Vibration in drive shaft.... replaced u-joints
Alright, got an 06 f250 8ft bed, extended cab. Had a vibration in the truck from stop to about 15-20mph. suspected U joints in drive shaft. Could hear squeak driving slow, sounded like normal u joint failure noise associated with minor vibration.
replaced u-joints in drive shaft(2 piece shaft with center support bearing) still have original center support bearing, which seemed in good shape after pulling the drive shaft out, spun easy . no play.
after replacing the U Joints in the drive shaft. i NOw have a much worse vibration. This is the first time i have dealt with a 2 piece shaft. Now sure if u joint replacement would/should warrant getting the drive shaft balanced now>?
Definitively have a vibration in the truck now, goes away at 55mph. strong below that.
