For vehicles equipped with a torsion bar suspension, turn the bolt (1) that contacts the torsion arm as needed. One revolution of the bolt (1) into the nut, increases the Z height by approximately 6.0 mm (0.2 in).
For vehicles without torsion bars replace damaged or worn components as necessary.
If these measurements are still out of specifications after adjustment or are not equipped with torsion bars, inspect for the following conditions:
- Sagging front suspension. Refer to FRONT COIL SPRINGS REPLACEMENT or TORSION BAR AND SUPPORT ASSEMBLY REPLACEMENT in Front Suspension.
- Collision damage
