A vehicle wheel speed sensor of the type using permanent magnets to generate a magnetic field having a magnetic path which is conducted through a plurality of teeth (32) on a rotor (30) into a plurality of teeth (37) on a stator (36) with relative motion therebetween where the frequency of the change in the magnetic reluctance varies at a frequency proportional to the wheel speed. The stator (36) is mounted to the end of the axle spindle (10) by way of a securing bolt (50,52) so that the stator (36) can be easily removed for service without disturbing the axle bearings (14). As a part of the stator assembly, a locating plate (46) is provided which allows the operating gap between the rotor (30) and the stator (36) to be easily established upon assembly of the hub cap (22) to the wheel hub (18) by allowing the rotor (30) to contact the locating plate (46) when the hub cap securing bolts (24) have been loosened and the axle (10) is supported. <IMAGE>
