Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and turn off the ignition.
Wear safety gloves and goggles.

2. Tire Inspection and Maintenance

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the manufacturer's recommended levels.
Visual Inspection: Examine each tire for any visible cracks, bulges, or foreign objects embedded in the tread.
Tread Depth Check: Use a tread depth gauge to measure the tread. Replace tires if tread is below 2/32 inches.

3. Wheel Balancing

Remove Wheels: Loosen lug nuts and remove the wheels using a socket set.
Balance Wheels: Take the wheels to a tire shop for professional balancing or use a wheel balancer if available.
Reinstall Wheels: Place wheels back on the vehicle and hand-tighten lug nuts.

4. Wheel Alignment

Alignment Check: Use an alignment tool or visit a professional alignment service.
Adjust Alignment: Follow the manufacturer's specifications to adjust the angles of the wheels if misaligned.

5. Suspension Inspection

Visual Inspection: Look for any visible signs of wear or damage to suspension components (struts, shocks, control arms).
Test Components: Manually test for play in the ball joints and bushings by applying force and checking for excessive movement.
Replace Worn Parts: Replace any damaged or worn suspension components as needed.
