Solution

1. Tire Inspection and Inflation

Sub-steps:
- Use a tire pressure gauge to check each tire's pressure.
- Inflate tires to the recommended pressure found on the driver's door jamb sticker.
- Inspect tires for any visible damage; replace if necessary.

2. Wheel Balancing

Sub-steps:
- Remove the wheel and tire assembly from the vehicle using a socket set.
- Take the tire to a tire shop for rebalancing if it is found to be unbalanced.
- Reinstall the wheel and torque lug nuts to the manufacturer's specifications (typically 100-120 ft-lbs).

3. Wheel Alignment

Sub-steps:
- If misalignment is suspected, perform a four-wheel alignment using an alignment machine.
- Adjust camber, caster, and toe settings according to manufacturer specifications.

4. Suspension Component Inspection and Replacement

Sub-steps:
- Visually inspect struts, shocks, and bushings for signs of wear or damage.
- Replace any damaged components with OEM parts.
- Refer to manufacturer specifications for torque values when reinstalling suspension components.
