So as I thought I was about to wrap rally prep on the truck tonight I found something troubling. So here’s the deal. The drive shaft is pulled backward stretching the carrier bearing instead of slipping at the slip yoke. It’s a brand new slip yoke but I had a hell of a time putting it together. The driveline shop that shortened and balanced this thing told me someone had stripped the blue coating off the splines and it needed replaced. Granted there was no coating on the splines but it felt rock solid. They wouldn’t cut and balance without doing it so I let them. They just replaced the male end. This was an aftermarket shaft I bought off a guy local so I don’t know if it actually was supposed to be coated or not. It will not slip. I beat it apart with a BFH far enough to bring it to length but I’m essentially running a 1 piece because it won’t slip. I can try to press it apart and hope the carrier bearing is okay (or replace it) or I can use this as an opportunity to upgrade. Hence the title. It seems like I’ve seen longer wheel base pulling trucks use single piece shafts. Does anyone know the “accepted length limit” on a 1 piece? I’d have to measure to see what it needs to be. I don’t remember anymore.
