Solution

1. Preparation

Gather tools and necessary parts.
Park the vehicle on a level surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect Suspension Components

Strut Mounts:
- Remove the strut assembly by unbolting it from the knuckle and the top mount.
- Inspect the strut mounts for cracks or signs of deterioration.
- Replace if necessary with OEM parts.
Sway Bar Links and Bushings:
- Inspect for any wear or damage.
- Remove any damaged links by unbolting them from the sway bar and control arm.
- Replace with new sway bar links and bushings.

4. Reassemble Front Suspension

Reinstall the strut assembly, ensuring all bolts are torqued to the manufacturer's specifications (typically around 60-80 Nm for strut bolts).
Reattach the front wheels and lower the vehicle back to the ground.

5. Final Inspection

Double-check all components to ensure tightness and proper installation.
Re-check the torque specifications for all fasteners.
