Solution

1. Tire Inspection and Adjustment

Sub-steps:
- Use a tire pressure gauge to measure each tire's pressure.
- Inflate or deflate tires to the recommended PSI listed on the driver’s side door jamb.
- Visually inspect each tire for damage or uneven wear.

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket wrench.
- Mount each wheel on a tire balancing machine.
- Add weights as required to balance the wheel properly.
- Reinstall the balanced wheels on the vehicle, ensuring proper torque (typically 100-150 ft-lbs).

3. Suspension Inspection

Sub-steps:
- Lift the vehicle using a hydraulic jack and secure it with jack stands.
- Inspect tie rods, control arms, and bushings for any signs of wear or damage.
- Replace any worn components with OEM or high-quality aftermarket parts.
- Reassemble the suspension components and ensure proper torque specifications are met.

4. Wheel Alignment

Sub-steps:
- Drive the vehicle onto an alignment rack.
- Follow the manufacturer's specifications to adjust camber, caster, and toe angles.
- Confirm that all adjustments are within the specified ranges.
