Solution

1. Preparation

Gather tools and materials: jack, jack stands, tire pressure gauge, torque wrench, and tire balancing equipment.
Ensure the vehicle is on a flat, stable surface.
Disconnect the battery if working on any electronic components.

2. Tire Inspection and Adjustment

Check the tire pressure using a gauge and inflate to the manufacturer's specifications.
Visually inspect each tire for signs of damage or uneven wear.
Replace any damaged tires with new ones if necessary.

3. Wheel Alignment

Use an alignment tool to measure the angles of the tires.
Adjust the camber, caster, and toe settings to match the manufacturer’s specifications.
Tighten all adjustment bolts to the specified torque values.

4. Wheel Balancing

Remove the wheels from the vehicle using a jack and jack stands.
Mount the tires on a balancing machine to check for imbalance.
Add weights as necessary to balance each wheel.

5. Suspension and Drivetrain Inspection

Inspect all suspension components, including control arms, bushings, and shocks for wear.
Check the driveshaft for any play or damage, and ensure CV joints are in good condition.
