Bearing rumble

either too tight or bearings shot. check out sheldon's site for correct
adjustment.

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.
