There is no upper ball joint on this type of suspension. Basically, the upper part of the knuckle is held in place by the lower part of the strut assembly.
I attached the info below on how to replace the lower ball joint and a diagram that shows the details on the suspension.
Here are a couple of guides that will help with this, but your detail is below from the manual. Your lower ball joint is bolted in so you will not need to press them out.
Please run through this info and let us know what questions you find.
