Chris---Before you replace your trailing arm bushings, measure the wheel
base. From the center of the front wheel hub to the center of the rear
wheel hub it should measure 88 inches. Large differences (more than 3/16
inch) can cause the car to crab down the road. A different number of
shims at the brackets can be a clue, as well as an odd combination of
bracket choices.
You won't go wrong with the harder rubber trailing arm bushings, altho I
like the urethane, to keep rear wheel steering to a minimum. All of
these poly-type bushings need a good coating of moly grease on them
before installing, to keep the squeaks at bay.
