Installation Procedure

WARNING: This page is about a different car, the 2002 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: The lower control arm vertical bushing MUST be installed in the same position which it was removed in order to maintain the original vehicle ride, handling and road feel.
  1. Align the flat edge of the bushing flange to the mark in the control arm (1). Ensure that the flat edge of the bushing flange is 30 degrees (2) from the centerline of the lower control arm. Ensure that the thin slot in the bushing is facing outboard.
  2. Insert the bushing into the control arm.
