Do not lubricate bolt/nut threads.
Use a 1” drive impact wrench
to tighten pivot bolt until the
Torx

head is sheared off.
Failure to install and maintain suspension component fasteners at torque specifications could result in
suspension failure and void the warranty. Refer to the engineering drawing for torque values.
Disassemble suspension
Remove wheels and tires, if necessary. Remove pivot
hardware and alignment plate. Inspect the alignment
plate and repair/replace, as needed. Discard pivot
hardware (new hardware and wear washers are in-
cluded in the bushing replacement kit).
Rotate trailing arm beams down and out of the hang-
ers. Inspect the pivot bolt holes and the hanger sur-
faces for unusual wear or damage. Repair or replace
components, as needed.
Bushing Removal
Bushing Replacement Tool-6100044
1. Lubricate the threads of the hex nut-threaded rod
assembly, the inside threads of the plunger, and
the end cap bearing with grease.
2. Assemble the bushing replacement tool and place
on the eye of the beam (Figure 8).
NOTE: Cone is tapered inside to a smaller opening
on one end.
2.1 Place the end cap on the hex nut-threaded rod
assembly. The end cap should be seated on the
flange of the hex nut. Place the larger opening
of the cone against the end cap.
2.2 Insert the threaded rod through the bushing
sleeve and center the tapered end of the cone
on the beam eye.
2.3 Thread the plunger onto the threaded rod.
Rotate the plunger until the plate is seated
snugly against the bushing.
3. Use a 3/4” drive impact wrench on the hex nut to
rotate the threaded rod and press the bushing out
of the beam eye into the cone.
NOTE: A small amount of heat may be required to
break the bond between the bushing and the beam
eye. Do not overheat. Allow beam to cool before
installing the new bushing.
4. Disassemble the bushing replacement tool. Re-
move old bushing from the cone and discard.
Bushing Replacement Procedure
Park the vehicle on a level surface. Chock wheels to keep vehicle from moving. Raise vehicle to height that
removes load from suspension and support with jack stands. Disconnect the linkage from the height control
valve(s), if equipped. Exhaust all air from the air system.
Failure to properly chock wheels, exhaust the air system and safely support the vehicle could allow
vehicle/suspension movement that could result in serious injury.
Figure 8.
The tapered end of cone allows bushing to ex-
pand during removal.
