SHOCK ABSORBERPFP:56210
Removal and Installation EES001HJ
REMOVAL
1. Remove the wheel and tire assembly using power tool. Refer to WT-7, "Rotation" .
2. Use CONSULT-II “EXHAUST SOLENOID ” active test to release the air pressure from the rear load level-
ing air suspension system.
3. Remove the four clips and remove the rear fender protector, front.
4. Disconnect the rear load leveling air suspension hose from the shock absorber.

To disconnect the hose, push in on the lock ring using a suit-
able tool and pull the air hose out.
5. Remove the shock absorber upper and lower end bolts using power tool.
6. Remove the shock absorber.
CAUTION:
Do not damage the rubber boot on the shock absorber.
INSTALLATION
Installation is in the reverse order of removal.

Tighten the shock absorber bolts to specification. Refer to RSU-26, "Components" .
INSPECTION AFTER INSTALLATION

Check the shock absorber for any air leaks or damage to the rubber boot.

Check the shock absorber for smooth operation through a full stroke, both compression and extension.

Check piston rod for cracks, deformation or other damage and replace if necessary.

Check the ball joint. Replace the suspension arm assembly if
any of the following conditions exist:
–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-26, "Components" .

Perform the final tightening of the nuts and bolts for the links (rubber bushing) under unladen condition
(unladen condition means that the fuel tank, engine coolant and lubricants 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-28, "Wheel Alignment Inspection" .
Swinging force “A” : Refer to
RSU-48, "

FRONT LOWER LINKPFP:55110
Removal and InstallationEES001HL
REMOVAL
1. Remove the wheel and tire assembly using power tool.
2. Use CONSULT-II "EXHAUST SOLENOID" active test to release the air pressure from the rear load level-
ing air suspension system.
3. Remove the shock absorber lower end bolt.
4. Remove the adjusting bolt and nut, and the bolt and nut, from the front lower link and rear suspension member using power
tool.
5. Remove the front lower link pinch bolt and nut on the knuckle side using power tool.
6. Disconnect the front lower link from the knuckle using a soft hammer.
CAUTION:
Do not damage the ball joint with the soft hammer.
7. Remove the front lower link.
INSPECTION AFTER REMOVAL

Check the front lower link and bushing for any deformation, crack, or damage. Replace if necessary.

Check the rubber bushing for damage, cracks and deformation. Replace the front lower link and bushing if
necessary.

Before checking, turn the ball joint at least 10 revolutions so that the ball joint is properly broken in.

Check the ball joint. Replace the front lower link if any of the fol-
lowing conditions exist:
–Ball stud is worn.
–Joint is hard to swing.
–Play in axial direction is excessive.

Removal and Installation EES001HM
REMOVAL
1. Remove the wheel and tire assembly using power tool. Refer to WT-7, "Rotation" .
2. Use CONSULT-II "EXHAUST SOLENOID" active test to release the air pressure from the rear load level- ing air suspension system.
3. For removing the LH rear lower link and coil spring, remove the height sensor arm bracket bolt from the LH rear lower link.
4. Set a suitable jack to relieve the coil spring tension from the rear lower link.
WARNING:
Do not compress the coil spring when setting the jack.
5. Loosen the rear lower link adjusting bolt and nut connected to the rear suspension member, using power tool.
6. Remove the rear lower link bolt and nut from the knuckle using power tool.
7. Slowly lower the suitable jack to release the coil spring tension. Then remove the upper rubber seat, coil spring, and lower rubber seat from the rear lower link.
