I believe the truck needs the front axles to keep the bearings together. At least thats what I have been told. Could be wrong. But the newer dodges have 4wd wheel bearings in the front of 2wd models. At least my 04 does. It has axle splines and everything but its 2wd. So I am not sure if they where just designed that way to cut costs. I would take the spline end of the shaft and assemble it in the wheel bearing. If it has ABS the ring will be on the CV shaft and will throw codes as well.
