Solution

1. Tire Balancing

1.1 Lift the vehicle using a hydraulic jack and securely place it on jack stands.
1.2 Remove the wheels using a socket set.
1.3 Mount each wheel on a wheel balancer and check for imbalances.
1.4 Add weight as necessary to balance the wheels, following the balancer's instructions.
1.5 Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

2. Tire Replacement (if necessary)

2.1 Inspect tires for signs of excessive wear or damage.
2.2 If tires are worn unevenly, replace them with new tires of the same size and specifications.
2.3 Ensure the new tires are balanced and aligned properly.

3. Suspension Repair (if necessary)

3.1 Conduct a thorough visual inspection of suspension components for play or damage.
3.2 Replace any worn components such as control arms, tie rods, or bushings with OEM or high-quality aftermarket parts.
