creaking and other stuff going on....

I used to get this all the time on my old Ranchero. Just some wear and minor rust in some bushings...but it eventually revealed itself as wear on the upper bushings. Try spraying silicone lube (not WD40) on the upper and lower control arm bushings, and in the T-bar sockets on the back of the lower control arms. And then pump some grease into the upper and lower ball joints. (Oooops looks like you did already; good!) If you want to better ID it, then do it one spot at a time.

If either the upper or lower bushings stop squeaking with the silicone spray, then you may have a worn bushing that is moving where it should not, and that needs to be replaced. None of the stock type bushings actually rotate on anything; the rubber just twists. Such wear may easily not show up with the tests you did, but it is wearing things that should not be worn, and needs correcting.

ALSO....thoroughly visually inspect the crossmember front and back sides under the car where the T-Bars anchor, and all around the K-member; if you have a crack developing, then it can creak and groan like this.

Finally, for what it may be worth, the inner tire wear could be due to a number of things, and the ride height difference is not on the top of my list of suspects....misalignment is #1 and then misalignment caused by a worn part is #2.
