If the vehicle height is not within the standard, try to adjust it by pushing down on or lifting the body.

MEASURE VEHICLE HEIGHT 

1. Bounce the vehicle up and down several times to stabilize the suspension.
2. Move the vehicle forward and backward by pushing it to settle the wheels.
3. Place the shift lever in the N range.
4. Release the parking brake.
   NOTE: Block the wheels to keep the vehicle from rolling.
5. Start the engine.
6. Set the height control switch in the HIGH position, then after waiting 1 minute with the vehicle height in the raised condition, set the switch in the NORM position to lower the vehicle s height.

   Wait 50 seconds with it in this condition. Repeat this operation one more.

   HINT:

   Be sure to perform this operation 2 times so that each suspension part settles down.

7. When the radius of a tire is 315 mm (12.40 in.) or 318 mm (12.52 in.) vehicle height will be the value described in Fig 5.

If the toe-in is not within the specification, adjust it at the tie rod end.

HINT:

• After adjusting the camber, inspect the caster and toe-in.
• Try to adjust the camber to the center value.

1. Loosen the camber adjusting cam nut.
2. Turn the camber adjusting cam and adjust camber.

   HINT:

   Camber changes about 6 18" (0.11°) with each graduation of the cam.

3. Torque the camber adjusting cam.

Torque: 172 N.m (1,755 kgf.cm, 127 ft.lbf) 

HINT:

The caster can be adjusted by replacing the No. 2 bushing bracket.

1. Jack up the vehicle and make the wheels in full rebound condition.
2. Remove the nut and washer from the rear of the lower No. 2 bushing.
3. Remove the bolts from the right and left sides of the lower No. 2 bushing bracket and take out the bracket from the lower arm.
