2. If equipped with rear load leveling air suspension system, use CONSULT-III “EXHAUST SOLENOID”
active test to release the air pressure from the rear load leveling air suspension system.
3. Set suitable jack to support rear lower link.
4. Remove the shock absorber lower end bolt.
5. Remove stabilizer bar connecting rod from front lower link.
6. Remove stabilizer bar clamps and place bar aside.

FRONT LOWER LINK
 Check ball joint. Replace suspension arm assembly if any of thefollowing exists:
- Ball stud is worn.
- Joint is hard to swing.
- Play in axial direction is excessive.
INSTALLATION
Installation is in the reverse order of removal.
 Tighten the nuts and bolts to specification. Refer to RSU-19, "Removal and Installation"
.
 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"
.
Swinging force “A” : Refer to
RSU-29, "Ball Joint"

Turning force “B” : Refer to RSU-29, "Ball Joint"

Vertical end play “C” : Refer to RSU-29, "Ball Joint"

HEIGHT SENSOR
1. Start the engine.
2. Use CONSULT-III to perform "STANDARD HEIGHT LEVEL" work support function.
3. Using data monitor of CONSULT-III, verify "HEIGT CALC" is at 0 mm.
4. Check the vehicle height. Refer to RSU-30, "Wheelarch Height (Unladen*
1)" . If vehicle height is not
within ± 10 mm (0 ± 0.39 in) of the specification, perform the initialization procedure. Refer to RSU-26,
