Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Lift the Vehicle

Using a jack, lift the vehicle and secure it with jack stands.
Remove the front or rear wheels (depending on which strut is being serviced) using a socket set.

3. Remove the Strut Assembly

Disconnect the stabilizer link from the strut using a wrench.
Remove the bolts securing the strut to the steering knuckle or lower control arm.
Unbolt the strut from the upper mount in the engine bay or trunk.
Carefully remove the strut assembly from the vehicle.

4. Inspect and Replace

Inspect the removed strut for leakage and overall condition.
If leaking, replace with new struts according to manufacturer specifications.
Transfer any necessary components (e.g., spring seats, bump stops) from the old strut to the new one.

5. Reassemble

Install the new strut into the vehicle, securing it to the upper mount first.
Reattach the strut to the steering knuckle or lower control arm using the original bolts.
Reconnect the stabilizer link.

6. Reinstall Wheels and Lower Vehicle

Reattach the wheels and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten lug nuts to the specified torque.
