Thread: 53 Is back from the Body Shop

Tweet

I'm starting to think I'm barking up the wrong tree and something else is the problem. The engine to 3.5 down so I put the pinion at 3.5 up and it was noticably terrible in the back. The yoke coming out of the trans was nearly straight and yoke on the rear end was way crooked and I put the Tremec angle app on there and it gave me all kinds of red flags. So then I thought maybe I need to do more math. I took the motor deg and subtracted the drive shaft angle and matched the rear end to that angle and nope, same vibration. If I put the transmission in neutral when the vibration is going on, nothing changes , at least I don't think it does, but I'm doing 80 MPH runs on a black top looking for cops so these are not long-term tests lol. I think it may be a little bit worse tonight, and I have the rear end pointing down more. I'm thinking about giving up on measurements and just angling it little bits at a time and driving it everyday to see if it gets better or worse. Maybe there is just that much driveline transfer from the frame to the cab, I don't know.

Ryan, it is a slip yoke output, I was checking that out tonight, it's maybe a little loose, I'm not sure how to tight their supposed to be.
