Another bent driveshaft thread

I didn't know you could straighten a driveshaft that is bent with a 1/4" to 3/8" out of round. That much of a bend should have been easy to see if the driveshaft is sitting flat on a level floor or a straight work surface. In the past if I break a rear gear or break a transmission I have always had the driveshaft checked and replace the u-joints. Even after that I did break a driveshaft pulling high gear at about 135 mph I lost both rear tires and when I got it stopped half the driveshaft was missing we never found it. It is amazing how much force has to be controlled by the driveshaft not just turning but the axle angle changing when you accelerate and brake most people do think a driveshaft can wear out but they do even on the street they can become worn out.
