Longitudinal Torsion Bar Front Suspension

Fig. 4 Longitudinal torsion bar & lower control arm:

This suspension, consists of two torsion bar springs (right and left), two sets of upper and lower control arms, four ball joints and two struts.
The front ends of the torsion bar springs engage the lower control arms at the inner pivot points. The rear end of the torsion bars engage adjustable anchor and cam assemblies that are supported by brackets welded to the frame side rails and a removable crossmember.
The upper control arms are mounted on removable brackets that are bolted to the frame side rails. The lower control arms are attached to the frame front crossmember by a pivot shaft and bushing assembly.
The pivot shafts are mounted in replaceable rubber bushings.
The steering knuckles are connected to the upper and lower control arms by means of ball joints. To prevent the possibility of fore and aft movement of the lower control arms, a strut is attached to the front crossmember and to the lower control arm.
This suspension has a rubber mounted crossmember, a torsion bar crossmember, more serviceable struts and a lower control arm with pressed in ball joints. Caster and camber settings are made by loosening the upper control arm pivot bar bolt nuts and adjusting as necessary.
