John Deere RE558874 Wheel Speed Sensor

The RE558874 is a genuine John Deere wheel speed sensor designed to measure rotational velocity of the wheel hub and transmit signal data to the vehicle electronic control unit for traction control, anti-lock braking, and transmission management. The sensor features a threaded body with an overall length of 85 mm and a two-wire connector interface. It operates on inductive or Hall-effect principle compatible with 12V and 24V electrical systems standard in John Deere agricultural tractors. The component is sealed to IP67 standards for resistance against mud, water, and high-pressure washing typical in field operations. This part supersedes earlier revisions RE295929 and RE204888 and serves as a direct fit replacement without harness modification. Installation requires standard hand tools and torque specification per John Deere service manual for the specific tractor model.
