Front suspension woes

Here is a tool I made per FSM to pop upper and lower ball joints free from steering knuckle. Remove castle nut of joint needing replacement, flip it over and re install flush with end of treaded ball joint stud. Place tool in line with and between booth upper and lower nuts and expand tool with two wrenches until it will no longer turn, then smack knuckle eye with hammer where tapered stud is held. It should pop apart
