Upper Arm Removal/Installation
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 wheels.
3. Place a floor jack under the trailing arm, and support the suspension.
4. Remove the wheel sensor harness bracket (A) from the upper arm (B).

NOTE: Use a new bracket on reassembly.





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

NOTE: During installation, insert the new lock pin as shown after tightening the nut.





6. Disconnect the upper arm ball joint from the knuckle using the ball joint remover.
7. Remove the flange bolts (A) and nuts (B), and remove the upper arm (C).





8. Install the upper arm in the reverse order of removal, and note these items:
^ First install all the suspension components and lightly tighten the bolts and nuts, then raise the suspension to load it with the vehicle's weight before fully tightening the bolts and nuts to the specified torque values.
^ Tighten all the mounting hardware to the specified torque values.
^ Be careful not to damage the ball joint boot when installing the knuckle.
^ Before connecting the ball joint to the knuckle, degrease the threaded section and tapered portion of the ball joint pin, the connecting hole, and the threaded section and mating surface of the castle nut.
^ 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 surfaces of the brake disc/drum and the inside of the wheel.
^ Check the wheel alignment, and adjust it if necessary.
