How do I correct a slight occelation

harry palmer said:

My bike got a puncture and I had to remove the rear wheel
to replace the inner tube. When I had remounted it and
reset the brakes and gears I ran it on the bike rack to
see if all was ok, it wasn't. When I let it coast I notice
a slight oscillation in the rear cog assembly. It seems to
move about 1/8 inch left to right as the wheel coasts. The
wheel itself seems to be true and also the axle appears to
be straight. anyone know what might cause this and how I
correct it??

Thanks in advance.

Sounds like you did NOT put the wheel back on straight.
Loosen the quick release, then while putting pressure on the
rear wheel, by pushing on the saddle for example, engage the
quick release back. Hope this is all your problem...

I'll try Zilla but I don't understand how it is that when I
look at the wheel rotating it isn't oscillating at all.
It's going around straight as a
die. If I had the axle off center wouldn't it make the wheel
appear to wobble?

They just do this, can't tell ya why, but its OK. Grab a
buddies bike, pick up the back wheel, and give it a spin.
More than likely his cogs will wobble back and forth too.

Cheers, Shawn

Are you sure it's not the ramped teeth on the cogs that
appear to make it wobble? The teeth aren't cut straight and
true; they 'wander' from left to right and back to help pick
up the chain. If you're just looking at the teeth, it will
look like a wobble. You need to look at the cog below the
teeth to tell if it's wobbling.

You don't. The wobble you noticed is called "Bearing
Precession'" and it normal. You probably just hadn't noticed
it before. Higher quality freewheels and freehubs show less
precession, but it is still there. Even high quality
navigation gyroscopes have some precession.
