Something I learned today, Need advice.

There is no inner wheel bearing in a 7 1/4 rear end unless you want to call the carrier bearings an axle bearing but it really isn't. You'd have to pull the rear end apart to change those. When you pull the axles, grab the axle bearing with one hand and rotate the axle with the other. If you feel any kind of hitch at all or hear any noise, the bearing needs to be replaced.
