Solution

1. Tire Inspection and Maintenance

Check Tire Pressure: Use a tire pressure gauge to ensure tires are inflated according to the specifications found on the driver's door jamb.
Inspect Tread and Sidewalls: Look for cracks, bulges, or uneven wear; replace tires if damaged or excessively worn.

2. Wheel Balancing

Remove Wheels: Use a jack and jack stands to safely elevate the vehicle and remove the wheels using a socket set.
Balance Wheels: Take the wheels to a tire shop to have them balanced; they may need weights added or adjustments made.

3. Inspect and Replace Suspension Components

Visual Inspection: Check for signs of wear on suspension parts such as control arms, struts, and bushings.
Replacement: If any components are worn, replace them with OEM or high-quality aftermarket parts, following proper torque specifications for installation.

4. Alignment Adjustment

Set Up Alignment Equipment: Ensure the vehicle is on a level surface and properly positioned for alignment.
Adjust Alignment: Follow the manufacturer's specifications for camber, caster, and toe settings using alignment tools; adjust as necessary.
