The frame could be sprung or misaligned from the factory enough to do that even if you carefully centered the rear bolts in their respective holes. There's lots of room for slop here to make it work. Also remember that you may have to shim the front motor mount to get the u-joint angles equal if you have an open drive line. It the angles aren't equal the u-joints will fight each other and vibrate. Spicer spec. is 1 degree for trucks 1/2 degree for motorhomes. Shim accordingly.

Thank you 1tontommy and buoyermaker for the information. I will try loosen the rears and try to shift the front.
