Solution

1. Preparation

Gather all tools and parts needed.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery for safety.

2. Inspect and Replace Worn Suspension Components

Raise the Vehicle:
- Use a jack to lift the front end of the vehicle.
- Secure with jack stands.
Remove Wheel:
- Use a socket set to remove the lug nuts and take off the front wheel.
Inspect the Suspension:
- Check the struts, control arms, sway bar links, and bushings.
- If any component is damaged or excessively worn, proceed to replace it.
Replace Worn Components:
- For sway bar links:
  - Remove the old link by unbolting it from both the sway bar and the control arm.
  - Install the new sway bar link and torque to manufacturer's specifications (typically between 30-40 ft-lbs).
- For struts:
  - Unbolt the strut assembly from the knuckle and the top mount.
  - Replace the strut with a new one and ensure all bolts are tightened to the specified torque.

3. Reassemble and Lower Vehicle

Reinstall Wheel:
- Place the wheel back on and hand-tighten the lug nuts.
Lower the Vehicle:
- Carefully remove the jack stands and lower the vehicle using the jack.
Torque Lug Nuts:
- Tighten lug nuts in a star pattern to the manufacturer's specification (typically 100-110 ft-lbs).
