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. Insulator (187), spacer (176), and retainer (188) on the support crossmember (175).
2. Support crossmember assembly (175) on the frame, rearward of the mounting holes.
3. Torsion bars (182).
- Make sure the bars (182) are on their respective sides.
- Slide the support crossmember (175) forward until the torsion bars (182) are supported.
4. Adjustment arms (186) on the torsion bars (182).
5. Bolts (178, 180, and 181) and nuts (177, 179, and 189) into the torsion bar support crossmember (175).
- Tighten center nut (189) to 24 Nm (18 ft. lbs.).
- Tighten edge nuts (177 and 179) to 62 Nm (46 ft. lbs.).
6. Adjustment retainer plate (185) and bolt (184) on both torsion bars.
- Increase the tension on the torsion bar, using J 36202.
- Install the retaining plate and the adjustment bolt.
- Set the adjustment bolt to the marked setting.
- Release the tension on the torsion bar until the load is taken up by the adjustment bolt.
