Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface.
Use wheel chocks to prevent rolling.
Disconnect the battery (if necessary for safety).

2. Raise Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which struts are leaking.
Secure with jack stands.

3. Remove Wheel

Using a lug wrench, remove the wheel covering the affected strut.

4. Remove Strut Assembly

Tools Required: Socket set, torque wrench
Unscrew the bolts securing the strut to the knuckle and remove them.
Detach the upper strut mount bolts from the vehicle’s body.
Carefully remove the strut assembly from the vehicle, ensuring no other components are damaged.

5. Inspect and Replace

Inspect the strut for damage. If it is leaking, it will need replacement.
Parts Required: New strut assembly (OEM recommended for quality)
Install the new strut assembly in reverse order of removal.
- Secure the upper mount bolts to the vehicle’s body to the manufacturer’s torque specifications.
- Reattach the strut to the knuckle and tighten bolts to specification.

6. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern.

7. Final Checks

Reconnect the battery if it was disconnected.
Lower the vehicle completely and perform a bounce test to ensure proper strut performance.
