ball joints help

When I did my upper ball joints, I sprayed the threads in the a arm for a few days with penetrating oil. Then got a big pipe wrench and a torch and worked them loose. There is a socket that's special for this job and makes it so much easier. But I've only done two sets of ball joints and the pipe wren h worked both times. Lower ball joints are easy as cake though.
You have to take your wheel off, then take the caliper off, then the wheel bearing nut followed by the bearings and then the rotor. You will see the bolts that hold the Balljoint to the spindle. I'm sure you have the rest figured out. Don't forget to grease them after you install them. They aren't always sufficiently greased from the manufacturer if at all.
