You can jack the car up and (support it safely) use a 24mm? box wrench on the nut. Use a 3lb dead blow hammer to help break it loose. It won't hurt to soak it with PB as long as you can either. You will get better access to the bolt by dropping the front subframe part as mentioned. Use a floor jack under the front to keep it from dropping too far. Once you get going you will see how it all works. Also when I'm under my car I like to stack a couple of tires under the corners just in case, even tho it is on jack stands etc. I just fell better when I'm beating on and pulling on wrenches underneath something. Good Luck.
