Control Arm Bushing: Service and Repair

Upper Arm Bushing













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 part, 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. Mark the rear shock absorber relative to the protective sleeve with the vehicle in a static, level ground position (curb height).





2. With the vehicle in NEUTRAL, position it on a hoist.

3. NOTICE: Do not support the rear axle at the differential housing or damage to the housing may occur.

Using 2 suitable jackstands, support the rear axle.


4. Remove and discard the upper arm-to-upper arm bushing nut and flag bolt.

5. Partially lower the rear axle and, using the Rear Drive Unit Bushing Remover/Installer, Axle Bushing Remover/Installer and Adapter, remove the upper control arm bushing.





Installation

1. Position the new bushing into the rear axle bracket with the voids in the rubber positioned at the top and bottom of the bushing.





2. Using the Rear Drive Unit Bushing Remover/Installer and Axle Bushing Remover/Installer, install the upper control arm bushing.





3. Install the bushing so there is a 12 mm (0.47 in) gap between the bushing flange and the rear axle bracket.





4. Raise the rear axle so the mark made on the rear shock absorber in Removal Step 1 lines up with the protective sleeve.





5. NOTICE: Tighten the upper control arm rear nut with the suspension at curb height or bushing damage and incorrect clamp load may occur.

Install a new upper arm-to-upper arm bushing nut and flag bolt.
