Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Wear safety goggles and gloves.

2. Remove the Wheel

Loosen the lug nuts with a socket wrench.
Lift the vehicle using a hydraulic jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove the Strut Assembly

Disconnect any brake lines or sensors attached to the strut, taking care to avoid damage.
Remove the bolts securing the strut to the steering knuckle.
Remove the upper strut mounting nuts in the engine bay, which may require access from under the hood.
Carefully extract the strut assembly from the vehicle.

4. Inspect the Strut

Visually examine the strut for any signs of oil leakage.
Check the strut bushings and mounts for cracks or deterioration.
If necessary, compare the strut with a new one to assess wear.

5. Replace or Repair

If the strut is damaged, replace it with a new unit, ensuring proper alignment of the mounting holes.
If only bushings or mounts are worn, replace them while keeping the original strut.
Torque all bolts to the manufacturer’s specifications.

6. Reassemble

Reinstall the strut assembly in reverse order, securing all bolts and connections firmly.
Reattach the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Torque Wheel Bolts

Lower the vehicle back to the ground.
Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
