AS A RESULT OF SEVERE SHOCK AND VIBRATIONS, THE BRAKE SPIDERS ON THE INVOLVED VEHICLES MAY DEVELOP CRACKS NEAR THE CAMSHAFT MOUNTING BOSS. THE CRACK PROPAGATES ACROSS THE SPIDER UNTIL THE CAMSHAFT BOSS IS COMPLETELY SEVERED FROM THE REMAINDER OF THE SPIDER. WHEN THE CAMSHAFT BOSS HAS COMPLETELY SEVERED, THE S-CAM, S-CAM BRACKET, AIR CHAMBER AND SLACK ADJUSTER CAN FALL AWAY FROM THE BRAKE SPIDER RESULTING IN A "NO BRAKE" CONDITION ON THE WHEEL.
Consequence & remedy
Consequence: Not supplied
Remedy: THE DEALER WILL REPLACE THE FRONT BRAKE SPIDERS ON ALL AFFECTED VEHICLES USED IN SNOW PLOW DUMP AND REFUSE HAULING APPLICATIONS. THIS WILL BE DONE AT NO CHARGE.
THE FUEL SEPARATORS ON THE INVOLVED VEHICLES MAY HAVE THIN WALLS DUE TO A MATERIAL THICKNESS PROBLEM. THE SEPARATORS IN THESE WALLS MAY CRACK AND MAY ALLOW FUEL VAPORS OR LIQUID FUEL TO LEAK INTO THE ENGINE UNDER HIGH PRESSURE CONDITIONS.
Consequence & remedy
Consequence: Not supplied
Remedy: THE DEALER WILL INSTALL IMPROVED SEPARATORS AND RELOCATE BOTH THE SEPARATOR AND FUEL CANISTER WITHOUT CHARGE.
THE PARKING BRAKE LEVER MOUNTING BRACKET MAY BEND AND BREAK DUE TO REPEATED APPLICATIONS OF THE PARKING BRAKE. THIS WILL CREATE A TEARING FORCE AT THE BOLT MOUNTING AREA OF THE BRACKET.
Consequence & remedy
Consequence: Not supplied
Remedy: BENT OR CRACKED MOUNTING BRACKETS WILL BE REPLACED AND A REINFORCEMENT STRAP WILL BE ADDED TO LIMIT THE "LIFT AND PULL" FORCE ON THE BRACKET. THIS WILL BE DONE WITHOUT CHARGE TO OWNER.
THE VAPOR SEPARATOR IN THE FUEL TANK EVAPORATIVE OMISSION SYSTEM LACKS THE CAPACITY TO PROHIBIT LIQUID GASOLINE FROM PASSING TO THE CANISTER UNDER CERTAIN FUEL EXPANSION CONDITIONS. GASOLINE WOULD BE DISCHARGED FROM THE BOTTOM OF THE CANISTER ONTO THE REAR OF ENGINE, CREATING A FIRE HAZARD.
Consequence & remedy
Consequence: Not supplied
Remedy: DEALER WILL INSTALL AN ADDITIONAL FUEL SEPARATOR TO ENLARGE CAPACITY, AND ADD A DISCHARGE HOSE TO THE BOTTOM OF THE FUEL CANISTER.
THE INVOLVED VEHICLES MAY CONTAIN A POOR QUALITY OR AN INSUFFICIENT WELD OF THE BRAKE GROUP MOUNTING FLANGES TO THE AXLE HOUSING. THIS COULD LEAD TO THE FLANGE BREAKING LOOSE FROM THE HOUSING, ALLOWING THE BRAKE GROUP TO TURN WITH THE BRAKE DRUM ON BRAKE APPLICATION. THIS WILL CUT THE BRAKE LINES TO THE BRAKE GROUP AND MAY CAUSE PARTIAL LOSS OF BRAKING CAPABILITY.
Consequence & remedy
Consequence: Not supplied
Remedy: DEALER WILL REWELD THE BRAKE FLANGES CORRECTLY, WITHOUT CHARGE TO OWNER.
THE DEFICIENCY EXISTS IN THE FRONT AXLE FORGED ALUMINUM HUBS. THE DEFICIENCY WHICH IS IN THE BARREL SECTION BETWEEN THE INNER AND OUTER BEARING, MAY RESULT IN CRACKS WHICH COULD LEAD TO HUB FAILURE. WHEN HUB FAILURE OCCURS, THE SEPARATED HUB IS RETAINED ON THE AXLE SPINDLE BY THE WHEEL BEARING AND ADJUSTING NUT.
Consequence & remedy
Consequence: Not supplied
Remedy: THE DEALER WILL REPLACE THE FORGED ALUMINUM HUBS WITH STEEL HUBS, AT NO CHARGE.
THE STUB ENDS OF THE AXLE HOUSING MAY NOT HAVE BEEN PROPERLY MANUFACTURED TO SPECIFICATIONS. THESE STUBS WOULD BE OF INADEQUATE STRENGTH AND COULD FRACTURE. COMPLETE FRACTURE WOULD CAUSE THE FRONT WHEEL, HUB, AND BRAKE ASSEMBLY TO DETACH FROM THE AXLE.
Consequence & remedy
Consequence: Not supplied
Remedy: THE DEALER WILL INSPECT AND, IF NECESSARY, INSTALL THE CORRECT AXLE HOUSING STUBS.
