Rotational Squeak

Hey everyone so I’m having a little problem with my car. So I’ve had a weird rotational squeak coming from the engine bay and at first I thought it could be wheel bearings so I changed them and that didn’t fix it. I tested to see if the dust guards were rubbing on the brakes which they are not. Doesn’t seem to be coming from the drive shafts so I’m a bit stumped. The squeak gets faster as the car goes faster and only seems to happen under load as I had the car running up in the air and couldn’t hear the squeak then. It sounds like the same sort of squeak you get from a belt but it’s not.

thanks

Could be a belt tensioner bearing ? Have you a stethoscope to narrow it down, you can make 1 with an old set of headphones and a skewer. Not as good but works lol

Could it be the tensioner belt if it only squeaks when moving? Ok I’ll see if I can get a stethoscope but like I said it’s hard to isolate the noise as it’s only happening when moving.

It could take whatever it is to get to a certain rpm to start making noise or have a load on ie driving
