[Shotimes] Vibration or picky...again

[cmichaelo@optonline.net]

Ian,

I don't get it.  What might happen when I pull on the hub?

The hub and bearing are held firmly in place onto the spindle by the hub nut. So I don't see what can be discovered by pulling straight out.

So maybe you mean pulling to the side or up to see if the hub moves?
