Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Inspection and Replacement

Inspect Tires:
- Remove the wheel covers or hubcaps if applicable.
- Visually inspect each tire for bulges, cracks, or uneven wear.
Replace Tires (if necessary):
- Use a tire removal tool to remove the tires that are damaged.
- Install new tires following the manufacturer’s recommendations for size and type.
- Torque lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

3. Wheel Balancing

Balance Wheels:
- Mount each wheel on a balancing machine.
- Adjust the weight distribution by adding or removing weights until balanced.
Reinstall the wheels on the vehicle.

4. Suspension Inspection and Repair

Inspect Suspension Components:
- Check control arms, bushings, and ball joints for signs of wear.
- Replace any damaged components using appropriate tools (e.g., socket set, wrenches).
Reassemble and torque all components to manufacturer specifications.

5. Wheel Alignment

Perform Wheel Alignment:
- Use a wheel alignment machine to measure and adjust the angles of the wheels.
- Adjust the camber, caster, and toe settings to meet manufacturer specifications.
