Torsion bars must be replaced as a pair and are specific to the left or right side. When working around them, take care not to chip the exterior coating to prevent rust damage. Begin by raising the front of the vehicle and securely supporting it on jackstands, while blocking the rear wheels to allow the front wheels to hang down fully. Work on one side at a time, marking the relationship of the adjuster arm to the rear end of the bar and counting the number of exposed threads on the adjuster bolt. Remove the adjuster bolt, spacer, and nut, then move the torsion bar rearward with the adjustment arm still in position until the front end clears the lower control arm anchor, allowing for removal of the torsion bar and arm. For installation, slide the adjustment arm onto the torsion bar, aligning the splines using the previously made marks. Slip the front end of the bar into the splined anchor in the lower control arm and reinstall the adjuster bolt, spacer, and nut. Tighten the adjuster nut the same number of turns recorded before disassembly. After driving the vehicle to allow the suspension to settle, compare the left and right side ride heights and adjust the torsion bars as necessary by turning the adjuster nuts gradually in the desired direction, rolling the vehicle back and forth a few feet between adjustments, and ensuring that the final adjustment is made as the adjuster nut is lightened, not loosened.
