Abstract
A system measures multiple operational angles of a driveline assembly and compares the signals to each other to determine whether the angles and the respective driveline components are properly balanced. Different types of sensor assemblies can be used to measure the operational angles including various types of contact and non-contact sensors. In one example, the operational angle between one axle differential case and a corresponding universal joint can be compared to the operational angle between another axle differential case and corresponding universal joint mounted at an opposite end of the driveline. If the angles are equal or very close to one another than the angles are properly balanced. If the ratio between the two angles exceeds a predetermined limit, the driveline components are not properly balanced and the components can be repositioned to avoid premature wear.
