What is a spun bearing? Can you drive on a spun bearing? You can have a spun rod bearing or a spun crank bearing and when they fail, it sometimes destroys the engine like in our Lemons BMW. In this video I show you how to diagnose a spun bearing and possible causes. We disassembled the entire engine, every single nut and bolt, so you guys can see what causes an engine to throw a connecting rod and fail.
