Solution

1. Tire Inspection and Service

Inspect and Inflate Tires
- Check the tire pressure using a tire gauge.
- Inflate tires to the recommended PSI as indicated on the driver’s door jamb sticker.
Visual Inspection
- Examine each tire for visible damage, such as cuts, bulges, or uneven wear.
- If damage is found, replace the affected tire(s).

2. Wheel Balancing

Remove Wheels
- Use a lug wrench to loosen and remove the lug nuts.
- Lift the vehicle using a jack and secure it with jack stands before removing the wheels.
Balance Wheels
- Place each wheel on a tire balancing machine.
- Follow the machine's instructions to add weights as needed to achieve proper balance.
Reinstall Wheels
- Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (usually around 100-150 ft-lbs, check specific values for your model).

3. Suspension Inspection and Repair

Inspect Suspension Components
- Check the condition of shocks, struts, and control arms for signs of wear or damage.
- Pay attention to bushings and joints for excessive play.
Replace Worn Components
- If any parts are found to be worn or damaged, replace them with OEM or high-quality aftermarket parts.
- Ensure proper alignment of the suspension after any replacements.
