Suspension Height Adjustment
The vehicle suspension height should be measured and adjusted (if necessary) before wheel alignment or when front suspension components have been replaced.
The measurement should be made with the vehicle supporting its own weight and taken on both sides of the vehicle.
- Bounce the front end of the vehicle up and down several times.
- Measure and record the distance from the ground to the center of the lower suspension arm rear mounting bolt head. Then, measure and record the distance from the ground to the center of the front wheel.
- Subtract the first measurement from the second. The difference between the two measurements should be 1.85 in. (47mm) plus or minus 0.25 in. (6.4mm).
- Use the torsion bar adjustment bolt to adjust suspension height: turn CW to raise the vehicle; turn CCW to lower the vehicle.
- Carry out the same procedure on the other side of the vehicle.
- Recheck the height on both sides of the vehicle.
