Special Tools Required
Ball joint remover, 32 mm 07MAC-SLOA102

1. Raise the rear of the vehicle, and support it with safety stands in the proper locations.
2. Remove the rear wheel.
3. Position a floor jack at the connecting point of lower arm B and the knuckle.





4. Remove the lock pin (A) from the upper arm ball joint (B), and loosen the nut (C).

NOTE: During installation, install the lock pin after tightening the new castle nut.





5. Disconnect the upper arm ball joint from the knuckle using the ball joint remover.
6. Remove the flange bolt (A), then remove the upper arm (B) from the vehicle.

NOTE: During installation, install a new flange bolt.





7. Install the upper arm in the reverse order of removal, and note these items:

^ First install all the components and lightly tighten the flange bolt and the castle nut, then raise the suspension to load it with the vehicle's weight before fully tightening to the specified torque values.
^ Be careful not to damage the ball joint boot when installing the knuckle.
^ Torque the castle nut to the lower torque specification, then tighten it only far enough to align the slot with the ball joint pin hole. Do not align the castle nut by loosening it.
^ Before installing the wheel, clean the mating surface of the brake disc and the inside of the wheel.
^ Check the wheel alignment, and adjust if necessary.
