Hey, Jason Pfeifer, Shimano tech guy....

Jason,
I have a not very old 7800 rear hub with rough bearings in the freewheel
body. I got new bearings for it but getting the old ones out is confounding
me. I'm not new to replacing bearings, just not in that particular
application. Is this thing even supposed to be serviceable or is it one of
those expensive throw away deals?

I looked at the exploded views but they don't explode the freewheel body.
