I have a Denali 2007 6.2L engine with Automatic transmission 4WD

Question:  I have this Denali, and it is making a loud clunk, clunk, clunk...sound when under harder acceleration. It was suggested that I need to do a master rebuild kit to fix the problem. Would that be your suggestion, or do you suggest just buying a rebuilt transfer case from you to bolt in. The vehicle has 160k on it now. I'm willing to pay a little more for convenience, but I don't want to spend $1600 if a simple $200 rebuild kit would work.

Answer:   This is a BW4485 transfer case, the problem you describe could be a problem with stretched or worn out chain.   We would suggest you rebuild the unit and purchase the following parts:

• Bearing Overhaul Kit part number TRSBKBK4485 your cost $123.93

• Chain part number MTCCL10-502 is the transfer case chain  your cost $140.00 plus freight.
