1. A method for monitoring bearings of a mover in an independent cart system, comprising the steps of:
generating a feedback signal from at least one sensor mounted on the mover, wherein the at least one sensor is mounted proximate a bearing on the mover and wherein the feedback signal corresponds to a force present at the bearing;
transmitting the feedback signal from the at least one sensor to a controller for the independent cart system;
comparing the feedback signal from the at least one sensor to a predetermined threshold; and
generating a message when the feedback signal from the at least one sensor exceeds the predetermined threshold.
