like some of you know, i had the jeep in the shop just 2 weeks ago to get a faulty crankshaft seal fixed. after the last time out at spring creek, i heard a rattling noise whenever i wasn't on the clutch...when i touch it a bit it goes away. So i went to the shop and they told me it's most likely the throw-out bearing. I'm guessing it happened when i was stuck in the clay hole. Shifting & pressing the clutch most likely sucked in some mud. If it is the bearing; it's covered under warranty, i just hope there isn't a bunch of mud in there...
