Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Inspect and Replace Suspension Components

Lift the Vehicle:
- Use a jack to raise the vehicle and secure it with jack stands.
- Remove the front or rear wheels as needed.
Examine Shock Absorbers/Struts:
- Check for any oil leakage or damage.
- If defective, unbolt the top and bottom mounting points using a socket set.
- Replace with new shock absorbers/struts, ensuring proper alignment.

3. Check CV Joints

Inspect CV Boots:
- Look for cracks or tears in the rubber boot.
- If damaged, remove the axle nut with a socket set, and detach the axle from the hub.
- Replace the CV joint or axle as necessary.

4. Replace Sway Bar Links

Remove Sway Bar Links:
- Locate the sway bar links and use a wrench to detach them from the sway bar and lower control arm.
- Install new sway bar links, tightening to manufacturer specifications (usually around 30-40 ft-lbs).

5. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle from the jack stands.
Reconnect the battery.
