Strange noise in GQ front end

Hi all
I have an intermittant noise coming from the front right wheel area . This noise is similar to metal to metal brakes but more like rubber to rubber (this is the only way to explain it) it happens mostly when coming to a stop aprox 20kph and then continues up to about 60kph but seems to go away when turning right . The noise when moving very slow Ie: in the garage at home sounds like th tyre is flat but that was the first thing i checked . I have checked the brake pads and disc guard but they are fine and there is nothing stuck between the disc and guard .there is also no oil leaks at all.
Could someone please shed som light

Thanks
Steve
