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.
4. Adjust the spring height between the top surface of the axle jounce pad (3) and the bottom surface of the frame jounce bracket (6).
