- Riding height is adjusted by changing the angle between trailing arm center line and markings on outer bracket. See Figure. The trailing arm and outer bracket have full serrations around the torsion bar mounting hole, while torsion bar has 1 missing serration, thus allowing torsion bar to be inserted at any angle.
- To increase riding height, turn outer end and inner end of torsion bar in direction opposite to cast-in arrow on outer end of bar. Height changes 0.20" (5 mm) with each shift in serration.
- Initially set vehicle rear riding height by inserting torsion bar with its missing serrations aligned with markings on outer bracket surface and trailing arm inner surface. This should equal the approximate riding height. See Riding Height Specifications chart .
- Measure riding height from center of trailing arm bushing to ground and determine numbers of teeth to be shifted on inner and/or outer serrations.
NOTE:
Vehicle must be in unloaded condition.
- At top of shock absorber, remove bolt attaching shock to body. Raise rear of vehicle and remove wheel. Remove lock bolt of outer bushing. Remove 3 bolts connecting outer and inner arms with brake drum supported by a jack to prevent brake hose damage.
- Place alignment mark on outer bushing, crossmember and torsion bar for reassembly reference. Measure vertical distance between end of outer arm and vehicle body. Pull out outer arm and torsion bar until inner serration is completely disengaged.

- Rotate torsion bar and outer arm to shift matching of inner serration by appropriate pitches and engage inner serration with crossmember. Pull outer arm from torsion bar and rotate outer arm in opposite direction to shift matching of outer serration by appropriate pitches.
NOTE:
DO NOT disengage inner serration of torsion bar from crossmember.
- Install outer arm to torsion bar and crossmember, then measure vertical distance between end of outer arm and vehicle body. Change in this distance shows half of change in riding height clearance caused by adjustment.
- Install 3 bolts connecting outer and inner arms. Repeat adjustment procedure on opposite wheel. Install wheels and lower vehicle. Install shock absorbers and outer bushing lock bolt. Check rear riding height adjustment. If correct, tighten lock bolt on outer bushing. If incorrect, repeat adjustment on each wheel.
