Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is on a flat surface.
Tools Required: Jack, jack stands, torque wrench, tire pressure gauge, wheel balancer (if available).
Safety Warnings: Ensure the vehicle is securely lifted and supported before working underneath.

2. Tire Inspection and Adjustment

Check the tire pressure using a tire pressure gauge.
Inflate tires to the recommended PSI as indicated on the door jamb or owner's manual.
Inspect each tire for signs of damage or uneven wear. Replace any damaged tires.

3. Wheel Balancing

Remove the wheel from the vehicle using the jack and jack stands.
Take the wheel to a wheel balancing machine.
Balance the wheel by adding weights as needed to achieve even distribution.
Reinstall the wheel and torque lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

4. Suspension Inspection

Visually inspect all suspension components for cracks, wear, or damage.
Replace any worn or damaged parts, such as bushings, control arms, or shocks.
Ensure all fasteners are tightened to the specified torque settings.

5. Wheel Alignment

After addressing tire and suspension issues, perform a wheel alignment.
Adjust front and rear alignment settings to manufacturer specifications.
Test drive the vehicle to check for improved handling.
