Disassembly & Assembly



  1. Position the strut assembly in the strut coil spring compressor following the manufacturer's instructions and set the lower and upper hooks of the compressor on the coil spring. Position the strut clevis bracket straight outward, away from the compressor.
  2.  
  3. Compress the coil spring until all coil spring tension is removed from the upper mount and bearing.
  4.  
  5. Once the spring is sufficiently compressed, install Strut Nut Wrench, Special Tool 9362, on the strut rod nut. Next, install Strut Shaft Socket, Special Tool 9894, on the end of the strut rod. While holding the strut rod from turning, remove the nut using the strut nut wrench.
  6.  
  7. Remove the clamp (if installed) from the bottom of the coil spring and remove the strut (damper) out through the bottom of the coil spring. The dust shield and jounce bumper will come out with the strut.
  8.  
  9. Remove the lower spring isolator from the strut seat.
  10.  
  11. Slide the dust shield and jounce bumper from the strut rod.
  12.  
  13. Remove the upper mount and bearing from the top of the upper spring seat and isolator.
  14.  
  15. Remove the upper spring seat and isolator from the top of the coil spring.
  16.  
  17. Release the tension from the coil spring by backing off the compressor drive completely. Push back the compressor hooks and remove the coil spring.

To assemble:

  1. Place the coil spring in the spring compressor following the manufacturer's instructions. Before compressing the spring, rotate the spring so the end of the bottom coil is at approximately the 9 o'clock position as viewed from above (or to where the spring was when removed from the compressor). This action will allow the strut (damper) clevis bracket to be positioned outward, away from the compressor once installed.
  2.  
  3. Slowly compress the coil spring until enough room is available for strut assembly reassembly.
  4.  
  5. Install the upper spring seat and isolator on top of the coil spring.
  6.  
  7. Install the bearing and upper mount on top of the upper spring seat and isolator.
  8.  
  9. Install the lower spring isolator on the spring seat on the strut.
  10.  
  11. Slide the dust shield and jounce bumper onto the strut rod.
  12.  
  13. Install the strut up through the bottom of the coil spring and upper spring seat, mount, and bearing until the lower spring seat contacts the lower end of the coil spring. Rotate the strut as necessary until the end of the bottom coil comes in contact with the stop built into the lower spring isolator.

  14.  
  15. While holding the strut in position, install the nut on the end of the strut rod.
  16.  
  17. Install Special Tool 9632 Strut Nut Wrench on the strut rod nut. Next, install Special Tool 9894 Strut Shaft Socket on the end of the strut rod. While holding the strut rod from turning, tighten the strut rod nut to 44 ft. lbs. (60 Nm) using a torque wrench on the end of Special Tool 9362.
  18.  
  19. Slowly release the tension from the coil spring by backing off the compressor drive completely. As the tension is relieved, make sure the upper mount and bearing align properly. Verify the upper mount does not bind when rotated.
  20.  
  21. Remove the strut assembly from the spring compressor.
  22.  
  23. Install the strut assembly on the vehicle
  24.  

Removal & Installation



  1. Raise and safely support the vehicle.
  2.  
  3. Remove the front wheel.
  4.  
  5. Remove the bolt securing the brake hose routing bracket to the strut assembly.
  6.  
  7. While holding the stabilizer bar link stud stationary, remove the nut securing the link to the strut assembly.
  8.  
  9. While holding the bolt heads stationary, remove the nuts from the bolts that attach the strut to the knuckle.

  10.  
  11. Remove the two bolts attaching the strut assembly to the knuckle using a pin punch.
    NOTE
    The bolts are serrated and cannot be turned.

  12.  
  13. Remove the three nuts attaching the strut upper mount to the strut tower.

  14.  
  15. Remove the strut assembly from the vehicle.
  16.  

To install:

  1. Install the strut assembly into the strut tower. Tighten the three mounting nuts to 35 ft. lbs. (48 Nm).
  2.  
  3. Position the lower end of the strut assembly in line with the upper end of the knuckle. Align the holes and install the two attaching bolts. While holding the bolt heads stationary, tighten the nuts to 62 ft. lbs. (84 Nm).
  4.  
  5. Attach the stabilizer links to the strut and tighten the nuts to 43 ft. lbs. (58 Nm).
  6.  
  7. Secure the brake hose routing bracket to the strut and tighten the screws to 10 ft. lbs. (13 Nm).
  8.  
  9. Install the front wheels.
  10.  
  11. Lower the vehicle.
  12.  
  13. Check and adjust the alignment as necessary.
