Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, strut spring compressor, impact wrench (optional).
Park the vehicle on a flat surface and engage the parking brake.
Loosen the lug nuts on the front wheels without removing them.

2. Lift the Vehicle

Sub-steps:
1. Use the jack to lift the front of the vehicle and secure it with jack stands.
2. Remove the lug nuts and take off the front wheels.

3. Remove Strut Assembly

Sub-steps:
1. Disconnect the sway bar link from the strut using a socket.
2. Remove the brake line bracket attached to the strut.
3. Unbolt the strut from the steering knuckle (usually two bolts).
4. Access the upper strut mounting bolts located under the hood and remove them.
5. Carefully pull the strut assembly out of the vehicle.

4. Replace or Repair Strut

Sub-steps:
1. If replacing, use a strut spring compressor to safely compress the coil spring.
2. Remove the top mount from the old strut and install it onto the new strut.
3. Reassemble the coil spring onto the new strut using the strut spring compressor.
4. If repairing, ensure seals are replaced, and reassemble the strut according to manufacturer specifications.

5. Reinstall Strut Assembly

Sub-steps:
1. Insert the strut assembly back into the vehicle, securing the upper mount first.
2. Tighten the upper mounting bolts to the manufacturer’s torque specifications.
3. Reattach the strut to the steering knuckle and tighten the bolts.
4. Reconnect the sway bar link and brake line bracket.

6. Reassemble Vehicle

Sub-steps:
1. Reinstall the front wheels and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and use the torque wrench to tighten lug nuts to specification.
