Are the needle bearings what the axle shaft run on? Located behind the upjoints?

Yep. All they do is support the weight of the axle stub. Pull the hub assembly and the needle bearings can be replaced from the backside.

Its a how-to on replacing the ball joints, but points 1-11 in the second post are the same as getting to the needle bearings. There are also photos associated with the thread.
