The problem
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, AND MANUFACTURED BETWEEN APRIL 14 AND JUNE 7, 2000. 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.
Risk
THIS CONDITION CAN CAUSE THE ABS SYSTEM TO CYCLE RAPIDLY AND EXTEND STOPPING DISTANCES DURING AN ABS CONTROLLED BRAKE APPLICATION POSSIBLY RESULTING IN A VEHICLE CRASH.
What owners should do
WEBB WHEEL WILL NOTIFY THE CUSTOMERS TO INSPECT FOR DEFECTIVE HUBS AND WILL REPLACE THE HUBS FREE OF CHARGE.
