1999 Wabash Trailer problems

Defect

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.

Consequence

FAILURE 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.

Remedy

SEALCO 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.

Defect

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.

Consequence

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

Remedy

CONMET 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.

Defect

VEHICLE DESCRIPTION: TRAILER AXLE SUSPENSIONS INSTALLED ON WABASH NATIONAL TRAILERS WERE ASSEMBLED WITH INCORRECT BRAKE CAMSHAFTS. THESE TRAILERS WILL NOT COMPLY WITH THE DECELERATION OR PARKING REQUIREMENTS OF FMVSS NO. 121, "AIR BRAKE SYSTEMS."

Consequence

THE BRAKES WILL NOT FUNCTION PROPERLY. THESE TRAILERS WILL ALSO HAVE DIMINISHED STOPPING DISTANCE PERFORMANCE AND REDUCED PARKING (HILL HOLDING) CAPABILITY.

Remedy

THE TRAILER OWNERS (JB HUNT) WILL INSPECT THE AXLE SUSPENSIONS AND CORRECT THE BRAKE CAMSHAFT CONDITION.

Defect

VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH BRAKE VALVES MANUFACTURED BY HONEYWELL BENDIX. THE ORIENTATION AND LOCATION OF THE BRAKE VALVE IS SUCH THAT WATER CAN GET INTO THE VALVE THROUGH A VENT IN THE VALVE. THE WATER WILL CONTAMINATE THE AIR SYSTEM AND COULD FREEZE THE BRAKE VALVE.

Consequence

IF FROZEN, THE OPERATOR WILL NOT BE ABLE TO MODULATE THE BRAKE FORCES WITH THE BRAKE PEDAL.

Remedy

BENDIX IS CONDUCTING THE OWNER NOTIFICATION FOR THIS RECALL. OWNERS ARE INSTRUCTED TO CONTACT BENDIX AT 1-800-478-1793 TO RECEIVE A REPLACEMENT UNIT.
