    1. Raise the jack to remove the tension from the lower control arm pivot bolts.
    2.  
    3. Install a chain around the spring and through the control arm as a safety measure.

During removal, note the direction in which the pivot bolts are mounted.

  1. When all of the compression is removed from the spring, remove the safety chain and the spring.
