Re: New ball joints
If your upper ball joints are bolted in, they have been replaced since they were riveted from the factory. If you are going to take it all apart for cleaning, the frst step is to loosen (don't remove) the castle nuts that are on the ball joints until there is about half the castle nut engaged on the threads of the ball joints. Smack the top and bottom of the spindle knuckle with a BFH until the top and bottom ball joints break free from the spindle. They will pop apart with alot of energy, so be ready for that. Once the top and bottom are popped loose, remove the shock and get a spring compressor on the spring and get the pressure off of it. After that you can remove the castle nuts and take the spindle off. After that, remove the long bolts through the bushings in the lower control arm, and take it off. In the upper control arm, remove the two nuts that you talked about that face the engine and remove the upper control arm. To get the bushings out, you've have to remove the 2 bolts that have the large formed washer on them that go into either end of the rod that goes through the bushings. These will need pressed out, so pay attention to how that goes because you will have to have the rod in the control arm as you press the new bushings in. It's not a terrible job, but be careful of the spring. There's alot of force stored in that spring.
Experience...... It's what you get when you didn't get what you wanted.
