Main Bearings : Main bearings are located inside your engine. They are used to allow the crank shaft to spin freely inside the engine block. The oil pump lubricates these bearings and they are designed to withstand the torque of the engine.
When main bearings fail, a distinct deep knock sound will be heard inside the engine. The engine will have to be rebuilt or replaced after a main bearing fails.
