If it is a wheel bearing they aren't too hard to change but you need a big puller to get them out. If the wheel bearings are really trashed though your axles my be toast also.
Unfortunately on the 8.8 rear Ford adopted chevy's bad idea of using the axle as the inner bearing race so if the bearing goes often the axle goes with it.
To change the wheel bearings you have to take the axles out.
If you search on youtube you will hit some videos on rebuilding the 8.8 rear, they'll show how to take the axles out. You need to take a close look at your diff also.
Thanks I really appreciate it!
