Most likely. Replacing the front hubs isn't too difficult, but you should replace both at the same time. I remember replacing one of mine that I suspected was bad and they both ended up needing replacement, so it made sense to just do them both.
I think the rule for bearings is that whichever direction you turn that you hear the noise, it's the opposite side which needs replacement, so if you hear a noise while making a right hand turn, it's the left bearing. On my vehicle I heard a noise only when making left turns, but both bearings needed replacement
