VEHICLE DESCRIPTION: TRAILERS EQUIPPED WITH HUBS PROVIDED BY WEBB WHEEL PRODUCTS. THESE TRUCK TRAILER DISC WHEEL HUBS HAVE DIRECT-MACHINED ANTI-LOCK BRAKING SYSTEMS (ABS), PART NUMBER 2023A. THE ABS TEETH ARE MACHINED INTO THE INNER FACE OF THE HUB BORE, AND THE TEETH ARE MACHINED OFF CENTER FROM THE CENTER OF THE HUB. THE SPEED SENSOR OF THE ABS SYSTEM READS THE TOOTH PATTERN AND SENDS ERRONEOUS SIGNALS TO THE ABS CONTROL UNIT.
