I would add to BobG's excellent suggestions. I would get the tool, remove the freewheel, repack the hub bearings, and apply anti-seize lubricant to the hub threads prior to reinstalling the freewheel. The only freewheels I've ever had trouble with are one's from the 70's or 80's that have never been removed. Stubborn freewheels can be removed by putting the spline tool in a vise, putting the wheel on top of it, and turning the wheel counter clockwise like you are steering a bus to the left. Otherwise, I just put the tool in the freewheel with the quick release lightly screwed against the tool to hold it in place. I then put a 12" adjustable wrench on it and give it a whack with a dead blow hammer enough to free it before removing the quick release.
