1. Raise the rear of the vehicle, and support it with safety stands in the proper locations. See: Wheels and Tires/Vehicle Lifting/Service and Repair
2. Remove the rear wheels.
3. Place a floor jack under the trailing arm, and support the suspension.
4. Remove the wheel speed sensor bracket (A) from the upper arm (B).
NOTE: Use a new wheel speed sensor bracket on reassembly.
5. Remove the lock pin (A) from the upper arm ball joint, and loosen the castle nut (B).
NOTE: During installation, insert the lock pin as shown after tightening a new castle nut.
6. Disconnect the upper arm ball joint from the knuckle using the ball joint remover. See: Ball Joint/Service and Repair/Ball Joint Removal
7. Remove the flange bolts (A) and the self-locking nuts (B), and remove the upper arm (C).
NOTE: Use new flange bolts and new self-locking nuts during reassembly.
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.
-
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 the tapered portion of the ball joint pin, the connecting hole,
and the threaded section and the 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.
