When measuring the height of a vehicle for spring and torsion bar inspection, what should be done?

Using a level surface as a starting point is essential when measuring the height of a vehicle for spring and torsion bar inspection. This ensures that measurements are accurate and not affected by any variations in the ground where the vehicle might be parked. A level surface provides a consistent baseline for height measurements, which is critical for determining whether the vehicle's suspension components are functioning correctly and if the ride height falls within the manufacturer's specifications.

This practice helps eliminate discrepancies caused by inclines or declines in the surface, which could lead to erroneous conclusions about the state of the vehicle’s suspension system. Accurate height measurements are crucial for identifying potential issues such as sagging springs or misaligned torsion bars, both of which can negatively impact vehicle handling and safety.
