You do not need that balljoint press, a large deep well, piece of pipe and a hammer does wonders.
To remove hub. Undo the allen screws on cap. Remove cap
Take two small screw drivers, or the tool if there is one, to remove lock ring. Take a pair of snap ring pliars and remove snap ring. Take two of the allen screws and start in hub, remove hub using allen screws as a handle. Take the right socket to remove the big nut. Once the big nut is out you can remove the hub. I also remember there is like 8 more nuts you have to remove to get either the rotor or something else off, remove them to take what ever it is off, you will see it when you get to this point
To get the knuckle or what ever it called off, the thing with the ball joints in it. Get the biggest hammer you can possible wield and swing accurately. Beat the living snot out of the top balljiont until it falls off.
Once you got that off, take the snap ring off the bottom ball joint, secure in a vice and i do mean secure it in a vice, take a punch and that same hammer you had, and hit it. The ball joint will come out with a couple licks. Repeat for the bottom one. Now since the balljionts are now out take your new balljoints and find a piece of pipe or a socket that goes around the OUTER edge of the balljoint. Once this is acquired, tap the ball joint in. Do not use the hammer you used to remove them with. Install the new snap ring on the bottom ball joint. install knuckle
That is how i installed balljoints on my truck. I had to move up to a 15 pound sledge to get the passenger side knuckle off. It was awful.
