Thank you for this information. This wheel and suspension stuff on the srt6 is all new to me. Sounds like I will need to get the alignment checked on the rear wheels.

I too am surprised that tires would need to be (partially) replaced, and wheel bearings replaced, with such low mileage. The car has been driven infrequently and gently, well cared for, and mostly parked in the garage. Maybe that could be a part of the problem. The car was never driven much, and just sat for too long.
