REMOVAL & INSTALLATION



See Figures 1, 2 and 3


CAUTION
The coil springs are under a considerable amount of tension. Be extremely careful when removing or installing them; they can exert enough force to cause serious injury. A coil spring compressor is recommended for removal and installation. This tool can usually be rented at tool rental shops.

  1. Jack up the front end of the car, and support the car at the frame with jackstands so the control arms hang free.
  2.  
  3. Remove the shock absorber. Disconnect the stabilizer bar at the steering knuckle.
  4.  
  5. Support the inner end of the control arm with a floor jack.
  6.  
  7. Raise the jack enough to take the tension off the lower control arm pivot bolts.
  8.  
  9. Chain the spring to the lower control arm.
  10.  
  11. Remove first the rear, then the front pivot bolt.
  12.  
  13. Lower the jack, slowly and carefully, until all spring tension is released.
  14.  
  15. Note the way in which the spring is installed in relation to the drain holes on the control arm and remove it.
  16.  

To install:
  1. Position the spring to the control arm and raise it into place.
  2.  
  3. Install the pivot bolts and torque the nuts to 100 ft. lbs. (136 Nm).
  4.  
  5. Replace the shock absorber and stabilizer bar.
  6.
