Man, you just saved me tons of looking for an exploded view of that front diff. My wife's Driver side CV is moving all over and leaking. And now I'm just gonna follow your cue and rebuild the whole thing. Good times 🙄🍻

7:48, I am 65 and "I" have never seen so many expensive things fail like they do now. Your answers to these problems lays on the Corporate share holders meeting room table on Wall Street.

The trick for removing a bearing race from an aluminum housing is to weld around the center of the bearing race. Welding the center, not touching any of the aluminum will shrink the bearing race and it will drop out without any issue. This is the recommended procedure to remove a race from any aluminum housing. If they are pounded out the metal will remove a little aluminum and the new bearings will be loose in your case. Thanks for the video. Improvements would be How to set the backlash and how much torque on the bolts and nuts on install.

Nice video and insight man. Thank you. Great shop you got goin

Need to do mine as well. Great video. Thanks

good rebuild video ...

Sitting on the side of the freeway waiting on the tow truck watching your video because the front differential of my Chevy Tahoe just exploded, lol...

They leak a tiny bit while driving. Sitting still it doesn't leak. I know because the under side has a little wet and there is always a tiny drop on the axles but never a puddle in the garage

True, but it also depend on the situation and the parts you need to cut the bearing off of. I have done bunches the way you descibed.

I have a 2011 Sierra Denali AWD. Something up front is making a slight rhythmic shudder that isn't constant. Maybe last like 1/3 of a second , then fades out and comes again. Its on the drivers side for sure. Checked everything else up front. Fluid was about 2/3 of a quart low. Does this sound like front diff is toast?

Front drive shaft u-joints. Lube or replace it.

Do you gotta drive it around for a couple mins/miles cause I’m sure I did it right. I had to change the seals on the cv axels and the gasket you replaced where the 5 bolts are.. after I filled it up with fluid 2qtr(dealership said 1.5qtr but mine ate two maybe cause I did it on the ground) But after putting it on I went to drive it no sound/clunking/grinding I shifted into 4H no problem(no noise etc) but when I put it on neutral and 4L(it engage normal) and put it on drive it was just revving my rpms and slightly moving.. there still wasn’t no sound/noise/grinding etc any suggestions? Help Thanks

I think that they're all open and use the the awd case to transfer the power. The brakes is what manages the traction control. The rear axle in your rig is more likely a posi style rear differential.

rear is open also, but I think you are right I think it uses the abs to keep traction going.

@@TheLifeofaMan Many upper trim gm body on frame vehicles come with the Eaton g 80 rear axle that acts as an open differential until there is slippage then locks the rear axle. You can check your VIN to varify. My 07 Yukon Denali came with a g 80 rear axle. Some lower trim vehicles may not. All front differentials are open. Aftermarket does offer lockers for the 8.25 front differential. I would suggest a electronic locker such as an Eaton e locker, but it does put a lot of stress on the CV axles, so next you may need to look into upgrading those as well.

As soon as I put mine in gear it starts making a loud noise that looks like the front drive shaft trying to spin. Do you think it is the front differential?

Hard to say without more details. I can say that the center diff is open on these so if you are sitting still and the front shaft is spinning something is broken.

So anyone have a theory why the bearings in these diffs are failing like that? I have been wrenching for decades and have never seen this except when was run dry. I am now looking for ideas what may be going on in the front of my Tahoe. Came across this type of failure in a few videos now. Makes no sense … unless the bearings used were really REALLY poor quality. Hoping that is not the problem with mine.

@TheLifeofaMan

I personally think it is the shock from putting the vehicle in park/drive. There is tons of slope between all the drive axles and the trans so it shocks the front diff every time you shift. The rear gear are much beefyer and it doesn't seem to hurt them

I think it is the slack in the drive train. There is a noticeable clunk on decel and accel. If you take a wheel at the front then turn it there is probably 3-4inch of movement before all the slack is out and the rear wheel starts turning. I think over time it just shocks the bearing races enough the chip then it goes down hill quick.
