Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

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

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the strut assembly.

4. Disconnect the Strut

Remove the bolts securing the strut at the bottom using a socket set.
Remove the top mounting nuts from the strut tower. You may need to access the engine compartment for this.
Carefully pull the strut out from the assembly.

5. Inspect the Strut

Examine the strut for signs of damage or wear. If the strut is leaking, it must be replaced.

6. Install New Strut

Position the new strut in place and secure it at the top and bottom with the mounting bolts.
Torque the bolts to the manufacturer’s specifications (usually around 30-50 Nm for the lower mount and 20-25 Nm for the upper mount).

7. Reinstall the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then use the torque wrench to tighten the lug nuts to the manufacturer’s specifications (typically 120 Nm).

8. Final Checks

Ensure all tools are removed from the work area.
Double-check that all connections are secure.
