I have a 2008 bighorn with the hemi and at 49k miles the rear is starting to rumble although it could be an axle bearing that could be going.
Per the paper work on the truck it isn't clear if it has posi-traction but I doubt that it does but it does have the tow package. The rumble is at all speeds and doesn't change pitch or intensity with speed changes. The truck has never been overloaded but I'm ready to start towing a trailer with a GVWR of 6000 lbs and I'm concerned. Has Dodge had trouble with axle bearings?
