Bad freewheel?

[Old Tom Crowther]

I just mated a 7 speed wheel with my old 10 speed and have noticed that the freewheel is wobbling in driven mode only...not so much when coasting. Ideas?

Thanks. It turned out to be a bad cassette (its not a freewheel).
I installed a new one and it is now running true.
