Solution

1. Tire Inspection and Maintenance

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to manufacturer specifications. Inflate as necessary.
Inspect Tires: Look for signs of uneven wear or damage. Replace tires if needed.

2. Wheel Alignment and Balancing

Alignment Check: Use an alignment machine to check for proper alignment. Adjust as required.
Balancing: If tires are unevenly worn or if vibrations persist, have the wheels balanced at a tire shop.

3. Suspension Component Inspection

Visual Inspection: Check control arms, bushings, and struts for wear or damage.
Replace Worn Components: If any components are damaged, replace them with OEM or quality aftermarket parts.

4. Driveshaft and CV Joints Inspection

Visual Inspection: Examine the driveshaft and CV joints for cracks or excessive play.
Replacement: If damaged, replace the driveshaft or CV joint as needed. Ensure proper torque settings are followed.

5. Error Code Analysis

Scan for Codes: Use an OBD-II scanner to check for any fault codes that might indicate engine or transmission issues.
Address Issues: If codes are present, refer to the manufacturer's service manual for detailed repair instructions.
