Use the same or equivalent parts if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Tighten fasteners as specified.

Measure the distance from the center of the wheel hub to the lip of the fender with the vehicle in a level, static ground position (curb height).





2. Remove the wheel and tire. REFER to Wheel and Tire .

3. Remove the rear brake disc. REFER to Brake Disc .

4. Using a suitable jackstand, support the lower arm.

NOTE: Before tightening any suspension bushing fasteners, use a jackstand to raise the rear suspension until the distance between the center of the hub and the lip of the fender is equal to the measurement taken in the removal procedure (curb height).
Position the wheel knuckle and loosely install a new lower arm-to-wheel knuckle nut and bolt.

2. Loosely install a new toe link-to-knuckle bolt and nut.

3. Position the wheel speed sensor harness and install the wheel speed sensor and bolt.
