ADJUSTMENT PROCEDURE

Important: When adjusting either the right or left hand rear trim height the opposite side trim height will be effected.

1. Place vehicle on an alignment rack.
2. Set the tire air pressure to the proper pressure.
3. Manually lift the rear of the vehicle up approximately 38 mm (1 1/2 in) gently remove hands and let the vehicle settle.
4. Repeat the above step two more times for a total of three times.





5. Use tool J 42B54 to measure the distance between the lowest point of the left rear ball joint (2) and the center of the front of the forward rear lower control arm bushing mounting bolt (1).
6. Manually push the rear of the vehicle down approximately 38 mm (1 1/2 inch). Gently remove hands and let the vehicle rise on it's own.
7. Repeat the above step two more times for a total of three times.

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 system.

- Tighten the spring bolt to 50 mm (37 ft. lbs.).

Important: Do not exceed the maximum difference between the right and left rear spring stud heights.
