...with a 93 968 Tiptronic, I noticed driveline shunt on the overrun, after a day of fast driving.

I suspected the tranny, but my local erstwhile mechanic took one look, and pronounced 'doughnut' failure.

Pic of what came out, here: HERE

As you can see, there's nothing to weld...........

So, yep, when it goes, it well and truly goes. No damage though..........except to the wallet. My mech (and this was the first time he'd been under a Porsche) charged me Eur 900 for all work, and I supplied the doughnut.

Fwiw, my doughnut reached 145k miles and 15yrs old, so I don't subscribe to the every few years thing.

All my 0.02, as they say........
