Thanks for the input. I think taking the cover off the rear end will answer a lot of questions. Going to go ahead and do wheel bearings too, as I am going to Brembo drilled/ slotted rotors along with spring and shock work as soon as I can sort out best way to address castor camber issues on the front end when I lower it with Eibach springs, around 1.2". I meant to spell RPM, not rmp.
