well, what if its the rear joint? drive shaft one foot long--2 ft circlex Pi(3)=6 foot per rev x 6000=36000 minutex 60 min divided 5280 = one hell of a whack

Oh, and since the shaft is about one foot long the force will be equal to your torque/horsepower numbers on your precious dyno sheet

Make it straighter, stronger, better and then cover it up and drive carefully
