Alternative to stethoscope?

[minux]

Trying to find a noise in the senator, would prefer to just not replace every bearing/pulley on the car. Are there any alternatives I can use to sourcing a noise without the use of a stethoscope? One of the bearings is whiny/noisy, just not sure which one(or two or three or four ).

Any tips?

Thanks

Have you tried taking the belt off and spinning them by hand individually? I did this when i had a noise, turned out to be the waterpump, became quite evident when spinning them individually by hand, both in the noise and the feel.

Another method which i have seen used it a long shafted flatblade put onto the hub of each pulley while the accesory is under load, which may pick up a noise that isnt evident by a low speed, hand spin. I havent done this personally, but im sure on the internet it will point you towards the exact technique.

Keep the alternatives going.
