The rear could need new spider gears and a crossshaft and or that play could be from the ring & pinion.

Time to pull the cover and have a look.

You mean a new bushing where the yoke slips through or?

Sounds like no gear lube in there.

I'm not too worried about the trans output shaft flop when the yoke is removed. The output shaft is supported by the yoke. The tailshaft could likely use a bushing, maybe a new yoke depending on wear.

But that rear end? That's a clanky boi for sure. Pull the cover, lets see what horrors are hiding inside.
How many miles on this boat? For those of you that may have missed it, a Grand Safari is a station wagon.

Good to know about the shaft. There's no noises or vibrations during driving FYI. The car has a 122k miles and I don't know about the history concerning repairs or replacements. Only that it left California in 2006 to travel to the Netherlands! I will pull the rear end cover soon 👌

Tranny output is fine as it is supported by the YOKE and bushing in the tailshaft housing. That rear diff sounds EMPTY and or 1/2 million miles? That noise is the "clash" between the pinion gear and the ring gear indicating (judging from the amount of rotation) alot of backlash. If it doesn't make noise accelerating or decceratling it must just be MILAGE. If noisey in either direction you should look at pinion bearings.

As mentioned, the diff is full of oil. And only making this noise when shifting from and back to drive or reverse, nothing when accelerating or deccelerating. I will pop the diff lid later today and make another video 👌

My moneys on the spider gears and the crossshaft being worn.

If so hopefully the crosshaft bore hole in the case are not allowing rocking movement.
If so then you really got issues that only a new carrier will resolve.
