rear differential mount

Aloha,

My technician has pointed out that the rear differential bushings are bad. The rubber has failed. He claims that this is the reason we hear a chirping noise every now and again from the rear when going over bad pavement or even when closing the doors. I have looked on Subaru parts website but cannot find the parts on any of the rear suspension or rear differential schematics. got any ideas as to what I should be looking for? A part number would be very appreaciated. Also if the rear diff is suspended at an odd angle because of the mounts being bad, would that throw off the allignment? The allignment shop says everything is within factory specs, but she still drifts to the right

Front suspension continues to give me some greif -- new tires, motor mounts, struts, helpers and spring seats are great -- however I still feel every variation in the road. She just does not feel as sure footed as when new -- or even a few years ago. My tech says he will retourque everything in the front to make sure all is tight but after that he is out of ideas. Springs? Stabiliser bars? Other rubber bits to change?

Finally the interior creaks and rattles are getting silly. Anyone had experience with the rubber bits that keep the plastic parts quiet?

Mahalo in advance for your response, much Aloha
