Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the front or rear wheel (depending on which strut is leaking) using a lug wrench.

3. Remove the Strut

Tools Required: Socket set, torque wrench.
Remove the lower strut bolts using the socket set.
Locate the upper strut mounting bolts inside the engine bay (for front struts) or in the trunk area (for rear struts) and remove them.
Carefully detach the strut from the vehicle, ensuring to support it as you remove the last bolts.

4. Install New Strut

Position the new strut in place and align it with the mounting holes.
Secure the upper strut mount first, tightening to the manufacturer’s specified torque setting.
Attach the lower strut bolts and tighten them to the specified torque.
Ensure that all components are properly aligned and seated.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and fully tighten the lug nuts in a star pattern.
Test drive the vehicle to ensure proper handling and check for any further leaks.
