Disassembly & Assembly




CAUTION
The coil springs are under a considerable amount of tension. Be very careful when removing or installing them; they can exert enough force to cause very serious injury.

  1. Remove the strut from the vehicle.
  2.  
  3. Disassemble the strut as follows:
    1. Step 1: Place the strut assembly into compressor tool, to compress the coil spring.
    2.  
    3. Step 2: Compress the spring slightly.
    4.  
    5. Step 3: Hold the strut shaft from turning using a No. 50 Torx® socket and remove the 24mm nut on the top end of the strut.
    6.  
    7. Step 4: Install Rod tool J 34013-38 to help guide the strut shaft from the upper mount assembly.
    8.  
    9. Step 5: Loosen the spring compressor tool until the coil spring and mount can be removed as an assembly. Remove the lower spring insulator, if equipped.

To install:

  1. Assemble the strut as follows:
    1. Step 1: Place the strut in compressor tool.
    2.  
    3. Step 2: Install the coil spring over the strut.
    4.  
    5. Step 3: Compress the coil spring while guiding strut shaft through the top of the strut assembly.
    6.  
    7. Step 4: Install the top strut nut. Torque the nut to 55 ft. lbs. (75 Nm).
    8.  
    9. Step 5: Remove the strut from the compressor.

  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Matchmark the strut-to-steering knuckle location.
  4.  
  5. If equipped with electronic ride control, detach the electrical connection.
  6.  
  7. Remove or disconnect the following:

    3 upper strut mount nuts and allow the control arms to hang free
     
    Anti-lock Brakes System (ABS) front wheel speed sensor
     
    Wheel speed sensor bracket from the strut
