REMOVAL
NOTE: Raise the vehicle on a hoist and support the rear axle independently to relieve the tension on the leaf springs.
Remove or disconnect the following:
1. U-bolt nuts (7) and washers (8).
2. Anchor plate (9).
3. U-bolts (10) and spacer (11). Loosen the shackle to spring nut (12).

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. Spring assembly (24) to the vehicle.
2. Spring to front bracket bolt (22), washers (21), and nut (20). Do not tighten.
3. Shackle (18) to rear bracket bolt (17), nut (15), and washers (16). Do not tighten.
4. Spacer (11) and new U-bolts (to) to the top of the spring.
NOTE: Do not re-use old U-bolts.
