Solution

1. Tire Inspection and Maintenance

Inspect Tires: Check for uneven wear, bulges, or foreign objects.
Check Pressure: Verify that all tires are inflated to the recommended PSI.
Rotate Tires: If wear is uneven, rotate the tires according to the manufacturer's recommended schedule.

2. Wheel Alignment and Balancing

Alignment Check: Use a wheel alignment machine to check and adjust the alignment to manufacturer specifications (typically within ±0.1°).
Balancing Tires: Have tires balanced using a dynamic balancing machine; adjust as necessary until vibration is minimized.

3. Suspension Component Check

Visual Inspection: Check control arms, bushings, and shock absorbers for signs of wear or damage.
Replace Worn Parts: If any components are found to be defective, replace them using OEM parts.

4. Drivetrain Examination

Inspect Driveshaft and CV Joints: Look for signs of wear or damage; replace if necessary.
Check Motor Mounts: Ensure motor mounts are intact and replace if they show signs of degradation.
