Loud whine! Please help!

[HamzaZaid]

Hello guys,

Recently I have been hearing this horrible whine coming from my 12' Raptor. I have no idea where it's coming from though, I can't seem to find the source..

Here's a link to what it sounds like (not my video, but similar sound)

and it only happens when car is on D and the braked is applied, if I raise the RPM it goes away completley.

Could it be the CAI?

CAI a real possibility, was camera up near the CAI filter? Try same shots with filter off. If not, it could also be power steering pump.

One of the idler pully's? It will do that if you soaked it in water for a period of time.

Yes, possibly a pulley
