  2.  
  3. Remove the rear tires and wheels.
  4.  
  5. Use a utility stand in order to support the rear axle.
  6.  
  7. Remove the rear axle coil springs, the spring seats and the spring insulators.
  8.

    NOTE
    Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.


    NOTE
    This is a prevailing torque type fastener. This fastener may be reused only if:



    The fastener and its counterpart are clean and free from rust
     
    The fastener develops 37 inch lbs. (4 Nm) of torque/drag against its counterpart prior to the fastener seating.
     

  6.  
  7. If the fastener does not meet these criteria, replace the fastener.
  8.  
  9. Install the control arm nuts, and tighten the control arm nuts to 162 ft. lbs. (220 Nm).
