Have problems with a rough, jarring ride and shift clunking on my 2005 2.8L. I'm seriously considering replacing all the bushings on the car. What do I get? My preference goes to OEM replacement wherever possible but I understand that there are some bushings that Cadillac does not provide separately, but only as part of an assembly; the rear trailing arm is one. In these cases I am certainly amenable to RevShift, for instance.

Does anyone have a comprehensive list of all suspension/drivetrain bushings?
