[@heinricheugenvonhelmbrecht6905]

I am a cinematographer and MS in mechanical engineering. You are overperforming in both. Thank you to your Brother!. The best tutorial and best video I have ever watched.

[@Jodeyjoe559]

i never knew about the rag trick to remove the pinion nut, much quicker than setting up the yoke on that tool with bolts . just stick a rag in it and zap it off . thanks Eric for showing us the shortcuts uve learned from all those years of experience

[@darrenjattan4277]

Hey Eric,I'm from Trinidad You're a number auto technician who teaches everyone the tips in every version And that encourages someone to learn and reach in skillful position You can make somebody go beyond destination with qualification Just keep adding modification

[@deckdresser]

Just got done with this nearly same project on my 85 C10 8.5" ten bolt that started July 5. Yours is a 1990 8.6 but is still applicable to an 85 8.5". I watched and re-watched these videos for insight before and during the project. I can't believe how differently my project went. Thanks Eric for your knowledge and guidance including the tool recommendations. For comparison, my project started with not being able to remove the pinion shaft. The locking bolt came out, no problem. Then the hell began. The carrier came out the only way it could- in multiple pieces. four days later and different parts from Summit, I got to drive the upgraded rear end for the first time. SATISFACTION!

[@BCABearings]

Great video! Always nice to see our BCA Bearings in the wild, especially when someone is using the correct tools and procedures to remove and install them.

[@stanatqc]

ETCG is a good source of joy trough any rough day, he's always having fun around and he'll teach you new perks :)

[@michael102387]

I would like to thank you for your work on KZbin. I will model my entire rebuild after your attitude and know how, but I’m limited in my “budget”. I am still going to need that honest guys help, “My Dad”. Thank you for opening up my eyes to the tools and things I need for prep, if affordable or rentable I am going to do all the work myself. I prefer that way. Thank you sir

[@rayj4722]

My truck, a 02 sonoma, has this differential and I thank you because I was stuck at the point of removing the clips I thought of dismantling the whole thing and then decided to look it up on KZbin, oddly enough I have a blazer same year and it’s a straight and simple differential, that one I had no problems changing oil and changing seals, saved me a headache thank you

[@brendonfleming9243]

Finally somebody who actually shows every step and doesn't hoard their knowledge

[@PhaseP1]

Another option to press or heating the bearings is to place the differential core in deep freezer for a few hours which shrinks it.Did that once when I didn't have a press. I had both frozen the differential but also heated up the bearings. The bearings fell down to their places. Heating the bearings has the risk of weakening them if they get too hot, they may loose their hardness and temper. (Wrote the keyboard/weekend warrior) I like the videos!! Also I had applied WD-40 on the differential so that the condensation from cold wouldn't cause rust. That is the risk with freezing it.

[@sarabrown2840]

Only have watched this one video so far , but you describe , and show everything so clear ...I will be watching many more for sure . Great job your flippin awesome !!!!

[@jewllake]

I've driven GM trucks for the past 25 years all with Gov Locks and they are good units. The guys that blow them up are the ones burning rubber and doing side shows or the ones who get stuck in mud or sand and just abuse the truck and push the skinny pedal to the floor. All my trucks, with the exception of 1, have been 4wd and have been able to get out of tough situations with one wheel completely off the ground and the G80 just made me truck on through. I have also been stupid and done a few wicked burnouts and donuts with my G80 and they have held up well. My new 2018 Sierra 4x4 with the 6.2 420 horse and 460 torque has the G80 in it; I'm sure it will be fine. Nice build so far! Have been enjoying the videos, hopefully you don't end up notching the frame.

[@hochhaul]

The newer GM trucks use a modified version of the 14-bolt SF axle. It uses a 9.5/9.75" ring gear and a much bigger carrier. That allowed Eaton to create a beefier G80. They can take more abuse than the older 10-bolt version.

[@kentbarger6974]

I've taken a piece of thick pipe and took out both axle shafts I sent the piece of pipe through the one side of the axle all the way through to the other side pulled up on the piece of pipe which made the other side of the piece of pipe go downward and I hit the piece of pipe and use the pipe to take out the axle shaft bearings I've done this many times it works good for me I'm a retired transmission specialist and Powertrain mechanic had a piece of pipe small enough to go through the bearing all the way through to the other side and use the piece of pipe and a 3lb sledge hammer to knock out the bearing on the other side it may not be the correct tool but it works

[@MrRChitty]

Thank you for taking the time to film this entire video. You helped me a great deal with my pinion bearing replacement. Previous owner drove it too long with a bad u-joint.

Thoroughly enjoyed watching you work ..... you're definitely not the typical hack and slash mechanic

[@markamcampbell6340]

my instructor in mechanics school used to love doing diffs at work. the book gave them 3 hrs and after doing so many of them they could crank them out in 15 to 20 minutes same with brakes it was there bread and butter to them.

[@Nightwing300]

You know how many times I heard guys I worked with say they can do differentials only to have them comeback on tow trucks. I really wanna learn how to do these right. Great video. Hopefully I'll be as good as you.

[@halimaw247]

I don't even have this truck but I still enjoyed watching this video. I like how you explain things.

[@turboflush]

For a honda guy.. You sure seem to know what your doing. Well explained. Been over 20 years since i done one. Getting some refresher.

[@lalosgarage7541]

I did this same rebuild on my 1991 Silverado. Used an Eaton tru trac, Richmond 3.73 gears, Moser axles and rear disc brake kit from Summit. About 2000.00 in parts plus other misc. Came out great, first time I had done a gear set.

[@zacharycopeland9670]

This video is very informative and honest. True trial and error at its finest! You have made a visual representation of engineering vs real world. Thank you

[@Jodeyjoe559]

in school we use a straight thin[1/4"]metal with holes drilled in it on edges, to bolt to diff case in place of cover one or two holes drilled in center of metal for a digital caliper to stick the depth end through a hole to touch pinion, subtract the measurement of piece of metal and thats ur pinion depth

[@ericthecarguy]

I actually cover that in Part 2. Thanks for the comment.

[@Jodeyjoe559]

You have no idea how much you have helped along the way by not only showing real fixes but explaining the operation of what your fixing really helps grasp and retain the information.

[@Cpl.Cadaver]

I re-built the rear end in my s-10 bazer a couple of years ago. I spent as much on tools as I did on parts. Detroit tru-trac, new ring and pinion gear. New axles and bearings all the way around. No regrets with either parts or tools.

Good Camera skill man. You're the David Attenborough of the car world, Awesome info! I have a 66 Chevelle Malibu with a 10 bolt as well, I believe its also 8.5. I was gonna go the 12 bolt route, but funds are not there at the moment But its cool! You have given me the push I needed to rebuild my 10. I'm Rocking a SB 383,550Hp, 530 foot pounds mouse motor. I'm hoping to make this 10 bolt, stout enough for this application. Thanks for the info!

I like the rag trick! That's cool! The carrier caps so u don't mix them up I take a pointed punch and make a dent in the top of one cap and the side it came from do the same on the housing were the gasket touches. Then on the other side I'll put two dents on the top of the cap and same on the housing. Makes it fool proof even if u grind it to clean it the small dent will still be there!! :)

[@davepelfrey3958]

I'm watching this series, getting ready to install a Yukon in my truck. Eric definitely makes it look easy. LoL.

[@simple_fred]

one quick suggestion, when you were using a lady slipper to pop the pinion bearings at time index 8:43. If you stuff a rag into the bear, it reduces the free travel of the loose bear without effecting the impact of the blows to liberate said bearing. These will increase the chances that it's stay within the housing and off the floor. Elsewise, great video for what it is and that you for posting it. Also most people would say a lathe beats a die grind, but oddly a $5 block of dry ice for the local grocery store is far superior to a torch when separating press fit parts because you don't risk changing the crystallographic structure of the steel but effectively annealing the outer part.

[@simple_fred]

I forgot something, tie knot in the rag and pull it in from the far side. My bad.

[@ericthecarguy]

Thanks for the info.

[@throttlebottle5906]

the rag on the wrong side, I caught that as you turned the pinion. at least you left the blooper in there, keeps people awake and paying attention :)

Rebuilt my rear diff on my subaru. 5 bearings 3 seals, and rtv on the rear gasket as I reused it. This is allot easier than that job was.

[@jetjazz05]

Chevy and GM trucks are a joy to work on, replaced a wheel bearing on my father in law's truck, took like half an hour. On my Saab it'd take 2 hours if you knew what you were doing lol.

[@blazetownsend8785]

@@jetjazz05 Some Saab's use a pressfit bearing. I have that on my subaru. Newer versions of the subaru are allot easier, replace the whole assembly in 30 minutes. There are benefits to a press fit style, but it's still a pain.

[@blazetownsend8785]

@@jetjazz05 Oh, and some Saab's use the same pressfit bearing as subaru used to. With the same steering knuckle.... and engine.... ok they were just a newer car using older subaru parts.

[@jetjazz05]

​@@blazetownsend8785 Yeah that's why it takes so long, you've got to disconnect the suspension entirely, break loose the axle nut, remove the control arm from the steering knuckle, slide that all out, disconnect all the mounting hardware for the brake lines, undo the strut tower, remove the plastic shielding in the way, fight with the rusty af mega circlips, deal with awkwardly pressing it out (or risking a slide hammer which never works for me, I end up taking it out every time). Definitely huge time and annoyance benefit to a hub assembly vs pressing a bearing out. Also those were just the major things I can remember specifically about my Saab, but it's an old design from the 90s really, the 2004 and onward Saabs all have the assembly you just bolt in. Somewhere along the line rebuilding lost all priority in vehicles for the sake of quickly and easily replacable assemblies. There's a channel on KZbin, South Main Auto, the guy replaced a bearing in the differential of some Suzuki with 4 wheel drive, the unit itself was 600 dollars and "unservicable", he had to take the dimensions of the bearing and order it that way. Kind of a shame since the rest of the unit was in fine shape that they'd find it cheaper and easier to replace the whole thing for 600 vs disassembly to replace one bearing, but I guess really the hours they'd pay a tech and the potential for something to go wrong just isn't worth it. PLUS that unit wouldn't fail before the warranty ran out lol, so why bother making it serviceable (or so I'm assuming the logic goes unfortunately).

[@blazetownsend8785]

@@jetjazz05 I'll be honest, I do it all with all that still installed. Slide hammer to break free the hub, a bearing install and removal tool that just is a hardened bolt and a large 32 mm nut. You have to go slow though, and it's physically exhausting using a breaker bar to remove and install it. Some use impact wrenches, but I do not like to apply impact to a bearing race.

I really enjoyed this video, Eric! This feels more like the older ETCG videos, and not in a bad way. You seem a lot happier to be doing what you're doing- just working in the shop, goofing off, and being yourself. I can tell something has internally shifted for the better with you, keep it up man!

That can be difficult in and of itself. It took me a long time to figure out that I'm not invincible, and I can't have 8 different project cars going all at once and still be as enthusiastic about wrenching.

The rearend has gone out in my '89 F350 dually. I'm going to open the cover and see what's inside. I can't find a mechanic to work on my truck. It's been over a month. Nobody can get to it. So, I thought I would give it a try. After watching this.....Naaaa. I'll open it and look but, I'll likely just buy a junkyard rearend, huh-to-hub, and replace the whole damn thing. After watching this, there is no way I'm going to buy new guts just to ruin them with my lack of experience and improper tools. Thank you for posting the video and preventing me from making a big mistake.

[@NeverEnoughPyro40]

I had the same Diff in my 05 Silverado Z71 4 x 4! At around 135,000 miles I started hearing a little moan from the rear! So That night I put it up on the lift and removed the cover, I could not believe my eyes! The differential was literally cracked all the way around, Yes it was literally two pieces! I never went off road or towed anything heavy, That diff would always lock and unlock when it was supposed to, But they are not that strong!

My Favorite Tool! A "BFH" Great Video I'm going to do this!

[@93sundance]

19:36 is an example of how NOT to put a bearing separator on the press. By doing it that way you will bend the screws, needs to be rotated 90 degrees so the steel part is bridging the gap.

[@ericthecarguy]

Yea, I saw that too. Sorry.

[@hommie789]

Eric, great in depth video but one small issue, don't tell people they can just weld on the housing. Lots of people do it yes but any manufacturer will tell you there is a preheat and post heat procedure to get a correct weld. So many things effect the weld quality and all those other guys showing they weld with no preheat they never show the diff long term, sure in the bench it looks like a great weld but I can make aluminum look like it is welded to a steel plate too, but doesn't mean it will hold. Also after you file the back of the crown gear a good practise is to go over it with crocus cloth to remove the small file marks, it is so fine it can not and will not hurt just remove the file marks.

[@newls1]

good job eric... 2 things I cant stand the most are working on rearends, and doing drywall!

[@hawkie333]

I hate painting, myself....I’d rather work on a rear end!

[@spelunkerd]

Looking forward to part 2! I've often been curious about how to adjust pinion depth, I've never had the opportunity. There must be an easier way than grinding bearings open to make sure you're in the right ball park, before putting in the real crush washer and a second set of new bearings.

[@graymodeler]

spelunkerd I think the bearing set comes with a figure (distance) to use to set the measurement from the center of the axle races to the rear of the pinion. There is a tool that Eric showed that professional installers use to measure it and install the proper shims. Then the side lash also has to be measured and adjusted with the shims Eric removed with the diff races. Since the teeth are semi circles, they must match.

[@darthvincor]

[@warusweims]

You can brinell a bearing by pressing in the manner that you are. You are correct that you can do that, if you don't overdo it. One can also shrink the bearing onto the shaft. Never heat a tapered roller bearing over 250 degrees Fahrenheit for the purposes of mounting. Over heating any bearing will reduce it's engineered lifespan.

[@jodielee83]

Tip if I may....when looking for something to press bearing onto pinion and can't find a pipe the right size and lenght, cut the cage off of old pinion bearing and remove bearings. This leaves the inner part of bearing. Use this to press on the new bearing.

I had a 69 Gran Prix thar the 428 had been replaced with a older 421. I went through 3 ten bolt difs until I figured out what was going on (that and I was a 19 year old lead foot). I pulled the motor and replaced it with a 400 then bougbt a '67 firebird, a super T10 and a 1:4.88 Dana. The 10 bolt difs went away by: one the axle inner bearing cap cracked in half the other, the spyder gear chowdered and the third one the ring gear cracked. I'm sure that ten bolt diffs are not junk but they don't do well in heavy cars with torquey, long stroke motors that came from the factory to do 13 second 1/4 miles.

Instead of pulling the pinion shim, then trial and error then pinion depth you can measure the thickness differences in the new and old pinion and shim accordingly. Also when checking drag on bearings I’ve had bad luck with install and check, I have found do 2 full rotations and check after.
