Answer
Kerb Mass: Check the total weight of the vehicle including all necessary items to ensure proper alignment settings.
Tire Pressure: Verify that the tires are inflated to the manufacturer’s specifications to prevent alignment issues.
Suspension Components: Assess the condition of suspension parts for wear and play, as these can affect alignment.
Steering System: Ensure the steering components are functioning correctly, as they play a vital role in alignment.
