Transfer Case Bearings?
I have a 2002 PSD - auto tranny, selector 4wd.
There is grinding noise that is getting worse that appears to be coming from my transfer case. It only happens when I switch to 4wd with my hubs locked. We went through the entire front end already - hubs, all u-joints, wheel bearings, needle bearings, differential, and driveshaft - everything was okay.
When I push on the accelerator it starts up (very loud and it can be felt in the floor) - if I let off and coast, it almost entirely goes away. It is not there at all in 2wd with or without my hubs locked. Are there bearings that normally go bad in the transfer case? Any help is appreciated.
