A special tool, which can be made at home, will aid in the removal of the torsion bar.

  1. Raise and support the car on jackstands.
  2.  
  3. Loosen the cam locking nut and zero the cam.
  4.  
  5. Remove the shock absorber.

  15. Apply chassis lube to the torsion bar splines and insert it into the lever and arm.
  16.  

Adjust nut A on the torsion bar remover 23 1 / 4 inches for the right arm, or 23 5 / 8 inches for the left arm, prior to torsion bar installation.

  1. Tighten the cam locknut. Remove the tool.
  2.  
  3. Install the shock absorber.

  5. Lower the vehicle and check the ride height. Ride height is the difference between the distance measured from the wheel center to the ground, and the distance measured from the frame to the ground. The difference should be 1 / 16 - 13 / 16 in. Turn the cam adjuster to obtain this height.
