Solution

1. Preparation

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

2. Inspect and Tighten Components

Tools Required: Socket set, torque wrench
Inspect all bolts and fasteners on the suspension components and the undercarriage.
Tighten any loose bolts to the manufacturer's specified torque values (refer to the service manual).

3. Replace Worn Parts

Tools Required: Socket set, jack and jack stands, torque wrench
If any components (bushings, struts, shock absorbers) are found to be damaged:
- Lift the vehicle with a jack and secure with jack stands.
- Remove the wheel for easier access to the suspension.
- Unbolt and replace the worn component with a new part.
- Reinstall the wheel and lower the vehicle.

4. Inspect and Adjust Sway Bar Links

Tools Required: Wrench set
Check sway bar links for any signs of wear.
If damaged, remove the old sway bar link by unbolting it from the sway bar and the control arm.
Install the new sway bar link and make sure it is properly tightened.
