Came across a used Wii recently and found that it sometimes had trouble taking in discs; it will take it in about halfway, not go any further and then eject. Opened it up to clean it out and one of the springs in the drive assembly (the top metal part with all the white plastic parts) is completely gone. This causes the pole in the center of the drive to not return completely to its original position. Tried to lubricate it and try using something else to act as tension so it would return but it still isn't working; even if it does take discs it still stalls while pulling it in and sometimes doesn't return to its original position at all. Is there something I could do to fix this or is the drive just shot? It's a GCN/Wii reader so I'd like to save it if possible.
