should fix it. if not, the bearings are the problem.

My rear bearing rumbles a little. Wheel doesn't wiggle,
so I assume it's a little tight. Is that correct? Or is
there something more nefarious going on in there?
Assuming it's just tight: It's being used with a quick
release, so I figure I ought to build it a little loose
before installing. Is there a standard amount to back
off (like a quarter turn or so) or is this a trial and
error thing?

Trial and error. But more likely than being tight your noise
is caused by dry bearings or just plain worn out hub. Get in
there and clean, regrease, perhaps replace bearings and
cones. How many miles on this thing?

It's a mystery. This is the beater I found in the attic.
At the time I first fixed it up I didn't have much time
and even less money, so for the bearings all I did was
back 'em off, squirt in a bunch of grease, put 'em back
together, and pray a lot. (: I'm taking it apart now.
BTW, if I have to buy some new bearings, what, exactly,
do I ask for when I get to the bike shop? Just "hub
bearings" and however many balls it has?

When you take the wheel apart, clean all the grease off and
check for cone pitting. If the cones are pitted you will
need to bring them to the LBS so they can be matched up
since there are a million different cone styles. Sometimes a
cone has only a few pits in one spot and as an emergency
measure you can reassemble the wheel so that the pits are on
the top where there is no load. Grease and reassemble the
wheel with new balls and just enough preload to prevent
wheel slop.

Ooh, yeah, they're shot. The races in the hub are still
smooth, but one cone looks like the grease was
contaminated, and the other looks like it was either out
of round, or a few balls were bigger than the others.
Guess I'll overhaul the front and BB while the bike's
apart since I figure they're probably in similar shape.
