  4.  
  5. Remove the 30mm circlip.
  6.  
  7. Remove the torsion bar cap and the torsion bar clip by tapping the bar out of the torque tube. The torsion bar will slide easier by moving the lower arm up and down.

  9. Remove the torque tube.
  10.  

To install:
  1. Inspect the torsion bar for cracks and/or damage; replace it if necessary.
  2.  
  3. Install a new seal onto the torque tube. Coat the torque tube seal and tube with grease, install them on the rear beam.
  4.  
  5. Grease the ends of the torsion bar and insert into the torque tube from the rear.
  6.  
  7. Align the projection on the torque tube splines with the cutout in the torsion bar splines and insert the torsion bar approximately 0.394 in. (10mm). The torsion bar will slide easier if the lower arm is moved up and down.
  8.  
  9. Install the torsion bar clip, the cap, the 30mm circlip and the torque tube cap.
  10.  

Push the torsion bar forward so there is no clearance between the torque tube and the 30mm circlip.

  1. Measure the torsion bar spring height between the ground and the highest point of the wheel arch. The measurement should be 25.7 in. (653mm).
  2.  
  3. If the spring height does not meet the specification above, make the following adjustment.
    1. Raise and support the vehicle with the front wheels hanging.
    2.  
    3. Adjust the spring height by turning the height adjusting nut. Tightening the nut raises the height and loosening the nut lowers the height.
    4.  

  4.  

The height varies 0.20 in. (5mm)/revolution of the adjusting nut.

  1. Lower the front wheels to the ground, then roll and bounce the vehicle up and down several times and recheck the spring height to make sure it is within specifications.
