Good luck! I will use this as my guide.

I think its the same. If you have the AWD Denali I think the only difference is the transfer case.

Got it out and thats all the time I had this weekend. My previous links spell things out OK but I did have some issues pulling it. If you can, disconnect the tie rod shaft so it drops down a bit and you'll save a bunch of time. Not doing that I had to....

- Drained the diff and put the plug back in.
- Really jack up the front end.
- Drop down the passengers side until the pass diff side was pointed straight at the ground. The includes pushing the lower mount point up and clear.
- Then I had to lift up and rotate the diff towards the rear of the truck to clear the top mounting point.
- After fully rotated to the rear I could then clear the cross member with the input shaft point and drop the damn thing.

**** me, what a pain. I hope I get this damn thing done before winter. Oh and since changing the fluid 2 months ago the magnet on the plug was covered with metal shavings. I hope I can salvage this thing and not need to buy a new one.

Split the case with a 10lb slide hammer.

Does this look good?! Perhaps this is adding to the metal shavings.

I had some time to pull bearinigs. Everything is apart except for the pinion. Thats next weekends fun.


I broke this tool so back to Amazon it goes!

Broke riiiiiight here... also some other stuff bent.

Lets try this again! Beefier splitter, 2 prong puller, non marring hammers and an in-lb torque wrench for preload measurements.

With tools and parts I'm $500 into this rebuild. *eye twitch* A new rebuilt unit is $1000ish, so I guess its OK. I suppose these tools will be good for my trans rebuild this winter.

Still....

I'm also eyeing this. The problem is that shipping is over $100. I can pick it up locally but as you might have guessed, I don't exactly have a working truck right now. No way this would fit in my Lexus.

The pinion gear wasn't happening so I took it and the carrier bearings to a shop to be pressed on. I'm not sure the $$ now, but at most $99 (I know, too much) bah.

When I got home tonight I pulled all other races and seals. Then I cleaned up with brake cleaner. I hope all is done this weekend and I didn't end up hurting something.

I scratched the main seal where the pinion shaft goes through. I also nicked where a race goes. I hope this won't cause issues?! Part of the learning process.

A local company (Hi Tech Transmissions) pressed my bearings in. They did a fast and good job. When I was told they were ready I was informed it was free since it was so easy. I picked up pizza and wings as thanks.

^^^ It was these dudes that helped me out. They also have a huge selection of transmissions. I'll be talking to them a bunch, buying parts and whatnot when I start my 4l80e adventure! Oh and they looked at me like I was crazy for doing so much to a 2002 Yukon. I told them I agreed that it was a money pit, but a fun money pit.
