So i went on a trail ride yesterday and its easy enough that a stock YJ can do so i was having no issues and definitely wasn't pushing the jeep. When we came to a clearing to stop for a break I clutched into neutral, rolled to a stop, then tried to put it in gear to park it. But it wouldn't go into any gear with the engine running even though I'd been shifting all day. The clutch doesn't seem to be releasing because with the clutch fully depressed it still tries to roll forward. No fluid is dripping anywhere so that doesn't scream master/slave cylinder, and the rod that pushes the master is definitely actuating. Also it developed a new sound where when clutched in I can hear a scraping noise in sync with the engine, almost like something is between the clutch and the fly wheel. Any ideas what it could be while I sit here and wait for a roll back?

It was lots of fun limping off of the trail in 4lo and 2nd and driving 18mi down a mountain in a 55 going 35 and stuck and 3rd. Almost as fun as trying to start moving in 3rd :facepalm:

did you do any mud, that could be dried to the clutch surface etc either this trip or the last?

Not likely. There were some soupy puddles but they weren't deep enough to cover my tire and I only went a few MPH through them since I hate cleaning. Also I was careful to not clutch in while going through the muddy water.

My first thoughts while reading your post were that your clutch master/slave cylinders could be leaking internally and therefor not working as well as they used to, that is a possibility. But, considering the new noise that you mentioned, and when you hear the new noise, other items to consider could be the throw out bearing going out or some type of mechanical failure inside the pressure plate itself.
