Help with Engine knock noise at shutdown

Hi guys new to the forum and just getting back into the jeep world. I picked up a 92 Cherokee 6cyl auto with around 170k on her. Now after daily driving it for a few months I have noticed a new noise development. Randomly at engine shutdown I can hear a clear pronounced single knock right as the motor seems to stop rotation. The strange thing is that it happens about once in 10 shutdowns. I have decided all the usual tune up stuff since I got her. Searched Google for anyone with similar posts but could not find anything close to my symptoms. Any ideas would be a help.

Thanks Eric.

My old zj did this, I wasn't 100% but I think it was the metal collapsing because it expands when hot

Make sure its not loose and rattling transfer case lever. Could be mistaken with engine noise.

Ever inspected your engine and trans mounts?

The kid I bought it from said that he had replaced them. I remember noticing that the trans mount looked new when I was doing some tcase work on her but I will take a closer look at the engine mounts next time I'm in their.
