Upper Arm Replacement

Special Tools Required
Ball joint remover, 32 mm 07MAC-SL0A102

1. Raise the rear of the vehicle, and support it with safety stands in the proper locations.
2. Remove the rear wheel.
3. Remove the rear damper/spring.
4. Remove the brake caliper bracket mounting bolts (A), then remove the caliper assembly (B) from the knuckle. To prevent damage to the caliper assembly or brake hose, use a short piece of wire to hang the caliper assembly from the undercarriage. Do not twist the brake hose excessively.

NOTE: Make sure the washers position on reassembly, if they are removed.





5. Remove the lock pin (A) from the upper arm ball joint, then remove the castle nut (B).

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





6. Disconnect the upper arm ball joint from the knuckle using the ball joint remover.

NOTE:
^ Be careful not to damage the ball joint boot when installing the remover.
^ During installation, to connect the ball joint, position a floor jack under connecting point of the knuckle and lower arm A, and raise the suspension with the jack.





7. Remove the wheel speed sensor harness bracket (A).





8. Remove the upper arm mounting bolts (A), and remove the upper arm (B).

NOTE: Use new mounting bolts during reassembly.





9. Install the upper arm in the reverse order of removal, and note these items;
^ First install all the components, and lightly tighten the bolts and nuts, 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 connecting the knuckle.
^ Before connecting the ball joint, degrease the threaded section and tapered portion of the ball joint pin, the ball joint 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.
^ After installing the brake caliper, make sure the clearance between lower arm B and the parking brake cable is more then 5 mm (3/16 in.).
^ Before installing the wheel, clean the mating surfaces on the brake disc and the inside of the wheel.
^ Check the wheel alignment, and adjust it if necessary.
