REMOVAL PROCEDURE
^ Tools Required:
- J 24319-01 Universal Steering Linkage Puller

1. Raise and support the vehicle so that the control arm hangs freely.
2. Remove the tire and wheel assemblies. Refer to WHEEL REMOVAL.
3. Support the control arm with a jack stand.





4. Remove the ELC air tube from the shock.
5. Remove the two bolts securing the shock to the control arm.





6. Remove the cotter pin and the slotted hex nut.

NOTICE: When separating a linkage joint, DO NOT try to disengage the joint by driving a wedge between the joint and the attached part. Seal Damage may result.

INSTALLATION PROCEDURE
1. Install the jounce bumper by inserting the retainer into the body of the vehicle.
2. Install the spring and the lower insulator. Ensure that the insulator is seated in the control arm.

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.
