I recently picked up a Sachs LY96 7 speed freewheel in very nice condition but it doesn't make any noise. It spins freely and seems to work okay but there is only the faintest click if you really listen for it.

Any idea if this is normal for this freewheel or if it is something I should be concerned about?

I'd like for it to make a little noise so I may break it open to see what's going on. Won't mess with it though if this is normal operation.

Thanks!
