  3. Remove the strut from the vehicle.
  4.  
  5. Install the strut securely in a vise with either aluminum or copper plates to protect the strut.
  6.  
  7. Loosen the piston rod upper nut several turns but DO NOT REMOVE IT.
  8.  
  9. Install the lower end of the strut in the vise and install a coil spring compressor. Compress the coil spring and remove the upper nut.
    CAUTION
    Failure to fully compress the spring and hold it securely can be extremely dangerous.

  10.  
  11. Slowly release the coil spring tension.
  12.  
  13. Remove the suspension support, dust seal, spring seat, spring insulators, coil spring and bumper.
  14.  
  15. While pushing on the piston rod, be sure that the pull stroke is even and that there is no unusual noise or resistance. Also inspect for any oil leakage around the piston rod.
  16.  
  17. Push the piston rod in, then release it. Be sure that the return rate is constant.
