Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Tire Pressure and Condition Check

Sub-steps:
- Use a tire pressure gauge to check each tire's pressure.
- Inflate or deflate tires to the manufacturer-recommended pressure (found in the owner’s manual or on the driver’s door jamb).
- Visually inspect each tire for signs of damage or uneven wear.

3. Wheel Balancing

Sub-steps:
- Remove the wheel from the vehicle using a lug wrench.
- Take the wheel to a tire shop for balancing.
- Reinstall the wheel once balanced, ensuring lug nuts are torqued to the manufacturer’s specifications (typically 80-100 ft-lbs).

4. Wheel Alignment

Sub-steps:
- Take the vehicle to an alignment shop.
- Have a professional check and adjust the wheel alignment to the manufacturer’s specifications.
- Confirm all settings fall within acceptable limits.

5. Suspension Inspection

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Inspect all suspension components for wear, cracks, or damage.
- Replace any worn or damaged components (e.g., shocks, struts, bushings) as needed.
