1999 FORD E-350 Wheels Problems

I RECENTLY PURCHASED A USED 24' 1999 WINNEBAGO ITASCA SPIRIT WITH VERY LOW MILEAGE AND AT THAT TIME I NOTICED A SHAKING OR VIBRATION PROBLEM POSSIBLY COMING FROM THE TIRES. I OWNED A MOTOR HOME IN THE PAST AND HAVE SOME EXPERIENCE. THIS MOTOR HOME SAT FOR SEVERAL YEARS SO I ATTRIBUTED THE SHAKING TO THE MEMORY IN THE RUBBER OF FLAT SPOTS ON THE BOTTOM FROM SITTING FOR A LONG TIME THAT USUALLY SMOOTH OUT WHEN DRIVEN ESPECIALLY AFTER 30 OR 40 MILES ON A WARM DAY, BUT AFTER A 400 MILE TRIP IT DIDN'T SMOOTH OUT, IN FACT IT SEEMS TO HAVE WORSENED. BEFORE PURCHASING IT FROM A PRIVATE PARTY I RAN AN INSTAVIN AND CARFAX REPORT AND ONLY DISCOVERED AN UNCOMPLETED NHTSA RECALL #05S28 ON THE SPEED CONTROL ONLY. I THEN SEARCHED SEVERAL FORUMS AND DISCOVERED MANY, MANY REPORTS OF THE SAME PROBLEM WITH THE SHAKING AND...

TL*THE CONTACT OWNS A 1999 FORD E-350. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE CONTACT NOTICED THAT THE REAR OF THE VEHICLE WAS LOW. THE CONTACT STOPPED AND INSPECTED THE VEHICLE BUT COULD FIND NOTHING WRONG. WHEN SHE REACHED HER RESIDENCE, SHE SAW THAT THE DRIVER SIDE REAR TIRE LUG NUTS HAD RIPPED OF THE WHEEL AND FRACTURED THE RIM. THE VEHICLE WAS NOT INSPECTED BY A DEALER OR REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 141,000.
