1999 Wabash Trailer

ON CERTAIN TRAILERS EQUIPPED WITH SEALCO SPRING BRAKE CONTROL VALVE ASSEMBLIES INCORPORATED IN ARVINMERITOR AXLES, PART NOS. 110700 AND 110800, THERE IS A RECESSED AREA ON TOP OF THE VALVE IN WHICH A BRASS GUIDE PIN FITS DOWN INSIDE THE BODY OF THE VALVE AND IS HELD IN PLACE BY A STEEL SNAP RING. THE RECESSED AREA ALLOWS ACCUMULATION OF WATER, DIRT, AND/OR CHEMICALS TO BUILD UP BEHIND THE SNAP RING TO THE POINT WHERE IT WILL NO LONGER CONTAIN THE GUIDE PIN RESULTING IN A FAILURE OF THE AIR VALVE.

RiskFAILURE OF THE VALVE IN AN EMPTY OR LIGHTLY LOADED TRAILER WHILE THE VEHICLE IS IN MOTION COULD RESULT IN A HARD APPLICATION OF THE SPRING BRAKES, POSSIBLY LOCKING UP THE TRAILER WHEELS AND RESULTING IN A VEHICLE CRASH.

FixSEALCO WILL PROVIDE A REPAIR KIT AND INSTALLATION INSTRUCTIONS TO CUSTOMERS FREE OF CHARGE. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT SEALCO AT 602-253-1007 OR WABASH AT 765-771-5404.

VEHICLE DESCRIPTION: TRAILERS EQUIPPED WITH CONMET PREGREASED TRAILER AXLE HUBS. 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.

RiskAN OUTBOARD BEARING FAILURE CAN RESULT IN A SEPARATION OF THE HUB ASSEMBLY FROM THE SPINDLE.

FixCONMET IS CONDUCTING THE OWNER NOTIFICATION FOR THIS CAMPAIGN. 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 MAINTENANCE CAN BE PERFORMED AND THE HUB REINSTALLED. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CONSOLIDATED METCO AT 1-800-425-4827 OR WABASH AT 1-765-771-5440.
