Solution

1. Preparation

Gather tools and necessary parts.
Ensure the vehicle is parked on a flat surface and secure.
Disconnect the battery if working on electronic components.

2. Tire Inspection and Replacement

Inspect Tires:
- Remove the wheel covers if applicable.
- Check for bulges, cuts, or foreign objects embedded in the tire.
Replace Tires:
- If tires are worn or damaged, remove the wheels using a socket set.
- Install new tires, ensuring they are properly seated on the rims.
- Torque lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

3. Wheel Balancing

Balance Wheels:
- Mount the wheels on a tire balancing machine.
- Adjust weight placement as indicated by the machine to eliminate vibrations.
Reinstall Wheels:
- Mount balanced wheels back onto the vehicle.
- Torque lug nuts to specifications.

4. Suspension and Bearing Inspection

Inspect Suspension:
- Physically check shocks, struts, and control arms for wear.
- Replace any damaged or worn components.
Check Wheel Bearings:
- Raise the vehicle and check for play in the wheel bearings by shaking the wheel.
- If play is detected, replace the wheel bearings.
