Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, strut spring compressor, screwdriver, pry bar
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid electrical issues.

2. Lift the Vehicle

Use a jack to lift the front or rear (depending on which strut is leaking) of the vehicle.
Securely place jack stands under the vehicle for safety.

3. Remove the Wheel

Use the socket set to remove the lug nuts.
Take off the wheel to gain access to the strut assembly.

4. Remove the Strut

Disconnect the brake line and any sensors attached to the strut.
Remove the bolts securing the strut to the steering knuckle using a socket.
Remove the upper strut mount bolts located in the engine bay or under the rear seat.
Carefully remove the strut from the vehicle.

5. Install New Strut

Parts Required: New strut assembly (ensure it matches OEM specifications), strut mounts (if needed), and any necessary hardware.
If reusing the old strut mount, ensure it is in good condition; otherwise, replace it.
Compress the spring using a strut spring compressor and install it onto the new strut if applicable.
Position the new strut in place and secure it with the upper and lower bolts.
Torque the bolts to the manufacturer's specifications (typically around 50-70 ft-lbs for the lower bolts and 30-40 ft-lbs for the upper bolts).

6. Reassemble Vehicle

Reattach the brake lines and sensors to the strut.
Reinstall the wheel and torque the lug nuts to specs (usually around 80-100 ft-lbs).
Lower the vehicle from the jack stands.

7. Final Checks

Reconnect the battery.
Ensure everything is secure and there are no leaks.
