PS1/2 PS2 Magnet Help

[Windaga]

Hey guys, I've just got a quick question;

I opened my PS2 earlier today in order to try swapping out the discs. (As opposed to removing the cover of the tray - stupid, I know : ( )

I removed the PS2 cover, and then the cover to the drive. The Drive has this little plastic piece, which I now know is referred to as the Magnet hub. I removed the hub from the black, plastic drive cover and placed it on it's spot in the PS2. However, I can't get the magnet to stay in the center of the PS2 magnet - when the PS2 runs, the hub wobbles, and it the disc cannot be read. So I placed the hub back into the black plastic drive cover (where it was originally), and now no disc can be read. I need help :/.

Late response, but posibble upside down? metal washer sides face up, plastic sides faces the disk
