front cv axle outboard joints question

I have been having front cv axle woes. What I noticed on this latest round is that there is in & out (left to right, right to left) movement at the outboard joint. Well, this also causes inboard movement, however i am hearing it at the outboard.

To clarify, I am not referring to the whole axle. Dust covers & ends stay put. This is internal, at the joints. & under load. On all fours....

I have the beefier extended aftermarkets, which my truck seems to like (they feel solid), however I had leaking seals, so these have been uninstalled & reinstalled a number of times. Main problem with these axles is that there is not an inboard lip to tap to help when uninstalling, so resorting to pulling on them is almost unavoidable, which may have taken a toll on the joints.

I am going to have another go at it. Taking advantage of the lifetime warranty & install new ones. However, before I do so I wanted to make sure that the movement I am getting is not as it should be? Or maybe attributable to something else? I did the ecgs replacement. Anyway, I can feel it at the joint itself. Not at the hub. Also, would this movement cause leaking at the inboard seal?
