Front Suspension - Rear Wheel Drive (RWD)

Upper Arm













Removal

NOTICE: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part numbers or equivalent parts, if replacement is necessary. Do not use a replacement 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.

1. Measure the distance from the center of the hub to the lip of the fender with the vehicle in a level, static ground position (curb height).





2. Remove the shock absorber and spring assembly. For additional information, refer to Shock Absorber and Spring Assembly Front Suspension.

3. Remove and discard the upper ball joint nut.

4. Using the Ball Joint Separator, separate the upper ball joint from the wheel knuckle.





5. Remove the upper arm-to-frame nuts and bolts and the upper arm.
- Discard the nuts and bolts.

Installation

1. NOTE: Do not tighten the nuts at this time.

Position the upper arm and loosely install the new upper arm-to-frame bolts and nuts.

2. Install the shock absorber and spring assembly. For additional information, refer to Shock Absorber and Spring Assembly Front Suspension.

3. Position the ball joint into the wheel knuckle and install the new upper ball joint nut.
- Tighten to 115 Nm (85 lb-ft).

4. Use a suitable jack to raise the suspension until the distance between the center of the hub and the lip of the fender is equal to the measurement taken in Step 1 (curb height).





5. Tighten the upper arm-to-frame nuts to 150 Nm (111 lb-ft).
