Transfer Case or AWD Clunking - CLUNK, CLUNK, CLUNK

[Beartoothweb]

Not the one that happens when you put it in gear or decelerate.

I have a 07 Denali XL. About 10k miles ago, it started doing this CLUNK CLUNK CLUNK thing under heavy acceleration, and it's getting worse.

I took it by a transmission shop to have him listen to it, and without opening it up, he seemed to think I'm getting some sort of chain/gear slipping.

Transmission is fine, shifts fine, other wise runs great. It's literally only under heavy acceleration that I get this. If i drive mildly, it won't do it, but as soon as I gas it a bit, it happens.

Would that even make sense about the chain slipping? Is there such a thing in this setup? I'm more of a hot rod guy, so this advanced AWD system is a bit new.

Anyone else experienced this, and/or fixed it themselves? Should I just head to the shop? I have all the tools and a lift and all that, so i don't mind doing it, assuming parts can be had and I can figure out what the crap it is. Thanks!

buy a master rebuild kit and get to wrenching.

Have you a link?

Master "what" rebuild kit, transfer case?

 

[ezdaar]

yea, the "master" rebuild kit. it tells all other rebuild kits how to do their job...
Rebuilding the transfer case.

Stupid question, but where's the easiest place to find the transmission code so I order the right parts?

glove box, RPO code. or the tag on the X-fer case itself.
