To install:
  1. Reassemble the strut assembly and observe the following:
    1. Make sure you assemble the unit with the shock absorber piston rod fully extended.
    2.  
    3. When assembling, take care that the rubber spring seats, both top and bottom, and the spring are positioned in their grooves before releasing the spring.
    4.  

  2.  
  3. Tighten the strut locknut.
  4.  
  5. Install the strut assembly onto the vehicle and tighten the strut-to-body nuts. Tighten the strut-to-knuckle bolts.
  6.  
  7. If equipped with a shock absorber actuator, install the actuator and tighten the actuator-to-plate bolts.
  8.  
  9. If the brake hose was disconnected from the brake caliper, bleed brakes and install the wheel. Reattach the brake hose to the strut.
  10.  
  11. Connect the negative battery cable and engage the adjustable strut electrical connectors, if equipped.
