I had a slight vibration on our MH coming back from Fl last year and I blamed it on the roads in ILL> then further along after we got home I winterized and took it for one more little ride before it went to storage and the vibration bothered me that night which made me look further the next day-the 4 bolts on the front of driveshaft were 2 gone- one snug- and one tight-Had a bugger of a time finding the right bolts, had to go to Ford dealer with vin number to get them-When I remove them I made sure driveshaft didn't turn so everything went back together in the same place--Couldn't check it out on road test because cover was on already-find out Apr 1st when we head for FL but I am sure that was the vibration--Rich
