INSTALLATION
Installation is in the reverse order of removal.
When raising the rear suspension member assembly, use the
locating pins to align the rear suspension member to the vehicle
body.
When installing the upper and lower rubber seats for the rear
coil springs, the arrow embossed on the rubber seats must point
out toward the wheel and tire assembly.
To connect the rear load leveling air suspension hoses, the lock
ring must be fully seated in the fitting. Insert the hose “B” into the
lock ring “A” until the lock ring “A” is touching the hose “B” as
shown. Pull on the hose to check that it is securely inserted.
Perform the final tightening of the nuts and bolts for the links (rubber bushing) under unladen condition
with the tires on level ground.
Check the wheel alignment. Refer to RSU-47, "Wheel Alignment" .
