1. Got the rearend whine that peaks at about 60 MPH and seems to go away after that.
2. growling in the rear wheel bearings-I think.

Anybody gotten into that part of the anatomy and are there any traps-tricks etc? I have a lifetime of backyard wrenching and the book so, i don't mind but I don't want to get to the point of no return and find I have made matters worse. I also have a parts car. The 300D parts seem the same. Is a swap appropriatevs. fix?

I have a couple of 300Ds and they have a lot more miles on them and no rearend probs. Why?

Thanks in advance for any advice from anyone who'se been there. Sreve
