So after trying to lubricate the U-joints multiple times I finally figured out that the squeak is coming from the rubber boot on the steering column. It's the first thing you see when you take off the panel in the footwell area. You can see it in this video.

I tried 3 different lubricants. Silicon spray, u-joint grease and dry graphite. But the squeak always comes back after a short time. Any suggestions? Maybe a piece of tape or something?
