The Install
Chock your tires snugly behind and in front of the tires to ensure your truck isn't going anywhere. With the chocks firmly in place, run your floor jack under the axle, behind the tire and the ball joint you need to repair, and properly seat it on the axle. Next, use your lug wrench to loosen the nuts. You want to do this before you lift the tire off of the ground. Otherwise, the wheel will spin when you try to loosen it. The easy and effective way to get your tire off is to loosen each lug in a criss-cross pattern, which prevents stripping or cross threading when you later replace the lugs.
With the lugs loosened, next jack the tire off the ground (an inch or two should be adequate), slide your jack stands under the frame of the truck and seat them in a durable and reliable portion of the frame. With the stands in place, slowly relieve pressure from the jack and guide the truck safely to the stands. You'll need the jack a little later, but we'll get to that.
Completely remove the tire lugs and dismount the tire. You should now see the ball joint, which is mounted in the A-frame. The joint itself will be connected to the steering knuckle, with two control arms that extend upward and are bolted to the frame. First, remove the ABS line from the A-frame. This step is important to do first. If the line gets crushed or pinched and looses integrity, you're looking at some serious problems.
