I have 2005 corolla with a 1.6 zzfe engine, whenever the car goes above 3000 rpm, a resonating grinding sort of a sound starts coming from the engine, its not bearings as the sound is present even when the car is standing, a technician told me its from the axles but i am not convinced as the axle boots seems fine, can there be any other sources for this sound?
It there a way to diagnose it?
