Solution

1. Preparation

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

2. Tire Inspection and Replacement

Sub-steps:
1. Use a tire pressure gauge to check all tires; inflate to manufacturer's recommended PSI if needed.
2. Inspect each tire for bulges, cuts, or uneven wear patterns. Replace any damaged tires.
Tools Required: Tire pressure gauge, floor jack, jack stands.

3. Suspension Component Inspection and Replacement

Sub-steps:
1. Lift the vehicle with a floor jack and secure it on jack stands.
2. Visually inspect the struts and shocks for leaks or damage.
3. If worn, remove the old struts/shocks by unbolting from the top and bottom mounts using a socket set.
4. Install new struts/shocks, ensuring proper torque specifications (typically 25-30 ft-lbs for top mounts, refer to service manual for specifics).
Tools Required: Socket set, torque wrench, impact wrench (optional).

4. Alignment Adjustment

Sub-steps:
1. After replacing suspension components, lower the vehicle back to the ground.
2. Take the car to a professional alignment shop to ensure wheels are aligned correctly.
Tools Required: Alignment rack (professional service).
