Sqeeking sound?

[Chamelion]

Hello,

Had my 02 AUIII falcon wagon for a week and a half now and it has developed a squeeking sound.
It's seems to be located around the front drivers side wheel and is most noticeable between 40 and 70km/h.

My first thought was the hubcap/wheel cover as I've had it happen in another car, but some WD40 doesn't seem to have helped at all.

The car is still under statutory warranty until Janurary and I'll be getting my mechanic to look over it about this time next week, but in the meantime any chatter about what it could be would be appreciated.

Cheers

Matt.
