Solution

1. Preparation

Gather tools such as a jack, jack stands, torque wrench, and socket set.
Ensure the vehicle is on a flat surface and the ignition is turned off.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to ensure stability.

3. Remove Components

If necessary, remove any components blocking access to the suspension parts (e.g., wheel or mud guard).
Use a socket set to remove bolts securing struts or sway bar links.

4. Inspect Components

Check bushings for cracks or excessive wear; replace if necessary.
Inspect struts for leaks or damage; replace if found faulty.
Examine sway bar links for play and replace if they are worn.

5. Reassemble

Reattach all components in the reverse order of removal.
Torque all bolts to the manufacturer specifications (refer to service manual for values).

6. Lower the Vehicle

Carefully lower the vehicle off the jack stands using the jack.
Ensure all tools are removed from under the vehicle.
