I posted about a week or so ago, with a bad vibration that became noticeable at 80 mph and got progressively worse with increasing speed. The problem was a bent rear driveshaft, the runout in the middle was about
.042 in, spec is .015 or less. It is now smooth as butter up to 100, haven't had it any faster yet. Thought I would post this for you all out there that may be chasing down that annoying vibration. I got a driveline shop here in Chattanooga to make me a custom shaft with thicker walls, it is a very nice piece and I am glad I found this little glitch before my power grows. Jay

 

Thanks for the info!

 

How much did you spend if you don't mind me asking....
