Wodent wheel not so silent?

[Drago]

I recently purchased a second hand wodent wheel for my mice, and it was quite silent at first, but now seems to be making the most horrendous noise I've ever heard! I've tried oiling it, but that only worked for a short time. It sounds almost like nails on a chalk board and I can only imagine it's bothering my little mice. Has anyone experienced this problem, or have any tips regarding what I should do with it?

I've never had a wodent wheel so I can't be any help there, but the noise sounds terrible (it's sounds like the sort of noise where i always cover my mouth to protect my teeth for some reason lol) :S I think there are plenty on here who have/had wodent wheels so hopefully someone will have a soltuion.
