Solution

1. Tire Inspection

Sub-steps:
- Use a tire pressure gauge to check each tire's pressure; inflate to the manufacturer's specifications if necessary.
- Inspect each tire for visible damage, such as cracks or bulges. Replace any damaged tires.

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a lug wrench.
- Take the wheels to a tire shop for balancing. They will use a balancing machine to ensure weights are applied correctly.
- Reinstall the balanced wheels and torque the lug nuts to the manufacturer's specifications (typically around 76 ft-lbs).

3. Suspension and Alignment Adjustment

Sub-steps:
- Inspect and replace any worn suspension components (e.g., control arms, bushings).
- Adjust the wheel alignment using an alignment machine according to the manufacturer’s specifications.

4. Brake Inspection

Sub-steps:
- Remove the wheel and inspect the brake rotors for warping or uneven wear. Replace any warped rotors.
- Check the brake pads for wear and replace them if necessary.

5. Drivetrain Inspection

Sub-steps:
- Inspect CV joints for damage and replace if any play is detected.
- Check wheel bearings for wear; replace if they are loose or noisy.
