    I've got a 2003 2500 Ram 4X4 with the cummins.. I noticed yesterday that when locked in 4X4 and on the gas, a grinding noise was coming from the front end, sounded and felt to me like it was under the drivers seat or atleast in that area.. It only does it in 4x4 and under acceleration. All the U-joints are fine all fluids are fine. It was really loud and bad yesterday, and today wasn't as bad. Would the cold weather have something to do with it? It really sounds like its a bad u-joint, but like I said they all checked out ok. Anyone have any suggestions? The truck has 104,000 miles on it.

    Push button or floor shift t case? If it floor shift what the pattern of the shifter front to back? You were not on hard dry roads where ya?

    1 it could have been that you had not had it 4x for while and some parts where dry
    2 cretin transfer cases are set up to slip when the axles pull at different speeds ( this is mostly on full time t cases)
    3 Linkage not adjusted correctly between 2 gears.
    4 low on gear oil

    check your front tires, they might be worn unevenly, so that slight diffence means one tire turning faster( or slower) than the other, forces acting against each other, meaning grinding,humming, odd not normal sounds.....

    wheel bearings...etc,
