Utility Vs2r — 00V102003
Summary
VEHICLE DESCRIPTION: VAN-REFRIGERATED/DRY FREIGHT TRAILERS EQUIPPED WITH CONMET PREGREASED TRAILER HUBS AND A TIRE INFLATION SYSTEM. THE OUTBOARD BEARING ON THE PREGREASED TRAILER AXLE HUBS USED WITH THE TIRE INFLATION SYSTEMS MAY FAIL DUE TO THE INTRUSION OF CONTAMINANTS THROUGH THE TIRE INFLATION SYSTEM.
Consequence
AN OUTBOARD BEARING FAILURE CAN RESULT IN A SEPARATION OF THE HUB ASSEMBLY FROM THE SPINDLE.
Remedy
AUTHORIZED DEALERS ARE INSTRUCTED TO CONVERT GREASED HUBS TO OIL HUBS IF THE TIRE INFLATION SYSTEM IS TO REMAIN ON THE TRAILER. IF THE TIRE INFLATION SYSTEM IS REMOVED, THE HUB MUST BE INSPECTED FOR CONTAMINATION AND CORROSION. THE HUB AND BEARING ASSEMBLY MUST BE REPLACED IF THERE IS EVIDENCE OF CORROSION. IF THERE IS NO EVIDENCE OF CORROSION, LUBRICANT AND SEAL MANITENANCE CAN BE PERFORMED AND THE HUB REINSTALLED.
