Upper Control Arm Replacement RWD

Caution: Floor jack must remain under the lower control arm during removal and installation to retain the lower control arm in position. Failure to do so could result in personal injury.

1. Raise the front of the vehicle.

•	Support the lower control arm with floor stands.

•	Because the weight of the vehicle is used to relieve the spring tension on the upper control arm, position the floor stands between the spring seats and the ball joints of the lower control arms in order to maintain maximum leverage.

2. Remove the tire and wheel assembly. Refer to Wheel Removal in Tires and Wheels.

Important: Support the rotor assembly in order to prevent the rotor weight from damaging the brake hose.

3. Remove the upper ball joint from the steering knuckle. Refer to Upper Control Arm Ball Joint Replacement .



4. Remove the attaching bolts and nuts from the upper control arm. Note the location of any shims.



5. Remove the upper control arm.
6. Inspect all of the parts for wear and damage.

1. Install the bolts to the frame.




Important: The left upper control arm shaft depression must face inboard.

2. Install the upper control arm to the bolts.
3. Install the shims to the original position.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

4. Install the nuts.

Tighten

•	Tighten the nuts with the front suspension loaded.

•	Tighten the nuts to 75 N·m (55 lb ft).
