Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, strut spring compressor, and safety glasses.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Raise the Vehicle

Use the 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

Remove the lug nuts using a socket wrench.
Take off the wheel to access the strut assembly.

4. Remove the Strut Assembly

Top Mount Bolts: Locate and remove the top mount bolts securing the strut to the vehicle body using a socket wrench.
Lower Mount Bolts: Remove the lower mount bolts connecting the strut to the steering knuckle.
Carefully lower the strut assembly from the vehicle.

5. Replace the Strut

If replacing the strut, compress the coil spring using a strut spring compressor.
Remove the old strut from the spring and install the new strut into the spring.
Reassemble the strut assembly by reversing the removal process, ensuring all nuts and bolts are torqued to manufacturer specifications.

6. Reinstall Wheel and Lower Vehicle

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

7. Final Checks

Reconnect the negative battery terminal.
Inspect for leaks around the new strut and ensure all components are secured.
