An improved wheel speed sensor is mounted at the end of a spindle and includes wiring which passes through a central passageway in the spindle. The sensor is of a type to be employed with a toothed ring or rotor mounted in the hub cap for relative rotation between the sensor and the rotor to generate a signal indicative of wheel speed. The improvement includes providing the sensor with a support structure which can be bolted to a keyed lock ring of the wheel mounting assembly and which encircles an extended portion of the spindle to provide the desired coaxial alignment of the sensor and rotor. A sealing member between the support structure and the extended portion of the spindle prevents wheel bearing lubricating fluid in the hub cap area from escaping through the passageway in the spindle.
