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?

Any old firearm will kill an ocelot.

Be careful though, they are endangered.

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.
