Truck is finnaly all finished, with the exception of the new cam, running and driving great at lower speeds. When I break 2000 rpm in 5th (speedo not hooked yet, about 60mph) I get a vibration that increases with speed, nothing below that, tires were just balanced and it doesn't come from the motor so I'm thinking driveshaft, could this be from the u-joints being off angle, or is it most likely the driveshaft out of balance? any experience with this? if it is the later, how can I set up a fluid balance in my driveshaft? I heard this would work. I have a one piece shaft. Any guess on a price for getting it balanced? Thanks for the help!
