To make this short - I just replaced all rubber parts in rear end and shocks and springs. Raised car 1inch. Immediately noise started from rear. Took to dealer - reputable. Replaced rear bearings on driver's side. Noise lessened. Mechanic said pinion bearing making noise and left rear brake caliper piston sticking badly. I pulled rotors and they are deeply grooved, pads ok, parking brake shoes are shot. I planned to get caliper rebuild kit, rotors, pads pkng shoes, and new brake hoses.

Could this be mostly brake noise I am hearing or pinion noise? Did car riding too low for too long cause pinion to wear uneven and now that is raised - to start noise? Changed fluid - put in straight 90 weight. No difference in noise.

Which differentials will fit a W126 1982 300SD? I found a diff with 60k miles but the owner said his car was a 116 chasis 1980 300sd but the part # off diff he gave was 1233510101 and my dealer said part # is no good. He wanted $100 plus shipping of $150. It was on ebay, nobody bid on it. Nice guy but ...

Any suggestions? Thanks.
