I WAS TOWING OUR GOLF CART USING THE 2006 CARRY-ON TRAILER. I HAD JUST TURNED ON TO A PAVED SIDE ROAD. I HEARD A SQUEAL AND THOUGHT IT TO BE MY CAR. I MAYBE TRAVEL SLOWLY A 1000 FEET WHEN I HEARD THE TRAILER HIT THE PAVEMENT AND THE WHEEL OF THE TRAILER ROLLING TOWARDS OUR CAR. THE WHEEL JUST MISSED THE BACK OF THE TRAILER. THERE WAS DAMAGE TO THE TRAILER AND REPAIRS WILL HAVE TO BE MADE.. FURTHER INSPECTION OF THE WHEEL AND AXLE, WE DETERMINED THAT THE WELD HAD MADE A CLEAN BREAK AND ALLOWED THE WHEEL AND HUB TO COME OFF. I CONTACTED CARRY-ON. THEY SAID THE TRAILER WAS NO LONGER UNDER WARRANTY. ( I KNEW THIS) POORLY MADE EQUIPMENT SHOULD ALWAYS BE LOOKED INTO. CARRY-ON HAD NO IDEA WHO MANUFACTURED THE AXLE FOR THAT YEAR. THEY WOULD NOT GIVE US ANY HELP AT ALL. I COULD ONLY FIND A STAMP ON THE HUB THAT LOOKS LIKE THIS CEI AND A PART NUMBER A0829. WHEN I LOOKED IT UP IT IS AN AXLE THAT IS AVAILABLE FOR SALE.FROM TRICAM, BUT IT DOES NOT LOOK LIKE OUR AXLE. WE HAD JUST COME OFF FROM I-69. COULD HAVE BEEN A VERY DANGEROUS SITUATION.
