Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack and jack stands, strut spring compressor, wheel chocks.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Lift the Vehicle

Loosen the lug nuts slightly on the front wheels.
Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels.

3. Remove the Strut Assembly

Tools Required: Ratchet and socket set.
Disconnect the sway bar link from the strut.
Detach the brake line bracket from the strut assembly.
Remove the top strut mount bolts located under the hood.
Remove the lower strut bolts connecting the strut to the knuckle.
Carefully extract the strut assembly from the vehicle.

4. Replace or Repair Struts

Tools Required: Strut spring compressor.
If replacing, use the strut spring compressor to safely compress the coil spring on the old strut.
Remove the strut top nut and separate the spring from the strut.
Install the coil spring onto the new strut and secure with the top nut, following the manufacturer’s torque specifications.
If only repairing, ensure all seals and fluid are replaced in the strut assembly.

5. Reinstall the Strut Assembly

Insert the strut assembly back into the vehicle.
Reattach the lower strut bolts and torque to manufacturer specifications.
Secure the top strut mount bolts and torque accordingly.
Reattach the sway bar link and brake line bracket.

6. Reassemble the Vehicle

Place the front wheels back onto the vehicle and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts to the manufacturer’s specifications.
