Solution

1. Tire Inspection and Repair

Inspect Tire Condition: Check for bulges, cracks, or uneven wear.
Adjust Tire Pressure: Inflate tires to the manufacturer-recommended PSI.
Replace Tires if Necessary: If tires are worn or damaged, replace with OEM or high-quality tires.

2. Suspension Component Check

Visual Inspection: Look for signs of wear (cracks, breaks) on control arms, bushings, and struts.
Replace Worn Components: If any components are damaged or worn, replace them using OEM parts.
Reassemble: Ensure all components are properly torqued to manufacturer specifications.

3. Wheel Alignment and Balancing

Perform Wheel Alignment: Use a professional alignment machine to align the wheels.
Balance Wheels: Ensure that all wheels are balanced correctly to prevent vibrations.
Test Drive: After alignment and balancing, take the vehicle for a test drive to confirm the issue is resolved.

4. Driveshaft and CV Joint Inspection

Inspect Driveshaft: Look for signs of wear or damage on the driveshaft.
Check CV Joints: Ensure that the CV joints are in good condition without any tearing in the rubber boots.
Replace if Necessary: If damaged, replace the driveshaft or CV joints.
