Use a breaker bar correct socket hit braker bar in the right direction with a three pound hammer it shocks loose?

To loosen a stubborn bolt, first ensure you have the correct socket attached to a breaker bar. Position the breaker bar so that it is aligned in the direction to loosen the bolt—typically counterclockwise. Then, using a three-pound hammer, firmly strike the breaker bar to create a shock, which can help break the bolt free. This method leverages both torque and impact to aid in loosening the fastener.
