Subaru Other

I have a 2001 Subaru Impreza. I've noticed that the wheel bearing needed to be replaed for about a month now, but I barely drive the car. I took it up to a mechanic who said I had to replace the end Wheel Hub, not just the bearing. Is this true or is he just trying to get an extra few hundred bucks out of me?

Front is a " press in bearing" Rear is probably a hub and bearing assy.

You have to trust where you go. Or go elsewhere.
