To install:
  1. Assemble the trailing arm and connecting rod. Install the trailing arm to the vehicle and secure in place with the front mounting nuts and bolts. Tighten the nuts snugly at this time. Complete the final tightening of the trailing arm installation bolt when the full weight of the vehicle is on the suspension.
  2.  
  3. Install both control arms to the trailing arm, using new self-locking nuts. Tighten the stud nuts to 52 ft. lbs. (72 Nm).
  4.  
  5. Install the lower shock bolt and tighten to 80 ft. lbs. (110 Nm).
  6.  
  7. On FWD, install the sway bar link. Install the parking brake parts and axle hub unit.
  8.  
  9. On AWD, install the dust shield, axle hub and companion flange with a new self-locking nut. Connect the rear axle to the companion flange.
  10.  
  11. Temporarily install the speed sensor to the knuckle; tighten the bolts only finger-tight.
  12.  
  13. Route the cable correctly and loosely install the clips and retainers. All clips must be in their original position and the sensor cable must not be twisted. Improper installation may cause cable damage and possibly system failure.
  14.  

The wiring in the harness is easily damaged by twisting and flexing. Use the white stripe on the outer insulation to keep the sensor harness properly placed.

  1. Use a brass or other non-magnetic feeler gauge to check the air gap between the tip of the pole piece and the toothed wheel. Correct gap is 0.012-0.035 inch (0.3-0.9mm). Tighten the 2 sensor bracket bolts to 10 ft. lbs. (14 Nm) with the sensor located so the gap is the same at several points on the toothed wheel. If the gap is incorrect, it is likely that the toothed wheel is worn or improperly installed.
  2.  
  3. Install the brake disc, caliper and connect the parking brake cable, if not already done. Install the mounting clamps bolts.
  4.  
  5. Double check everything for correct routing and installation. Lower the vehicle so its full weight is on the floor.
  6.  
  7. Tighten the front trailing arm/spindle assembly mount nuts to 101-116 ft. lbs. (140-160 Nm).
  8.  
  9. Take your vehicle to a suitable repair shop, then have then perform a rear wheel alignment.
