Hey, I once had the same problem with a suzuki samurai i bought, I luckily have air tools and stuff, but what you can do, is take a socket that is half-inch drive(prolly only ones that will have the right size socket cuz 3/8ths are smaller) and hammer it on with a metal mallet or sledge, then take a 1/2 inch breaker bar and take it off, dont try a small ratchet because it will be hard to get off, U NEED LEVERAGE...
