I had to use a breaker bar. Sprayed WD40 on it and let it sit for a half an hour. Then used the wrench and a breaker bar (2ft long, careful not to buy too long of a pipe, or youll have no leverage due to the end hitting the ground). I actually ended up using the handle for my jack, I cut off the rubber end and it fit right over the wrench. Just make sure you are using the right size socket so it does not strip.
