Solution

1. Preparation

Gather tools: tire pressure gauge, jack, jack stands, lug wrench, wheel balancer, alignment tool.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate the tires to meet the recommended pressure listed on the driver’s side door jamb.

3. Wheel Balancing

Remove the wheel using a lug wrench.
Mount the wheel on a wheel balancer and check for any imbalance.
If imbalanced, attach wheel weights to the specified locations on the rim to balance the wheel.
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

4. Wheel Alignment

Use an alignment tool to check the alignment settings.
If out of specification, adjust the camber, caster, and toe settings as needed.
Ensure to follow the manufacturer’s specifications for adjustments.

5. Suspension Inspection

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