Alignment: Service and Repair
Height Measurement

HEIGHT MEASUREMENT

The vehicle suspension height MUST be measured and adjusted before performing wheel alignment procedure. Also when front suspension components
have been replaced. This measure must be performed with the vehicle supporting it's own weight and taken on both sides of the vehicle.

NOTE: Vehicle should have a full tank of fuel prior to measuring and adjusting alignment.

FRONT RIDE HEIGHT MEASUREMENT

1.   Inspect tires and set to correct pressure.
2.   Jounce the front of the vehicle.
3.   With vehicle on level ground or hoist, make the following measurements:

a.   Front wheel spindle (center) to ground vertical distance.
b.   Center of the front face of bolt on the rear leg of Lower control arm to ground vertical distance.
c.   Difference between spindle and control arm bolt to ground distances should be 81mm+/-3.2mm Note that the control arm bolt is lower than

the spindle.

4.   If adjustment is required, turn the torsion bar adjuster bolts- if lowering ride height, unscrew Torsion bar adjuster bolt beyond desired point so as

to set height when screwing-in adjuster bolt.

5.   After making any ride height adjustment, roll vehicle preferably jouncing it also, to relieve camber Effects and then re-measure Lower control arm

bolt to ground height.

6.   Repeat the previous steps until the ride height is within specifications.

REAR RIDE HEIGHT MEASUREMENT

1.   Inspect tires and set to correct pressure.
2.   Jounce the front of the vehicle.
3.   With vehicle on level ground or hoist, make the following measurements:

a.   Distance from the landing pad of the jounce bumper on the axle side to the jounce bumper cup lip of the frame side.
b.   The difference between the jounce bumper landing pad and the jounce bumper cup lip. The reading should be 148 mm +/-10 mm for 9.25"

axle, 154 mm +/-10 mm for 8.25" axle.
