PRELIMINARY INSPECTION
WARNING:
Always adjust the alignm ent with the vehicle on a flat su rface. Use CONSULT-III “EXHAUST SOLE-
NOID” active test to release the air pressure from the rear load leveling air suspension system.
NOTE:
If alignment is out of specificat ion, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for runout and damage.
4. Check the wheel bearing axial end play.
5. Check the shock absorbers. Refer to RSU-6, "On-Vehicle Inspection and Service"
.
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the rear suspension member for any damage.
8. Check the vehicle height. Refer to RSU-29, "Wheel Alignment (Unladen
*1)" .

REAR SUSPENSION MEMBER
 When raising the rear suspension member assembly, use thelocating 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 fitt ing. 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 final tightening of nuts and bolts for the links (rubber bushing) under unladen condition (unladen condition means that the fuel tank, engine coolant and l ubricants are at the full specification, and the spare
tire, jack, hand tools, and mats are in their designated positions) with the tires on level ground.
 Check the wheel alignment. Refer to RSU-6, "Wheel AlignmentInspection"
