Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Worn Components

Suspension Inspection:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the front wheels to gain access to suspension components.
Check Struts and Shocks:
- Inspect for oil leaks and physical damage.
- If found faulty, remove the strut assembly using a socket set (typically 14mm-19mm bolts).
- Replace with new struts or shocks, ensuring they match OEM specifications. Torque bolts to manufacturer specifications (usually around 50-70 ft-lbs).
Sway Bar Link Replacement:
- Inspect sway bar links for wear or disconnection.
- Remove and replace worn sway bar links. Use a torque wrench to tighten to manufacturer specifications (usually around 30 ft-lbs).

3. Reassemble and Lower the Vehicle

Reinstall the wheels and securely tighten the lug nuts.
Remove jack stands and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
