Only about half of the bearing rides on the macheined area.Old axle machined area from back of flange is 3.291 in.a nd the new ones were only 2.785 in. Any suggestions?

Thank you for your response. I have thrown that idea around. It's driving me crazy that no one, even the axle manufacturers, can answer the question why the machined areas are so different.

I found a manufacturer that has axles that have the machined area (race) extended another 2 inches on the axles. Once I got the axles I double checked the position the bearing ride on the axle. I have approximately 1 in left. So far so good.
