REMOVAL & INSTALLATION




CAUTION
The spring is under a great deal of tension! It's best to use a coil spring compressor when removing the spring. Mishandling the spring could cause it to fly out of its mounting, causing a great deal of personal damage!

  1. Raise and support the van under the frame rails. The control arms should hang free.
  2.  
  3. Disconnect the shock absorber at the lower end and move it aside. Disconnect the stabilizer bar (if any) from the lower control arm.
  4.  
  5. Support the cross-shaft with a jack and install a spring compressor or chain the spring to the control arm as a safety precaution.
  6.  
  7. Raise and jack to remove the tension from the lower control arm cross-shaft and remove the 2 U-bolts securing the cross-shaft to the crossmember.
  8.  

The cross-shaft and lower control arms keeps the coil spring compressed. Use care when you lower the assembly.

  1. Slowly release the jack and lower the control arm until the spring can be removed. Be sure that all compression is relieved from the spring.
  2.  
  3. Remove the spring.
  4.  
  5. To install, position the spring on the control arm and jack it into position. Use the spring compressor again as a precaution.
  6.  
  7. Position the control arm cross-shaft on the crossmember and install the U-bolts. Be sure that the front indexing hole in the cross-shaft is aligned with the crossmember attaching saddle stud.
  8.  
  9. Further installation is the reverse of removal. Have the front suspension alignment checked.
