REMOVAL

WARNING: The floor lack must remain under the control arm spring seat during removal and installation to retain the spring and control arm in position or personal injury may result.

NOTE: Raise the front of the vehicle and support the lower control arm with floor stands. Since the weight of the vehicle is used to relieve the spring tension on the upper control arm, the floor stands must be positioned between the spring seats and the ball joints of the lower control arms for maximum leverage.





Remove or disconnect the following:
1. Tire and wheel assembly.
2. Air cleaner extension, if required.
3. Brake hose bracket (86).
a. Nuts (85) and screws (87).
b. Tie the hose out of the way.
4. Upper ball joint from the steering knuckle.
5. Upper control arm attaching bolts (79) and nuts (80).
6. Upper control arm (42).
7. Bushings (84).
8. Inspect All parts for wear and damage.

INSTALLATION

CAUTION: 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.

Install or connect the following:
1. Bushings (84).
2. Upper control arm (42) to the frame.
3. Bolts (79) and new nuts (80).
