Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface, and engage the parking brake.
• Wear safety gloves and goggles.

2. Tire Inspection

• Remove the wheel covers if applicable.
• Inspect tires for uneven wear patterns, bulges, or sidewall damage.
• Measure tire pressure with a tire gauge and inflate to the manufacturer's recommended pressure if needed.

3. Wheel Balancing

• Remove the wheel from the vehicle using a jack and jack stands.
• Mount the wheel onto a wheel balancer.
• Adjust balance by adding or repositioning weights until the wheel is balanced.

4. Wheel Alignment

• Reinstall the wheel and lower the vehicle.
• Use an alignment machine to check camber, caster, and toe settings.
• Adjust the alignment settings to match the manufacturer’s specifications.

5. Suspension and Drivetrain Inspection

• Visually inspect suspension components for wear or damage.
• Check for any play in the wheel bearings by grabbing the tire at 3 and 9 o'clock positions and trying to rock it.
• Replace any damaged components as necessary.
