Solution

1. Tire Inspection and Maintenance

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the manufacturer's recommended settings.
Inspect for Damage: Look for any bulges, cuts, or punctures on the tire surface.
Rotate Tires: If uneven wear is found, rotate the tires to promote even wear.

2. Wheel Balancing

Remove Wheels: Use a jack to lift the vehicle and remove the wheel using a socket set.
Balance Wheels: Mount the wheel on a wheel balancer and adjust weights as necessary to achieve a balanced wheel.
Reinstall Wheels: Torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

3. Suspension Inspection

Visual Inspection: Check all suspension components (control arms, bushings, ball joints) for signs of wear.
Replace Worn Components: If any components are found to be worn or damaged, replace them with OEM or quality aftermarket parts.

4. Driveshaft and CV Joint Inspection

Inspect Driveshaft: Examine the driveshaft for any signs of damage or excessive play by shaking it gently.
Check CV Joints: Look for grease leakage or cracks in the boot. Replace any damaged CV joints or shafts.

5. Alignment Adjustment

Check Alignment: Use an alignment machine to assess all four wheels' alignment settings.
Adjust as Necessary: Adjust the toe, camber, and caster settings to match the manufacturer's specifications.
