Differential Bushing Installation
Note: Bushings supplied with these arms are designed to be used with the original differential bushing shells. Do not press
out bushing shells.
1.
Remove the rubber and the inner sleeve from the outer bushing shells and clean the original shells thoroughly.
2.
Using the supplied grease, lube the inside and flange of the O.E. bushing shell.
3.
Lightly grease the inside and outside of the polyurethane bushing and install bushing into shell.
4.
Grease the outside of the steel sleeve and insert it into the polyurethane bushing.
5.
Install the thrust bushing.
Installation of QA1 Adjustable Trailing Arms
Note: QA1 Adjustable trailing arms are fully assembled, greased and
ready to install.
1.
Install the new trailing arms with the grease fittings facing down,
locating the front bolt first.
2.
Place one drop of blue Loctite™ on clean threads and torque the
nut to 70 lb.ft. The trailing arm should pivot smoothly.
3.
Pivot the trailing arm into position over the polyurethane bushing
and thrust washer. Install the rear trailing arm bolt in same
direction as the original.
4.
Place one drop of blue Loctite™ on clean threads and torque the nut to 70 lb.ft.
5.
Although QA1 Trailing Arms are pre-lubed, you may want to finish your installation by lubing the front bushings with a
grease gun. Be sure to replace the dust caps on the zerk fittings to prevent dirt and corrosion from damaging the fitting.
Notes:
1.
QA1 Adjustable Trailing arms come pre-adjusted to stock length. Pinion angle can be adjusted by loosening the jam nuts
on the arms and turning the aluminum adjuster sleeve in the center of the arm. Both arms should be adjusted evenly. A
properly installed and adjusted trailing arm will have the spherical ball straight and parallel with the ball housing. If the
ball is twisted in its housing when installed, the arm could fail during suspension articulation. After adjustment has been
made, use a drop of Loctite™ on threads at jam nuts.
2.
Re-torque all bolts after the first 10 miles and jam nuts should be checked periodically for tightness.
