A device to monitor the mounting and bearing integrity of a wheel mounted on an axle where a multiplicity of studs are used each having retainers therefore. A follower of generally dielectric material and having an electrical conductor is biased against the side of the wheel. An electrical contact maintains contact with the follower periphery and is relatively movable between the dielectric periphery and the conductor located in the periphery. The first electrical contact is fixed to the vehicle wheel. Monitor means indicates the electrical connection of the electrical contact and the follower conductor as an indication of the movement of the wheel from its previously fixed position on an axle.
