Removal & Installation
Before servicing the vehicle, refer to the Precautions section.
CAUTIONSuspension fasteners are critical parts because they affect the performance of vital components and systems and their failure can result in major service expense. A new part with the same part number must be installed if installation is necessary. Do not use a new part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.
NOTEThe suspension upper arm bushings or ball joints are not serviced separately from the upper rear suspension arm. If the bushings or ball joints require service a new suspension upper arm must be installed.
- Remove the hub cap. Measure the distance from the center of the hub to the lip of the fender with the vehicle in a level, static ground position.
- Remove the rear wheels.
- Unclip the wheel speed sensor wire retainer from the suspension upper arm.
Remove the speed sensor bolt and the sensor. Position the sensor aside.
CAUTIONUse care not to damage the Anti-lock Brake System (ABS) sensor ring. A damaged sensor ring will result in incorrect ABS operation.
NOTEUse the hex holding feature to prevent the ball joint from turning while removing the nut.
- Remove and discard the upper ball joint-to-wheel knuckle nut, then disconnect the upper ball joint from the wheel knuckle.
- Remove the suspension upper arm-to-subframe nuts and bolts. Discard the nuts and bolts.
- Remove the suspension upper arm.
Install the suspension upper arm, install new upper arm-to-subframe nuts and bolts. Do not tighten at this time.
NOTEInstall the ball joint-to-wheel knuckle nut using the hex holding feature until snug. Final tighten the nut using a line-type crow's foot and a torque wrench.
- Connect the ball joint to the wheel knuckle and hub assembly. Install a new ball joint-to-wheel knuckle nut and tighten to 66 ft. lbs. (90 Nm).
- Clip the speed sensor wire to the suspension upper arm.
- Position a jack stand under the suspension lower arm and raise the suspension until the distance between the center of the hub and the lip of the fender is equal to the measurement taken prior to removal.
- Tighten the suspension upper arm nuts to 66 ft. lbs. (90 Nm).
- Lower the suspension and remove the jack stand.
