We are replacing the rear differential components in a Chevrolet Silverado with the 8.6” rear differential. The Chevy Silverado came to us, because it had an issue where differential grinding noises could be heard. We found that the differential pinion nut was loose and made the pinion, and pinion preload very loose. This was why the customer could the grinding and scraping noises inside the differential.

I'm trying to learn from your video if I can do the following thing. I'm buying a used GM IFS7.6 and will disassemble it for inspection. If all races and bearings are good, what steps do I follow to get the pinion back in. Working with a real small budget here. Thanks.

Judging by the dumped glass pack muffler, I'd be willing to bet that diff had a hard life. Lol😊

I have a 06 Silverado 2wd n when I was doing a burn out it made a loud noise n it make a sorta grinding noise when I make left turn mostly what could it be

@axleoffroad 4 месяца назад

Sounds like the differential spider gears are toast or damaged!

@kellismith4329 4 месяца назад

If you are gonna do burnouts you need to build a bulletproof differential none of them will last for that use

@KhrisAllen-jt7qo 3 месяца назад

Well you most definitely tore up the spider gears and are just lucky one wheel is still pulling . U also could have busted something in the tail of transmission

@cdeprima1209 10 месяцев назад

So why not just tighten up pinion nut and shim the carrier left to right to tighten it up, add new gear oil? It did not fail, why replace everything?

@axleoffroad 10 месяцев назад

this customer wanted a complete inspection and rebuild

@andrewcoffman3600 5 месяцев назад

But would what he said fix it without replacing everything? I'm having issues with a whirring grinding noise when I'm rolling into a stop. 2001 silversdo 1500.

@weslevicki3378 4 месяца назад

Im curious about this as well. I have an 04 Silverado z71 and open my rear differential because I suspected the grinding noise was coming form there. It looks the exact same as this one? Could I just tighten the bolt? Since I don't have the time or tools to do this.

@cdeprima1209 3 месяца назад

I say re-shim the setup and get the most out of the hardware! Liberals can do chemo! ;)

@linebackerjs 4 месяца назад

I have a 2016 Sierra and whenever I put it in gear or give it gas a lot of times it slams forward. It seems like it does while shifting gears, but it’s even slammed forward while sitting still like someone rear ended me. I have seen it do it while standing outside of truck also. Any thoughts on this? Could it be the rear end?

@axleoffroad 4 месяца назад

If it slams like that, that’s sounds more like the transmission, But that’s just an opinion based on information given.

@cedricalexander9274 Месяц назад

I have a question I changed all bearings on my rear end and it's still making humming noise idk what it could be.

@axleoffroad Месяц назад

Humming is a noise generated from a bearing. It could be that if the pinion bearing was changed, the pinion nut was over torqued.

@cedricalexander9274 Месяц назад

@axleoffroad ok thanks I'll check that out.

@kb9liq Месяц назад

My GMC 1500 was struck from behind while parked in the garage. Now the right rear wheel is locked up. What did it break? You can jack it up and playing with it get it to turn maybe one turn sometimes before it locks up again

@axleoffroad Месяц назад

Sounds like the spider gears, if it’s an open differential. If you have a traction carrier, it could possibly be the clutches. You really will not know until you remove the cover and drain the oil to inspect. Thanks for commenting! 👍🏼

@kb9liq Месяц назад

@@axleoffroad Moved both sides until they spun free. Drained the oil and opened it. Could not see anything broken, every thing turns fine. took it off the stands and it seems to work like it should. Hate to put it all back together and add new oil only to have somebody say we missed something. It is just a normal rear end for a half ton GMC

@Anthony-du3he 6 месяцев назад

I may have gotten lost in the sauce. The fix was replacing the bearings and races? What about the damage on the gear? I dont know much about diffs so i am generally curious. I have a similar noise and clunk on my truck. Also how much would this repair cost?

@kellismith4329 4 месяца назад

It would cost plenty to have it done at a shop

@benbox7329 3 месяца назад

So I have a 2500 1997 Chevy Silverado it has excessive backlash is it possible to use the shim kit and reshim it to take some of the backlash out without having noise or issues?

@axleoffroad 3 месяца назад

Yes, when done correctly and providing your pinion has the correct preload. you can shim the carrier, set backlash, and confirm the pattern with gear paint.

@letsgoBrandon4200 11 месяцев назад

Awesome video very detailed and easy to follow My opinion is not that loose at all, I'm having a lot of sound coming from my rear end. It sounds like it's my drive line, right? As it goes to the rear, differenti opened up the pumpkin and it was full of metal, but all the gears look to be okay What would you guys normally charge for a job like that that you did on this truck?

@axleoffroad 11 месяцев назад

$650 labor plus parts

@darianthompson5975 2 месяца назад

Could have tighten the nut up a bit? Which companies do you recommend? I have a gm 9.75 3.23 on my 17 escalade

@axleoffroad 2 месяца назад

No, you have to make sure pinion preload is correct.

@rsanchez5179 5 месяцев назад

Thank you very much for your informative video. I have a 2011 Chevy Silverada 1500. When I change gears there is a noise in the differential by the shaft. Also the differential moves upward a little bit when I change gears. Any ideas? Do you think I need to rebuild the whole differential or can it just be a gear box? Thank you again.

@axleoffroad 5 месяцев назад

It’s hard to diagnose without having it in front of me. Is this a 2wd or 4wd? Sounds like it may be something going on with transmission, Or if it’s a 4wd… could be transfer case. Usually you hear a lot of howling, growling, and chatter noises when it’s failing bearings or differential gears, so that could be easy to eliminate with some basic troubleshooting.

@rsanchez5179 5 месяцев назад

@@axleoffroad It is a 2wd. There is a noise when I change gears. The differential moves a bit upward when shifting gears. But no noise at all while driving.

@dravenlively343 5 месяцев назад

My 2013 Silverado had a bad left front wheel bearing, I changed it and now the abs lights on and the left rear tire is locking/skipping when I turn. What is it.

@axleoffroad 5 месяцев назад

Bad ABS sensor, or bearing was not installed correctly. Is it a new sensor? Or did you reused the old one?

I just dropped off my 2007 Chevy Silverado 1500 off at a mechanic shop after reviewing this video I don’t think they have the knowledge to rebuild my differential

@axleoffroad 11 месяцев назад

So what’s the Plan?

@NICK_VERDIN_985 Месяц назад

I have a 2014 chevy Silverado 231k miles I was stuck in mud and as ture spun made a clacking sound but doesn't do it on road is that normal?

@axleoffroad 27 дней назад

Not at all. Sounds like spider gears

@drakko8534 8 месяцев назад

So as of recently my 2015 Silverado has been doing some weird thumps in the rear end I don’t hear anything but when getting up in speed you will kinda feel it thump like something is bouncing around in the bed do you have any ideas what could be going on

@axleoffroad 8 месяцев назад

Could be a number of things. Suspension, you joints, transfer case etc.. bring to a shop

@Skaterjessy019 Месяц назад

What year is this because my suburban 09 looks the same way! And the nut kept coming loose for some reason and now I have issues.

@axleoffroad Месяц назад

Yes! Pinion nut should not be loose! I bet bearing is toast!

@Skaterjessy019 29 дней назад

@@axleoffroadyes this is the second time it does this and there was groves inside the axle like yours.

@tarry863 9 месяцев назад

Been about 25 years since I did a rear end I remember having to get two bearings for the pinion one that you would grind out and slip on so you can put shims when it came to the marking paint you can move it in and out in order to get it to track right then you slap the real bearing on and put it together something like that Tell me what I'm missing...did I miss that in this video?

@axleoffroad 9 месяцев назад

Yep, that’s correct. We use setup bearings as a starting point as described. I have other videos that show this.

@MegaBigDe 10 месяцев назад

To someone that has no idea how to backlash what would you suggest?

@axleoffroad 10 месяцев назад

First of all, you need a good dial indicator with a bracket and magnetic base to attach firmly to the differential chunk. Second you need to look at either the manufacturer specs of the new gear set you’re installing, or the manufacture of the existing gear set. In order to get proper backlash specs, set the dial indicator up against the gear tooth as seen in many of our other videos and check readout. After that adjust the shims by adding on one side and subtracting on the other in order to gain the correct specs. For more information, subscribe and check out our other videos.

Gm differentials last forever when not abused.

@axleoffroad 7 месяцев назад

That, is a false statement and can be misleading to our viewers. We appreciate your opinion, but this statement is untrue. Many things can contribute to issues with a GM differential, when not abused. This includes, but not limited to bearings, seals, gears and other components. This could be a failure in quality control or manufacturing processes. We have worked on many different differentials, and they all had their own story.

@herculesinwyoming 7 месяцев назад

@@axleoffroad matter of opinion. I'm 53 years old and owned many trucks with this differential. Never ever had an issue
