Left is upper it slides a little vertically which is normal and right side is lower which should only rotate ball but no horizontal or vertical movement. Reason why I'm uploading this is a very well recognized 4x4 shop reccomend me to replace the upper one because they saw movement when they pried with a pry bar. The horizontal movement was normal due to spindle flexing lke 1-2 mm and thus the upper ball joint sliding up and down and replaced ball joint wasting time and money.
