Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, socket set.
Ensure the vehicle is parked on a level surface, and engage the parking brake.

2. Tire Inspection and Adjustment

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Use a tire pressure gauge to check the pressure of each tire; inflate or deflate to recommended levels.
3. Inspect each tire for uneven wear patterns or bulges; replace damaged tires if necessary.

3. Suspension Component Replacement

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels to access the suspension components.
3. Inspect and remove any worn or damaged shock absorbers and struts.
  - Use a socket set to remove the bolts securing the components.
  - Replace with new shocks or struts as needed.
4. Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications.

4. Alignment Check

Sub-steps:
1. After replacing suspension components, take the vehicle to a certified alignment shop.
2. Ensure the vehicle is aligned according to the manufacturer’s specifications to prevent uneven tire wear and maintain handling stability.
