Ride Height

No routine ride height adjustment is provided. Should it be necessary to adjust ride height, the torsion bar(s) must be removed as described in this section. To increase ride height, turn the outer end of the torsion bar in the direction of the arrow (on the end of the bar). Decrease ride height by reversing the above.

Shifting the torsion bar one tooth will alter ride height approximately (0.19 in. (5mm).All 4 wheel drive vehicles have a unique adjusting device that will alter the ride height. (In addition to adjust the torsion bars) refer to rear road clearence for instructions.

Camber is adjusted by changing the number of shims mounted between the inner torsion bar bushing assembly and the body. Each shim corresponds to 1 / 4 ° of change. Adding shims decreases the camber. Removing shims increases it.


WARNING
Camber on 1980-84 models is not adjustable. If any of the rear suspension components become worn or damaged, they must be replaced in order to bring the rear alignment back within specification.
