Clunk in rear.
Noise in front suspension.
These problems have been with the car since we bought it. It has been back to dealer 5 times and they are now telling us it is a common problem called drive line lash. There telling us that this problem cannot be fixed.
My 1999 Yukon Denali did the same thing not long after I purchased it new. After repeated complaints, the dealer finally called the factory and they determined that the transfer case had "sticky gears". To correct the problem they had to drain the transfer case and refill it (supposedly repeating the process several times).
It appeared to get rid of the problem for the past 3 years.
Now if I can only figure out why the ABS wants to engage only when going very very slowly. Yours might do the same soon.
I had a similar problem with my 1998 almost since new had it back to dealer 3 times each time they greased CV joints and another time replaced CV boots and 3rd time said that they didn't hear clunk noise. A good friend of mine own's a auto parts store he climed under the truck and had me put it in gear and he felt very strong that it was the transmission mound. I put up with the clunk until 11-12-03 and with close to 100K on it traded it in on a new 2003 Tahoe. This one now has 23K on it and I am having trouble with it not taking the gas. When I cruise and come to a slight up grade it doesn't pick up speed it starts to vibrate the truck as if the front wheels are on a wash board.
