This is all to to me as well, I can't say I know the answer to that, wish I did though. When I turned the soleplate I noticed the squeak. I did like I said and noticed the squeak went away. At that point I was happy and unfortunately I didn't really pay attention to how freely it spun. I am going to need to do some maintenance here soon as I'm starting to hear the squeak again, its not as bad , but its there. It could be just in need of some cleaning.
