2003 NISSAN FRONTIER Wheels Problems

WHEEL BEARINGS KEEP BACKING OFF SPOKE WITH OTHER PEOPLE WHO OWN A FRONTIER AND THEY HAVE SAME PROBLEM THIS IS A SAFTEY ISSUE HAVE TO TIGHTEN THEM REGULARLY

I NOTICED A NEW SOUND WHICH I THOUGHT MIGHT BE A STUCK CALIPER, YESTERDAY. THIS MORNING I DROVE TO MY AUTO GARAGE TO GET IT CHECKED AND JUST AFTER LEAVING THE HIGHWAY AND A BLOCK BEFORE THE GARAGE THE DRIVER SIDE WHEEL FELL OFF! THE GARAGE CHECKED IT REPLACED THE LUG NUTS WHICH HAD ALL LOOSENED SPONTANEOUSLY AND FALLEN OFF. THE VEHICLE WAS MOVING AT A WALKING PACE, TURNING TO THE LEFT WHEN THE WHEEL SEPARATED. *TR

I HEARD A SUDDEN THUD AND THEN A GRINDING NOISE COMING FROM THE REAR END AS IF A BRAKE HAD HUNG UP,METAL TO METAL.WHEN I EXITED THE VEHICLE THERE WAS SMOKE COMING FROM THE REAR OF THE VEHICLE AND A VERY STRONG SMELL OF OVERHEATING OF THE BRAKES OR METAL AND FLUID.UPON PULLING THE WHEELS,OUR COMPANY MECHANIC FOUND NOTHING OF THE SORT TO BE WRONG. I CALLED A FRIEND TO HAVE THE VEHICLE TRAILER-ED TO MONRO MUFFLER AND BRAKE IN MANSFIELD PA,WHERE IT WAS DETERMINED THE BEARINGS HAD FAILED IN THE REARS,BOTH INNER AND OUTER. NISSAN USA DETERMINED THAT MY VIN # DID NOT FALL INTO THE RECALL CAMPAIGN EVEN THOUGH IT FELL WITHIN THE SAME MAKE,MODEL AND YEAR WITHIN RECALL CAMPAIGN #02V299000! NISSAN ADVISED ME TO TAKE THE TRUCK TO WILLIAMS NISSAN IN SAYRE PA AND HAVE IT DIAGNOSED THERE. I HAD PREVIOUSLY CALLED THEM BEFORE CONTACTING NISSAN USA...
