CAUTION: Prior to bushing installation, inspect the bushing to make sure it is the correct side bushing for the job. Left side bushings have the travel limiter (1) tipped to the right in relationship to the bushing (4) can flange as shown in illustration. Right side bushings have the travel limiter (2) tipped to the left in relationship to the bushing (3) can flange as shown in illustration. Once installed, the travel limiters with face slightly outward from straight-ahead position.
CAUTION: It is very important that bushing be installed in same position as original to maintain vehicle ride quality and bushing longevity. That is why bushing, once installed, needs to closely match reference marks applied upon removal of original bushing.
  1. Position bushing on crossmember bushing bore aligning bushing can flange with reference marks applied during removal.

    2 - MARKER (OR CRAYON)
    3 - CROSSMEMBER BUSHING FLANGE
  22. Shift crossmember as necessary to line up mounts (3) with location marks drawn on body (1) before removal.
    Fig 16: Measuring Tension Link Clearance

  23. Once mounts are lined up with location marks, on both sides of vehicle, measure distance (1) between the tension link (2) and weld flange (3) on body directly in front of it, just outboard of the front mount bushing (4). This distance must be at least 12 mm to allow proper clearance for suspension movement.  If distance is less than 12 mm on either side of vehicle, shift that side of rear crossmember directly rearward until distance is 12 mm or greater. To do so, loosen 3 mounting bolts slightly, leaving one on opposite side of shift snugged to pivot off of. Shift crossmember rearward and snug loosened bolts. Remeasure opposite side to be sure it still maintains minimum 12 mm distance.
