Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, OBD-II scanner, socket set, torque wrench.
Safety Warning: Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Tire Inspection and Replacement

Check Tire Pressure:
- Use a tire pressure gauge to verify that all tires are inflated to manufacturer's specifications.
- Adjust tire pressures as necessary.
Inspect Tires:
- Check for uneven wear patterns, bulges, or cracks.
- Replace any damaged tires with new ones of the same size and specifications.

3. Suspension Component Inspection

Visual Inspection:
- Lift the vehicle using a jack and secure it with jack stands.
- Inspect the struts and shocks for leaks or physical damage.
Replace Shocks/Struts if Necessary:
- Remove the wheels for easier access.
- Disconnect the top and bottom bolts securing the shocks/struts.
- Replace with new parts, ensuring they are torqued to manufacturer specifications.

4. Alignment Adjustment

Perform Wheel Alignment:
- After replacing suspension components, take the vehicle to a professional alignment shop.
- Ensure that all alignment angles are within manufacturer specifications.
