Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a floor jack to lift the vehicle at the manufacturer's designated lift points.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Damaged Components

Struts/Shocks:
- Remove the wheel for access.
- Unbolt the strut assembly from the top mount and lower control arm.
- Inspect for oil leaks and replace if damaged.
- Torque new strut bolts to the manufacturer's specifications (usually around 50-60 ft-lbs).
Control Arms/Bushings:
- Locate control arm connections; remove bolts using a socket set.
- Inspect bushings for cracks; replace if worn.
- Reinstall the control arm and torque to specifications.
Sway Bar Links:
- Unbolt the sway bar link from the sway bar and lower control arm.
- Replace if any play is detected.
- Reinstall and torque to specification.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and torque lug nuts to the recommended specifications (usually around 80-100 ft-lbs).
Remove jack stands and lower the vehicle.

5. Final Inspection

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