VEHICLE DESCRIPTION: MOTOR HOMES. MISALIGNMENT OF THE MOTOR HOMES' FRONT BRAKE HOSES DURING SHARP TURNING MOVEMENTS CAN WEAKEN THE HOSES THROUGH RUBBING AND/OR CHAFFING ON THE STEERING TIRES OR COMPONENTS OF THE FRAME. A SUDDEN LOSS OF BRAKING ON A STEERING WHEEL COULD OCCUR IF THE HOSE RUPTURES, CAUSING THE MOTOR HOME TO PULL SHARPLY TO ONE SIDE.
CERTAIN MOTOR HOMES FAIL TO COMPLY WITH REQUIREMENTS OF FMVSS NO. 120, "TIRE SELECTION AND RIMS FOR MOTOR VEHICLES OTHER THAN PASSENGER CARS." THESE MOTOR HOMES WERE ERRONEOUSLY ASSIGNED INADEQUATE TIRE INFLATION PRESSURES AND INADEQUATE AXLE WEIGHT RATINGS ON THE FRONT AND/OR REAR AXLES AS A RESULT OF MATHEMATICAL MISCALCULATIONS. THESE MOTOR HOMES HAVE TIRE WEIGHT RATINGS THAT ARE LESS THAN THE FRONT OR REAR AXLE WEIGHT RATINGS (FRONT AXLE WEIGHT RATING:FAWR AND REAR AXLE WEIGHT RATINGS:RAWR) AND IN SOME INSTANCES HAVE INADEQUATE FAWR AND/OR RAWR.
VEHICLE DESCRIPTION: MOTOR HOMES EQUIPPED WITH DANA STEERING RELAY LEVERS. THE LEVERS CAN DEVELOP SURFACE CRACKING.
