Solution

1. Preparation

Tools Required: Socket set, jack, jack stands, torque wrench, pry bar, suspension strut tool (if needed).
Ensure the vehicle is parked on a level surface, engage the parking brake, and wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect Suspension Components

Shock Absorbers/Struts:
- Remove the wheel using a socket set.
- Check for oil leakage around the strut or shock absorber.
- If damaged, replace the strut/shock absorber.
Control Arms:
- Inspect the control arm bushings for cracks or separation.
- If worn, remove and replace the control arm.
Sway Bar Links:
- Use a pry bar to check for play in the sway bar links.
- Replace if excessive play is observed.

4. Reassemble and Torque

Reattach any components that were removed or replaced.
Use a torque wrench to tighten all bolts to the manufacturer's specifications (refer to the service manual for specific torque values).

5. Lower the Vehicle

Carefully lower the vehicle back to the ground and remove the jack stands.
