What must be recorded on the MVI-2 form if a load-carrying ball joint is rejected?

The requirement to record the measured movement and its direction on the MVI-2 form when a load-carrying ball joint is rejected is crucial for several reasons. Documentation of the measured movement provides specific details regarding the extent of wear or damage in the suspension components, which is vital for understanding the severity of the issue. This information aids in ensuring that subsequent inspections or repairs are based on precise observations rather than subjective judgments. Furthermore, noting the direction of the movement helps in diagnosing the problem, as it indicates how the joint is functioning under load, pointing to potential misalignments or defects.

Recording only the reason for rejection would not provide the technical detail needed for a thorough understanding of the component's condition. Similarly, the inspection station's address and estimated cost of repairs, while important for other reasons, do not relate directly to the specifics of the ball joint’s condition and the reasoning behind its rejection during the inspection process. Thus, the requirement for detailed documentation on measured movement and its direction ensures a comprehensive understanding of the vehicle's condition for both repair professionals and vehicle owners.
