What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Fless]

The right axle flange is pushed out of the housing. ???

I think you might be on to something here....

 

[Fless]

well, if it doesn't stay in then maybe..... I have heard of them just popping loose before

Worth a try. Hopefully the clip is still okay.

Got the wiring done so the C-shaped led acts as DRL only and also will come on with the park lamps. Just waiting on parts to convert the old drl bulb to a park/turn signal. Then need to decide to move forward with the led projector retrofit.

Yeah I did the same DRL to turn/park mod. What parts did you order? I just used sockets from a spare set of headlights and forced fitted them into the housings. They are keyed differently from the single filament DRL sockets.

Hopefully.
Remember, this diff is noisy and has excessive backlash. I am really tempted to order a reman and drop the whole thing…

what do you think @iamdub

I'm no good here!

The extent of my 4WD experience is swapping CV axles in these trucks or whole axles on Jeeps. Never messed with this part of the system.

Furnace is on in the shop and I am going under it.

The verdict is in. Looks like the cir-clip ate through the washer in the case. Almost seems like a part is missing. Looking up the assembly now. Need parts.

Is it possible that something internal is worn, allowing it to put pressure on the retaining hardware?

 

[George B]

It's supposed to look something like this but I only found one washer. I think the last guy in here had extra parts.
Now to find that part. Any help @915_Tahoe?

EDIT: Ok, looks like 25980219. I guess there was a design change and they only use the one thick one now. Seems like they should have a thrust washer… Now to find one near 53066.

I’ll never go to Wal Mart, can’t stand that store. So many unsettling people in their stores in my part of the woods plus they’re always super crowded.

But Mobil one is dirt cheap there in 5 qt jugs!!!!!

Looks like it got hot from the snap ring riding on the washer/spacer
did the magnet have much metal on it?

No, not a lot.

One thing I noticed was that the CV axle pulled back away from the stub shaft when I unbolted it like the boots were pulling on it. Thats a Cardone axle from RockAuto. That pull, although not very strong is bearing on that snap-ring and washer.

But… the front suspension is at full drop right now. I bet it doesn’t pull when it’s sitting on the ground.

No, not a lot.

That’s what I meant. Typo
