I am having trouble diagnosing a problem with my Atlas. After the fluid warms up, it will grind while going down the highway. I replaced the U-Joints in my rear driveshaft, and the noise wasn't as prevelant, but it is still there. It gets really bad when free-wheeling. I pulled the inspection cover off of the bottom and all of the bearings looked in very good shape. The unit only has about 2k miles on it. My rear driveshaft angle is nearly ideal. I never had any trouble with it until I rotated it flat, then the noise appeared. I also took my carpet out at the same time, and I have wondered if it was there the whole time and I could not hear it. Anyone have any ideas?
Thanks-
