Solution

1. Preparation

Gather tools such as a jack, jack stands, tire pressure gauge, and torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Maintenance

Sub-steps:
1. Check the tire pressure and inflate to the recommended PSI as indicated on the driver’s door jamb sticker.
2. Visually inspect each tire for uneven wear, cracks, or bulges.
3. Rotate tires if uneven wear is detected, ensuring a proper tire rotation pattern (front-to-back or crisscross).

3. Wheel Balancing

Sub-steps:
1. Remove the wheel covers or caps if applicable.
2. Take each wheel to a professional tire shop for balancing.
3. Reinstall the wheels and torque the lug nuts to manufacturer specifications (typically 100-150 ft-lbs depending on model).

4. Suspension Inspection and Repair

Sub-steps:
1. Lift the vehicle with a jack and secure it on jack stands.
2. Inspect shocks and struts for leaks or physical damage; replace as necessary.
3. Examine control arms and bushings for deterioration; replace worn components.

5. Alignment Adjustment

Sub-steps:
1. After replacing any suspension components, take the vehicle to a professional alignment shop.
2. Request a four-wheel alignment and ensure all angles are adjusted to manufacturer specifications.
