Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety warning: Engage the parking brake and use wheel chocks.

2. Tire Balancing

Remove the wheel from the vehicle using a lug wrench.
Mount the tire on a balancing machine to check for imbalances.
Add weights to the rim as needed to achieve balance.
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (typically around 100-150 lb-ft).

3. Wheel Alignment

Place the vehicle on an alignment rack.
Follow the machine's instructions to measure the alignment angles (camber, caster, toe).
Adjust the tie rod ends and other components to align the wheels as per specifications.
Confirm alignment is within manufacturer’s tolerances.

4. Suspension Inspection and Repair (if required)

Raise the vehicle on jack stands and remove the wheels.
Inspect the suspension components for play or damage.
Replace any worn or damaged components (e.g., tie rods, control arms, or shocks) as necessary.
Reassemble all components and reinstall the wheels.
