I've tried both tightening and loosening it while putting the appropriate pressure (up or down, depending) to try and get it out. Nothing will move it. The screw i put in is only a quarter of an inch longer, i don't understand the problem. But at any rate, it's stuck, so if i get under the car i should see where it is? Should there be a panel covering where its coming out? If it's coming out? Do they come out?
