Gq patrol clutch

[Newbiee]

Hi fellas,

Replaced the clutch on the weekend in the wagon, td42,

Replaced it with a hd 4terrian clutch everythings good, clutch presure the way it engages an disengages is spot on but, when idling it makes a weird vibrating noise like a growling noise, but when i engage the clutch its fine i can release it an the noise is gone? I replaced the release bearing an the spline of the gearbox was not hanging off the clutch plate when installing the box, so i dont think it could be a bent clutch plate, any ideas really dont want to take the box of again!
