Fig. Fig. 3 Make sure that you position the bushing correctly during installation

  1. Remove the hub cap or wheel cover. Loosen the lug nuts.
  2.  
  3. Block the front wheels. Raise the rear of the car and support it on jackstands. The dimples on the sill flange locate the support point to place the jackstands.
  4.  

Damage to the unit body can result from installing a stand at any other location.

  1. Disconnect the lower mounting nut of the shock absorber.
  2.  
  3. Remove the four U-bolt fastening nuts from the spring seat.
  4.  

It's not necessary to remove the shock absorber; leave the top connected.

  1. Place a floor jack under the rear axle and raise it just enough to remove the load from the springs. Remove the spring pad and seat.
  2.  
  3. Remove the two rear shackle attaching nuts and the rear shackle.
  4.  
  5. Remove the front pin retaining nut. Remove the two pin retaining bolts and take off the pin.
  6.  
  7. Remove the spring.

It is a good safety practice to replace used suspension fasteners with new parts.

To install:

  1. Install the front spring eye bushings from both sides of the eye with the bushing flanges facing out.
  2.  
  3. Insert the spring pin assembly from the body side and fasten it with the bolts. Temporarily tighten the spring pin nut.
  4.  
  5. Install the rear eye bushings in the same manner as the front, insert the shackle pins from the outside of the car, and temporarily tighten the nut after installing the shackle plate.
  6.  
  7. Install the pads on both sides of the spring, aligning the pad center holes with the spring center bolt collar, and then install the spring seat with its center hole through the spring center collar.
  8.  
  9. Attach the assembled spring and spring seat to the axle housing with the axle housing spring center hole meeting the spring center bolt and install the U-bolt nuts. Tighten the nuts to 33-36 ft. lbs.
  10.  
  11. Tighten the lower shock absorber nut to 12-15 ft. lbs. on all models.
  12.  
  13. Lower the car to the floor, jounce it a few times, and then tighten the spring pin and shackle pin nuts to 36-43 ft. lbs.
