Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery to ensure safety.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of all tires.
Inflate tires to the recommended pressure levels as found in the owner’s manual.

3. Tire Inspection

Remove the wheels using a socket set.
Inspect tires for bulges, cuts, or uneven wear. Replace any damaged tires if necessary.

4. Wheel Balancing

Mount the wheels on a dynamic balancing machine.
Follow the machine's instructions to balance each wheel, adding weights as required.
Reinstall the balanced wheels on the vehicle, ensuring proper torque specifications (usually 80-100 ft-lbs).

5. Suspension Component Inspection

Visually inspect all suspension components for signs of wear or damage.
Replace any worn components, such as bushings or control arms, as necessary.

6. Wheel Alignment

Use a four-wheel alignment machine to check and adjust wheel alignment.
Adjust camber, caster, and toe settings to manufacturer specifications.
