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. 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 wheel and tire.

3. Using a suitable jack support the lower control arm near the lower ball joint.

4. Remove and discard the upper ball joint nut.

5. NOTICE: Do not use a hammer to separate the ball joint from the wheel knuckle or damage to the wheel knuckle can result.

NOTICE: Do not damage the ball joint boot while installing the C-Frame and Screw.

Using the C-Frame and Screw, separate the upper ball joint from the wheel knuckle.





6. Using a plastic tie strap, support the suspension at the wheel knuckle.

Installation

NOTICE: Before tightening any suspension bushing fasteners, 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). This will prevent incorrect clamp load and bushing damage.

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

Position the upper arm and install the 2 new upper arm bolts and flag nuts.

2. Remove the plastic tie strap.

3. Connect the upper ball joint to the wheel knuckle and install the new upper ball joint nut.
