REMOVAL & INSTALLATION



See Figure 1

  1. Jack up car and support so that front suspension hangs at full rebound.
  2.  
  3. Remove adjusting bolt from both torsion bar locknuts.
  4.  
  5. Install torsion bar remover and installer tool on torsion bar crossmember.
  6.  
  7. Tighten center bolt of tool until adjusting arm is raised high enough to permit removal of locknut. Remove locknut.
  8.  
  9. Repeat Steps 3 and 4 on other side of crossmember.
  10.  
  11. Remove parking brake cable guide at right side of underbody.
  12.  
  13. Remove torsion bar crossmember bolts and retainers from both sides. On 1974-76 models, remove the lock pins and retainers from either end of the crossmember.
  14.  
  15. Move crossmember toward side opposite the torsion bar being removed. One side of crossmember should clear frame at this point.
  16.  
  17. Lower the free end on the crossmember and drive it rearward until torsion bar is free. It may be necessary to loosen parking brake adjuster nut to gain slack in cable.
  18.  

Although both torsion bars can be removed at this point, it is usually much easier to remove/install only one side at a time.

  1. Remove torsion bar from lower control arm.
  2.  

Nicks or scratches in the torsion bar can cause its failure.

To install:
  1. Lubricate 3 in. (76mm) of each torsion bar end. Bars are marked L or R for left and right sides - do not interchange.
  2.  
  3. Slide torsion bar into lower control arm as far as it will go after installing the torsion bar seal.
  4.  
  5. Position adjusting arm in crossmember. Holding arm in place, slide torsion bar rearward until it is seated in adjusting arm. The torsion bars are stamped L for left and R for right. The stamped end is installed in the lower control arm.
  6.  
  7. Position crossmember to frame, then reverse the balance of the removal procedure.
  8.
