Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lift it using a jack and jack stands.
Disconnect the negative battery terminal to avoid electrical issues.

2. Remove Strut Assembly

Tools Required: Socket set, torque wrench, pry bar.
Remove the wheel to access the strut assembly.
Loosen and remove the bolts securing the strut to the steering knuckle and the upper strut mount.
Carefully detach the strut from the vehicle, noting the orientation of the components.

3. Inspect and Replace

Examine the strut for signs of damage or excessive wear. If oil is leaking from the strut seals, replacement is necessary.
Replace the strut with a new or remanufactured unit.
Parts Required: New strut assembly, strut mount kit (if needed).
Reinstall the strut by reversing the removal steps, ensuring all bolts are tightened to the manufacturer's specified torque settings.
