Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Raise the vehicle with a jack and support it on jack stands.

2. Inspect and Replace Suspension Components

Inspect Struts/Shocks:
- Remove the wheel to access the strut.
- Check for oil leaks around the strut body.
- If leaking, remove the strut assembly using a socket set.
- Replace with new struts if necessary.
Check Bushings:
- Use a pry bar to check for play in control arm bushings.
- If excessive movement is noted, remove the control arm using a socket set.
- Replace with new bushings and reassemble.
Examine Sway Bar Links:
- Inspect sway bar links for wear or separation.
- Remove the sway bar link using a socket set if damaged.
- Install new sway bar links and ensure tight connections.

3. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle to the ground.
Torque all fasteners to the manufacturer's specifications.
