Solution

1. Preparation

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

2. Inspect Suspension Components

Sub-steps:
- Remove the front wheels using a socket set.
- Check control arm bushings for cracks or excessive wear.
- Inspect struts and shocks for leaks or damage.
- Examine sway bar links for play and wear.

3. Replace Worn or Damaged Parts

Sub-steps:
- If any components are found to be worn, replace them with OEM or quality aftermarket parts.
- For control arms, remove the bolts using a torque wrench and replace with new components, tightening to manufacturer specifications (usually around 50-70 Nm).
- For struts, remove the retaining bolts and install new struts, ensuring proper alignment before tightening.

4. Reassemble and Lower Vehicle

Sub-steps:
- Reinstall wheels and torque lug nuts to specification (usually around 120 Nm).
- Lower the vehicle and remove jack stands.

5. Final Inspection

Inspect all replaced components for proper installation.
Ensure no tools are left under the vehicle.
