The vibration was noticed while driving between 10 and 45 miles per hour. After 50 MPH the vibration disappears.
With only 1,780 miles on the motorhome (770 was already on when we purchased)I had the U joints and carriers checked by a mechanic and all was well.
The motorhome has never been on anything but blacktop or concrete roads. I would think it was a balance weight either misplaced or came off.
The mechanic suggested having the drive shaft rebalanced but that is the problem. Nobody in the area does the 3 pieces drive shaft together, so my question was can it be done successfully one piece at a time?
