So my machine was dragging a little on the y axis, only going to the right. It would bind and catch going to touch the bit plate. I figured it was the truck bearings, and I was partly right. I replaced the bottom bearings as they were a little sticky, but not frozen solid. The top bearings were fine, spinning freely. The new rails are clean and free of pitch and packed dust. The truck moves freely on the rails with the belt off. When I install the belt it fetches up again only going to the right. I checked the tensioner also and that was sticky but not frozen solid. I also took that apart, cleaned and dry lubed it so it spins freely. So I am assuming the y motor needs to be replaced. I have read here that the shaft and bearings wear out leading to this problem. With almost 300 cut motor hours its probably the problem. I am just looking for confirmation from more powerful minds than I. Thanks in advance.
