Removal & Installation
- Before servicing the vehicle, refer to the Precautions Section.
- Raise and safely support the vehicle.
- Remove the rear wheel and tire assemblies from the vehicle.
- Remove the shock absorber clevis bracket to rear knuckle attaching bolt and nut on both sides of the vehicle.
- Remove the muffler support bracket from the rear frame rail.
- Remove the rear exhaust pipe hanger bracket from the rear suspension crossmember. Let exhaust system drop down as far as possible.
- If the vehicle is equipped with antilock brakes, remove the routing clips for the wheel speed sensor cable from the brackets on both upper control arms.
- If the vehicle is equipped with antilock brakes, remove the bolts and wheel speed sensor heads from both rear knuckles.
- Remove the rear disc brake calipers from the knuckles and hang them out of way using a wire or cord. Do not allow the calipers to hang by the brake hoses.
- Release the brake tubing from the clips on top of the crossmember.
On the side of the vehicle requiring the control arm removal, separate the control arm ball joint from the rear knuckle using following procedure:
- Back off the nut retaining the upper control arm ball joint to the knuckle until the nut is even with the end of the stud. This action will help avoid damaging the stud threads when the stud is released from the knuckle in the following step.
- Remove the ball joint stud from the knuckle using a puller.
- Remove the nut retaining the upper control arm ball joint to the knuckle.
- Position a transaxle jack and a wooden block under the center of the rear suspension crossmember to support and lower the crossmember during removal.
Remove the 4 bolts attaching the rear suspension crossmember to the rear frame rails.
WARNINGWhen lowering the rear suspension crossmember, do not put a strain on the rear brake flex hoses.
- Lower the rear suspension crossmember far enough to access the upper control arm pivot bar to crossmember attaching bolts.
- Remove the 2 bolts attaching the upper control arm to the rear suspension crossmember.
- Remove the upper control arm from the rear suspension crossmember.
- Transfer any required components to the replacement control arm.
- Align the pivot bar on the upper control arm with the mounting holes in the rear suspension crossmember. Install the pivot bar attaching bolts. Tighten the 2 pivot bar attaching bolts to 80 ft. lbs. (108 Nm).
- Using a transaxle jack, raise the rear suspension crossmember up to the rear frame rails and loosely install the 4 attaching bolts.
- Position an appropriate size drift into the positioning hole in each side of rear suspension crossmember and crossmember locating holes in the frame rails of the vehicle. This is required to properly position the rear suspension crossmember to the body of the vehicle.
- Tighten the 4 crossmember to frame rail attaching bolts to 80 ft. lbs. (108 Nm).
- Remove the drifts from the rear suspension crossmember.
- Remove the transaxle jack supporting the rear suspension crossmember.
- Install the upper ball joint stud in the knuckle. Install and tighten the ball joint stud nut to 20 ft. lbs. (27 Nm).
- Install the brake tubing above the rear suspension crossmember into the routing clips on top of the crossmember.
- Install the rear brake calipers onto the rear knuckles.
- If the vehicle is equipped with antilock brakes, attach the wheel speed sensor heads to both rear knuckles. Tighten the sensor mounting bolts to 75 inch lbs. (8 Nm).
- If the vehicle is equipped with antilock brakes, install the routing clips for the wheel speed sensor cables onto the brackets on both upper control arms. Securely tighten the routing clip attaching bolts.
- Install the muffler support bracket on the rear frame rail.
- Install the rear exhaust pipe hanger on the rear suspension crossmember.
- Install the shock absorber clevis brackets on the rear knuckles. Tighten the shock absorber mounting bolts to 70 ft. lbs. (95 Nm).
- Install the wheel and tire assembly on the vehicle. Progressively tighten the wheel mounting nuts in crisscross sequence until all the nuts are torqued to half specification. Then repeat the tightening sequence to the full specified torque of 100 ft. lbs. (136 Nm).
- Lower the vehicle.
- Check the rear wheel camber and toe. Make adjustments to the alignment as necessary.
