Try to picture the speed of the components related to a gear change, then associate the noise/speed with the component. Does the sound match the engine speed, the input shaft speed or the difference between the two? A pilot bearing will usually make noise as the clutch disc slows to rest when shifting into gear when stationary (difference between the two). A throw-out bearing noise will match engine speed. A mainshaft bearing noise will match the speed of the selected gear (i.e. upshift/downshift)
