REMOVAL & INSTALLATION



See Figures 1 and 2

This procedure requires the use of special tools to properly compress the spring for removal. Do NOT attempt this procedure without the proper tools!

  1. Raise and support the vehicle safely. Position the supports so the front suspension hangs freely.
  2.  
  3. Remove both front tire and wheel assemblies.
  4.  

Do not use corrosive cleaning agents, engine degreasers or solvents near the fiberglass front spring, or extensive damage could occur to the spring assembly.

  1. For 1988-96 vehicles, perform the following:
    1. Unfasten the retaining nuts and bolts, then disconnect both shock absorbers from the lower control arms.
    2.  
    3. Remove the nuts and bolts, then disconnect the stabilizer shaft links from both lower control arms.
    4.  

  2.  
  3. If equipped with ABS, detach the wheel speed sensor electrical connectors, then remove the speed sensor wire from the bracket.
  4.  
  5. Remove the spring protectors.
  6.  
  7. Compress the front leaf springs using tool J-33432 and adapters J-33432-88 or a suitable equivalent tool, then compress the spring.
  8.  
  9. Disconnect the lower control arms from the steering knuckles by separating the ball joints from the knuckle bores.
  10.  
  11. Remove the spring retainer nuts and retainers, then carefully release the spring compression and remove the tools.

  6.  
  7. Install both lower control arm ball stud washers and nuts. Tighten the hex nut to 50 ft. lbs. (68 Nm), then insert a new cotter pin. If necessary tighten the nut additionally in order to insert the pin, but do not exceed a total torque of 88 ft. lbs. (120 Nm) and do not back off the original torque.
  8.  
  9. Install the cotter pins from the rear to the front of the vehicle.

  18.  
  19. If removed, connect both shock absorbers to the lower control arms and tighten the lower mounting nuts to 19 ft. lbs. (26 Nm).
  20.  
  21. Use jackstands to hold the suspension at proper trim height, then tighten the spring retainer nuts to 46 ft. lbs. (63 Nm) and the stabilizer shaft link nuts to 33 ft. lbs. (45 Nm).
  22.  
  23. Remove the jackstand supports, then install the tire and wheel assemblies.
