Solution

1. Preparation

Gather necessary tools and equipment.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Lift Vehicle

Use a jack to lift the vehicle at the manufacturer-recommended lift points.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to gain access to the strut assembly.

4. Remove Strut Assembly

Remove any necessary components obstructing access to the strut, such as brake lines or sway bar links (note the original positioning).
Unbolt the strut from the knuckle using a socket and ratchet.
Release the upper strut mounting bolts located under the hood or on the top of the strut tower.
Carefully remove the strut assembly from the vehicle.

5. Inspect and Replace

Inspect the removed strut for any signs of leakage or physical damage; if worn, replace with new struts.
If replacing, ensure to follow the manufacturer's specifications for torque values when installing new struts.

6. Reassemble

Reinstall the strut assembly in reverse order of removal.
Reattach the wheel and lug nuts, ensuring they are torqued to the manufacturer’s specifications.

7. Lower Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.

8. Wheel Alignment

It is recommended to perform a wheel alignment after strut replacement to ensure proper handling.
