  1. Remove the lower shock absorber mount bolt. If the shock is to be replaced, disconnect the upper mount and remove the shock. If the shock is not to be removed, the upper mount may be left connected during spring removal. If only the shock is to be replaced (removal of the spring not required, skip to Step 13 for reinstallation. Refer to Inspection and/or Disposal of Shock Absorbers in the Front Suspension part of this Section.
  2.  
  3. Disconnect the stabilizer bar brackets from the rear axle housing.
  4.  
  5. Disconnect the right shock absorber lower mount.
  6.  
  7. Remove the bolt(s) holding the lateral control arm to the frame.

  9. Very carefully begin to lower the jack holding the axle housing. Use extreme caution not to snap the brake lines and/or parking brake cable.
  10.  
  11. While lowering the axle, remove the coil spring as it loses tension and remove the upper insulators. Once the spring is removed, the bump stop (spring follow) may be unbolted from the frame if desired.
  12.  

To install:
  1. Install the spring follow to the frame if removed, tightening the bolt to 11 ft. lbs. (15 Nm).
  2.  
  3. Install the coil spring and upper insulators. Check the end of the spring; it must be correctly installed against the stopper on the lower mount.
  4.  
  5. Once the spring is in place, jack the axle housing enough to hold it but no more.

CAUTION
Do not compress the spring beyond the point reasonably necessary to hold it in place. Severe injury can occur if the spring comes loose.

  1. Connect the lateral control rod to the frame, inserting the bolt from the front or shock absorber side. Install the nut but do NOT tighten it at this time.
