Jack the truck clear of the ground and let the wheel assembly hang. After you remove the tire place your jack under the lower control arm so it's firm. Remove the cotter pin, if you have one and loosen the big nut almost off. Wedge a "pickle fork" between the control arm and the spindle and give it a belt with a hammer until the ball joint pops. Raise the jack so you can undo the nut easily and separate the control arm and spindle.
The upper ball joint is riveted or bolted in. Grind the rivets or use a cold chisel and remove the ball joint. Clean up the area with some sandpaper, dirt , loose rust, etc.and put the new joint in. Put the spindle back on using the jack if necessary and put the nut back on and tighten.
The lower ball joint is pressed in. Tie the spindle out of the way and brace the lower control arm with some blocks or the jack if you have to. A few whacks with a hammer should pop the joint out. Clean the hole out lightly, just to remove loose rust and dirt. Put the ball joint, minus the grease fitting ,,in the hole and use the jack with a block of wood, to put it in place.You may have to fiddle with the spindle to make sure it is lined up. I've never had any trouble using a 1ton trolley jack and the weight of the truck to put the lower ball joint back in. Replace the nut and grease fitting.
The new ball joints will probably come with cotter pins, use them. Make sure the new joints are tight or they will wear the holes in the spindle. Don't forget to grease the new joints. Hope this helps.
