Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which strut is leaking.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Store the lug nuts in a safe place for reinstallation.

4. Disconnect the Strut

Remove the lower strut bolt using a socket set. You may need a breaker bar if the bolt is tight.
Remove the upper strut mounting nuts using a socket and ratchet. There may be a need for a torque wrench for proper reinstallation later.
Carefully extract the strut from the vehicle.

5. Install New Strut

Align the new strut into position and secure it with the upper strut mounting nuts.
Tighten the upper nuts to the manufacturer’s specified torque (consult service manual for exact torque values).
Reinstall the lower strut bolt and tighten it to the specified torque.

6. Reassemble Components

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and then torque the lug nuts to the manufacturer’s specifications.

7. Final Inspection

Check the alignment of the strut and ensure all components are secure.
Test the strut function by pressing down on the vehicle to ensure proper damping.
