Ball Joints or Wheel Hub

Has anyone done these changes on their JK? I'm trying to figure out if they're easy DIY material, suitable for a wrenching party, or best left to the pros. Any input would be appreciated!

I have done the upper ball joints, and they can be kind of a pain, you want to make sure you have a good ball joint press, I rented the free one from AutoZone and while it worked it wasn't a perfect fit for the JK ball joints. Its not overly difficult but its time consuming...
