Removal and Installation

CAUTION: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure can result in major service expense. A new part with the same part number or an equivalent part must be installed, if installation is necessary. Do not use a part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct detention 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. With the vehicle in NEUTRAL, position it on a hoist.
3. Using a suitable jack support the lower control arm near the lower ball joint.
4. Remove and discard the upper ball joint nut.
^ To install, tighten to 55 Nm (41 ft. lbs.).

5. CAUTION: Do not use a hammer to separate the ball joint from the wheel 1nuckle or damage to the wheel knuckle can result.

CAUTION: Do not damage the ball joint boot while installing the special tool.





Using the special tool, separate the upper ball joint from the wheel knuckle.





6. Using a plastic tie strap, support the suspension at the wheel knuckle.
7. Remove the 2 upper arm bolts and flag nuts and the upper arm.
^ To install, tighten to 150 Nm (111 ft. lbs.) at curb height.

8. CAUTION: Before tightening any suspension bushing fasteners, use a suitable back 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).

To install, reverse the removal procedure.
^ Check and, if necessary, align the front end.
