I suggest you hold the coupler tight w/pliers and and try to spin the driveshaft while doing so with another pair of pliers or vise grips.

I have seen this issue before an 882 diesel which are hard on pins.
Both ends still in the coupler but the hydro input shaft not turning.
And when driving the old pin out, what's left of it comes out in pieces.
It may be tough lining up the coupler with the hole in the driveshaft when installing a new spirol pin, use a short length of 1/4" bolt shank to line the holes up and drive the new pin in while pushing the piece of bolt out the other side.

Good luck!

NOTE TO SELF: replace the pins in the 882 BEFORE heading to Bluneirs plow day in October!!

I did that and they seemed fine, so I took it back out and ran it without the cover and didn't notice it slipping any, but I did notice it whines a bit more in reverse than it does forward. It also didn't act up at all this time.

Is it just me, or do things always work fine whenever you're trying to diagnose a problem?
