your attention to detail, much more confident in my ability to do this properly after watching this , I've dabbled but this is the sweetness .....if you have any vids on 5.7 chevy engine rebuilding I'd love to have your knowledge in my toolbox , thank you men

Thank you for this tutorial...well explained an I learned something tonight...and as always appreciate when someone is willing to share an teach there knowledge

Amazing video. Thank you so much. Still in process of rebuilding my 1971 Chevelle differential but with 2 manuals and this video I think Ill have the confidence to be able to get this job done. Will leave updated comment when I finish. Thanks again!!!

You are so right it is wonderful when a person takes their time to truly show you what you're doing thumbs up to that man.....!!

This is hands down the best video I've ever come across.

I was always afraid to touch a differential. Only thing more complexed to me is an automatic transmission. This is excellent instruction and information on the GM 10 bolt rear ends. I will be using this as I work on my 94 Camaro. Thank you! From a 68 year old gearhead.

Thank you ! This demonstration is without any doubt the best video instruction on a gm differential rebuilt on uTube. Greatly appreciated

i just found this and was really cool to watch ... Thank you

Awesome video, we appreciate your time and patience. for those learning when time is money. I prefer to use an air hammer for seals ,races , removal. Everything. use with a point punch to drive the pinion out in the dimple. use with a brass rod and hammer head to remove and fine tune races , use with your bearing installer to start and drive bearings. lots of light blows makes short work of it. very little room for error too.

Thank you for an excellent demonstration with practical advice. You have a lot of patience.

Another great video. Thanks. Keep them coming. Around the 24:10 mark I just knew that carrier was coming out.

I have done a few. I ALWAYS reused the pinion shims and they always fit right. I didn't want to mess with perfection..lol Nice video!

Thank you for your axel servicing videos!

Best video I've come across to give in depth details....thanks alot!

Great video with thorough details. Much appreciated

Loud and clear, very impressive shop!

Nice casting stay focused you guys enjoy the detailed assembly practices you provide

Great video - excellent detail and good explanation. Thanks for posting!!

This is the best video I have found. Excellent.

Thanks for this! I am a self taught mechanic and can usually do a good job. But this saved me a bunch of mistakes and accelerated my learning curve.

I always like to watch classroom set up and ideas

Great video Sir. I am aa newbie truck enthusiast, area of focus, axles, this was a very good breakdown and much to learn. Thank you for posting. Subd.cheers

Thank you for the great video. Very professional content and video capture of the whole process.

Awesome video would have loved to see this video a year ago when I did a gear swap. I will be using these techniques to do another gear swap from 4.11 to 4.56 tomorrow. Thanks again for the video please keep them coming.

Just watch this video found it fascinating thank you very much I am a backyard mechanic and appreciate the help

wonderful presentation and the overhead camera is awesome..

Great School! Went through the automative program in the early 90s.

Awesome video, Thanks for the great step by step!!

Great job! Starting the complete overhaul of my Tahoe and really learned a lot. I would have missed a lot if I hadn't seen your tutorial. Thanks!

I have a 09 jk x jeep..I'm regear to 4.88. And am going with yukon with new carrier and spider gears..and of course bearings...I'm going to hone out old bearing for set up..everything you've done has been great..I have some mechanical abilities....

the best set up, process I've watched! Thanks.

A very good tutorial, I feel I could set up a Chevy 10 bolt on my own… with a good shim pack. Thank you for making it available to all!

I'm just watching your video because I'm new at what I'll be doing to upgrade and rebuild my 10bolt GM rear end out of my 94 Pontiac Trans am..

Excellent, excellent video. Good teacher.

By far the best video !! Thank you.

Great sound

Very good quality video. Thanks for this.

Thank you so much for your time. Your a fantastic teacher

I can hear you this is Isai from Edinburg Texas

You explain everything extremely well.

Easy to see and hear looking forward to presentation

I am not a student, but this was very informative. Thank you very much.

Definitely built my confidence

awsome video perfectly understood your concept

Very informative lesson. I now have 0 fear doing my rebuild. I must say although I realize those are for demonstration I cringe when you file parts over open diff.

Fantastic video and explanation. Thank you.

Good to go! Great content.

This guy is awesome. Thank you for all the info.

This is so awesome! Thank you very much!

Really good tutorial going to do my diff will follow instructions thanks fir an informative video 👍

Absolutely outstanding! Exceptional!!! Thank you!

Outstanding video! Thanks! Bravo!!

Excellent instruction! Thank you so much!

Thanks! Great video! It was very helpful

Thank you. I'm in southwest Washington and have a '67 C20 4x4 to restore. The pinion shaft seal is leaking so I have to replace it and the hub seals as well. I also have to replace the seals on the front axle. I cringe when you file those shims over the differential cavity.

I’m super lucky because I have to rebuild my differential but my teacher is going to help me out and he’s been a technician for 20+ years.

Great instructor you are.

Watching from Guyana good work

I am helping my brother do his diff. (Complete rebuild). I have never worked on diffs before but after watching this video a gazillion times I feel I could do this blind folded. 😭😭😭🤣😭😭😭😭

Hello I’m new the channel, and really like it so I’ll be installing new Greer in 1976 caprice rear end

You can use a steering wheel puller on your yoke and pinion, just put two bolts in the ujoint holes and tighten the center of your puller and it will pop right out and you will not have worry about the pinion falling out

This is beautiful!!

Great job easy to understand👌

There is also a 8.2 10 bolt. That came in first gen camaros and firebirds.

Thank you for a great lesson

Great camera work
