Solution

1. Preparation

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

2. Raise 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 to ensure stability.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel, exposing the strut assembly.

4. Detach the Strut Assembly

Remove the bolts securing the strut to the steering knuckle using a socket set.
Disconnect any brake lines or sensors attached to the strut if applicable.
Remove the top mount bolts located under the hood or within the passenger compartment to detach the strut from the chassis.

5. Replace the Strut

Position the new strut in place and secure it to the top mount with the bolts.
Reattach the strut to the steering knuckle, ensuring all bolts are tightened to the manufacturer’s specifications (consult the repair manual for torque values).
Reconnect any brake lines or sensors that were detached.

6. Reinstall the Wheel and Lower the Vehicle

Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the jack.
Tighten the lug nuts in a crisscross pattern to ensure even pressure.

7. Final Inspection

Inspect the strut installation for any visible issues.
Check the clearance of the strut and surrounding components.
