So I'm coming into my neighborhood and the truck doesn't feel right, I go to turn onto my street and clunk. The drive shaft dropped down and the rear end locked up, causing me to drift around the corner (kinda cool in an uncool way). Before I knew the rear end was locked up, one of my neighbors was kind enough to help get the shaft back into place, so we could at least roll it down to my house. Got it back in, cranked it over and popped it in N, no cigar. My son and neighbor pushed the truck but it swayed forward and came right back (didn't move) as if the parking brake was on or something-it wasn't. So there my truck sat, at the corner of my street with the hazards on waiting for the tow truck. I looked up the road I turned off of and you could see oil dripping all down the street and there was a big puddle of oil under the dropped shaft. Unfortunately, I didn't think to take pics until after it was back up :doh: I believe the rear end locked up and the force of the drive shaft not being able to move popped it out, and I assume the transmission is screwed too...any ideas what could cause it to lock up? It was towed to the dealer but I imagine I won't hear anything until Monday. The truck is an 09 Sport Crew 2WD Hemi w/ 42k. It was about to go in for an oil change...I guess we'll get it all in one shot. Not too worried thanks to the powertrain warranty, but still curious to see what it could be. Thanks guys, will post results when I hear more.
