If you have a jack wheel, it mounts on the lower end of the jackstem, of course. But there are at least two configurations of this jackstem end, and the wheel that fits one will not fit the other. One has a clip or pin, one has a groove with a bend at the top. We had a discussion about this, perhaps a year ago? Anyone? Maybe this?

And don't you have a power jack? That would be yet a third configuration.
In other words, these things appear not be one size fits all, so be sure you know and get what you need.
