“With the naked eye and with the wheels mounted, it wasn’t visible… it can be seen on the brakes that they move up and down.”
Rear wheels try to move further apart from each other while driving forward

Axle shafts are bent and they need straightened or replaced.
I would find a shop that can do it, if you don't have the tools to do it.
Just to be sure… are both drive shafts the same? So I know what to look for if I want to buy new ones. I looked at some numbers, but they’re really hard to read. Or is it enough to just look at the Dana 44
Yes, and I realize you may not fully understand this but all axleshafts of that style are bent after they are heat treated. The flange wobbles and is not concentric to the splines. The manufacturer puts them on a straightening machine and bends them so that the flange runs true and is concentric to the splines. That doesn't mean the shaft is straight, is just means the splines run true to the flange and it doesn't wobble.
We call them axle shafts. The drive shafts are what connects the transfer case to the pinion yokes at the axle housing that the axle shafts fit into.
TJ Dana 44 rear axle shafts are about 1/2" difference in length with the longer and shorter sides matching the front axle. Short side on the left, long side on the right. The Dana 35 is opposite.
"TJ Dana 44 rear axle shafts" should be the search criteria.

Yes, but only because there are a few TJ Unlimited rear axles with drum brakes and you need disc brake retainers. The shafts are the same, they just have flat retainers for drum brakes and lipped retainers for discs.
Agreed it is likely the axle shafts. Only other thing I could see is if the rotors are really badly warped and aren't entirely flush with the hub, but I would think that the clamping force provided by the lug nuts would force it flat when the wheel is installed.
If you aren't too tight on funds, consider going with chromoly shafts. Those are stronger and less likely to fail. That said, OEM replacement shafts will work in many cases except for extreme abuse.
Note you specifically want 30 spline unless the previous owner put in something different (highly unlikely).

The video with the rotors removed clearly shows the axle flanges wobbling.
Can such shafts be searched by part number? Do you know what numbers they might have? The numbers that are stamped are unreadable. Disc brakes, without ABS. I would be very grateful.”
The car will be driven mostly on the road and gravel roads, no heavy off-road use
Possibly, but there are so many sellers in the U.S. that we never look for them that way. I find part numbers as follows-
Dana Spicer 84377-1 at 29.94" long
Dana Spicer 84377-2 at 29.21" long
I believe you, it’s just that there are very few TJs here in Slovakia, and my LJ is probably the only one.”
