Wear safety gloves and goggles.

2. Lift the Vehicle

Using a hydraulic jack, lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands for safety.

3. Inspect Suspension Components

Inspect struts and shock absorbers for leaks or physical damage.
- Tools Required: Torque wrench, socket set.
- Sub-steps:
  - Remove the wheel to access the suspension components.
  - Check the strut assembly for any signs of oil leakage.
  - Ensure that the strut mounts are not cracked or damaged.

4. Replace Worn Components

If any components are found to be damaged, proceed with replacement.
- Tools Required: Socket set, torque wrench, impact wrench (if necessary).
- Sub-steps:
  - Remove the damaged component (e.g., strut, control arm).
