Upper Control Arm Replacement
REMOVAL PROCEDURECAUTION: Floor jack must remain under the control arm spring seat during removal and installation to retain the spring and 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.
3. Remove the ABS wire and the brake hose bracket from the upper control arm.
Important: Support the Rotor assembly in order to prevent the rotor weight from damaging the brake hose.
4. Remove the upper ball joint from the steering knuckle.
5. Remove the attaching bolts and nuts from the upper control arm. Note the location of any shims.
6. Remove the upper control arm.
7. Inspect all of the parts for wear and damage.
INSTALLATION PROCEDURE
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: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.
4. Install the nuts.
^ Tighten the nuts with the front suspension loaded.
^ Tighten the nuts to 115 Nm (85 ft. lbs.).
5. Install the upper ball joint to the steering knuckle. Refer to UPPER BALL JOINT REPLACEMENT (RWD).
6. Remove the temporary support from the hub assembly.
7. Install the ABS wire and the brake hose bracket to the upper control arm.
8. Install the tire and wheel assembly.
2G9. Check the front wheel alignment.
