I did a search and could find very little on this topic. I have been trying to determine what is causing the vibration on my Tacoma at around 60mph.

I have been blaming the tires, but I want to rule out other possibilities. I am pretty sure it is not the rotors. It seems to brake OK.

From reading posts here, some have indicated driveshaft issues as a cause.

This weekend I got under the truck and poked around. I couldn't determine much. I wasn't too sure on what to look for. I looked at the drivehsafts and the u-joints, I wiggled the driveshafts around, especially at the joints. Nothing seemed out of the ordinary-to me anyway.

I also wiggled the driveshaft at the center support bearing and there is some freeplay. It moves around noticeably in the rubber insulator. Could this be the problem? I have no idea how much freeplay should be there. Is some freeplay normal or should it be tight without hardly any at all?

Any advice is greatly appreciated.

Somebody's got to know the answer.
