Solution

1. Tire Pressure Adjustment

Check tire pressure: Use a tire gauge to measure the pressure in each tire.
Adjust pressure: Inflate or deflate tires to the manufacturer's recommended pressure.

2. Tire Inspection and Replacement

Visual inspection: Check for bulges, cracks, or uneven wear.
Replace damaged tires: If any tires are found defective, replace them with manufacturer-approved tires.

3. Wheel Balancing

Remove wheels: Use a socket set to remove the wheel nuts and take off the wheels.
Balance wheels: Mount the wheels on a wheel balancer and add weights as needed to achieve balance.
Reinstall wheels: Reattach the wheels using a torque wrench to ensure proper torque (typically 100-120 ft-lbs).

4. Wheel Alignment

Alignment check: Place the vehicle on an alignment rack and check alignment angles.
Adjust alignment: Make necessary adjustments to meet manufacturer specifications.

5. Suspension Inspection

Visual inspection: Examine suspension components for cracks or excessive wear.
Replace worn components: If any parts are found defective, replace them with OEM or high-quality aftermarket parts.
