Vehicle Ride Height

FRONT WHEEL ALIGNMENT









1. MEASURE VEHICLE HEIGHT

COIL SUSPENSION

Vehicle height

When tire radius is 308 mm (12.12 in)

Measuring point:





Front: Measure from the ground to the center of the lower suspension arm mounting bolt.

Rear: Measure from the ground to the center of the lower suspention arm No.2 mounting bolt.

NOTICE: Before inspecting the wheel alignment, adjust the vehicle height to specification. If the vehicle height is not within the standard, try to adjust it by pushing down on or lifting the body.

AIR SUSPENSION:
(a) Bounce the vehicle up and down several times to stabilize the suspension.
(b) Move the vehicle forward and backward by pushing it to settle the tires.
(c) Place the shift lever in the N range.
(d) Release the parking brake.

NOTICE: Block the wheels to keep the vehicle from rolling.

(e) Start the engine.
(f) 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.

(g) Measure the vehicle height.

Vehicle height

When tire radius is 308 mm (12.12 in.):





Left-right error 10 mm (0.39 in.) or less
Hf = Hr = 27.5 (15 mm) (1.08 +/- 0.59 in.)
Hf = Measured value of the front vehicle height
Hr = Measured value of the rear vehicle height









Measuring point:
Front: Measure from the ground to the center of the lower suspension arm mounting bolt.
Rear: Measure from the ground to the center of the lower suspention arm No.2 mounting bolt.

NOTICE: Before inspecting the wheel alignment, adjust the vehicle height to specification.

If the vehicle height is not standard, adjust it by turning the height control sensor link.





2. INSTALL CAMBER - CASTER - KINGPIN GAUGE ONTO WHEEL ALIGNMENT TESTER
Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION





If the steering axis inclination is not as specified, after camber and caster have correctly adjusted, recheck the steering knuckle, front wheel for bearing or looseness.









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