UPDATE: POST #22
So I've replaced both upper and lower control arms with UPR's chrome-moly arms with urethane bushings; the rear differential housing does have the urethane bushings as well but those are getting changed out for replacement OEM style rubber bushings in the next week or two. I'm hoping that helps this issue.
This is a street driven car, no track time, and generally driven pretty easy on the streets.
I can hear what I believe to be the axles turning in the rear end, and it's not quiet. It's a noise that is speed dependant. It's not really a grinding, or a whine, but more of a rubbing sound. Axle bearings and seals are brand new and axles have nearly no pitting or scaring. Fluid is brand new with Motorcraft friction modifier.
Is it normal with urethane control arm bushings to hear an increase in rear end noise in the cabin? Is this just part of having a solid axle RWD car that's 23 years old? Is there anything I can do, or at least anything to reduce the amount of noise transmitted into the cabin?
I hate noises like this...
