you will need to jack up on the brake backing plate. that will put the weight on the jack. now use another jack or jack stand under the a frame. and one under the truck frame. the jack or stand that's under the lower a frame need to be about an 1" or 2" lower than the a frame, when you hit the lower ball joint with a big hammer the ball joint will drive down the lower a frame and the spring will push the lower a frame down, most of the time you will have to hit it several times...make sure you have a jack or jack stand under the lower a frame but not touching it.the spring will help you to get it out, and its going to be loud when it comes loose....or go buy a lower ball joint puller that fits your truck...
