Most of these trucks the lower ball joints press into the control arms, while the uppers are part of the upper control arm assembly and are not serviced separately. You would need a ball joint press to replace the lowers, and they are staked in so sometimes they are a bit difficult to remove. I usually remove the knuckle, bearing/hub assembly and driveshaft, and leave the lower control arm on the truck and use a ball joint press. If you are going to use a large vise to get the ball joint out you would probably have to remove the lower arm as well. An alignment is always a good idea after replacing ball joints.
