Solution

1. Tire Inspection and Maintenance

Check Tire Condition: Inspect all tires for uneven wear, bulges, or flat spots.
Inflate Tires: Ensure all tires are inflated to the manufacturer’s recommended pressure.
Replace Tires: If any tires are worn or damaged, replace them with OEM or high-quality tires.

2. Wheel Balancing

Remove Wheels: Use a socket set to remove the wheel lug nuts and take off the wheels.
Balance Wheels: Take the wheels to a tire shop for professional balancing.
Reinstall Wheels: Mount the balanced wheels back onto the vehicle and torque the lug nuts to the manufacturer's specifications (typically 100-110 ft-lbs).

3. Suspension Inspection

Visual Inspection: Check all suspension components for signs of wear or damage.
Replace Worn Parts: If any parts (like bushings or shock absorbers) are worn out, replace them using appropriate tools (e.g., ball joint separator, torque wrench).
Reassemble and Torque: Ensure all components are reassembled to the manufacturer's torque specifications.

4. Driveshaft and CV Joint Inspection

Inspect Driveshaft: Check the driveshaft for any signs of dents or damage.
Check CV Joints: Inspect the CV joint boots for tears and ensure there is no excessive play in the joints.
Replace if Necessary: If any issues are found, replace the affected components.

Tools Required:

Socket set
Torque wrench
