I have a 2001 Dodge Ram 2500 4x4, with the cummins HO 6 speed manual. Truck has the Edge w/ Attitude box, along with after market intake and exhaust. After having the transfer case rebuilt, along with a new clutch installed (truck has 300,000 =/- miles), I was driving in 2WD, and at a shift point, felt a jerk and something break free. Pulled over and had broken a U-joint in my rear driveshaft. Rear driveshaft actually fell out. Being a 1/2 mile from home, and at 4am, I shifted the transfer case into 4x4, and rolled on. As I pulled into my drive I heard a terrible grinding noise that almost stopped the truck dead in it's tracks. Towed it back to the place that did the transfer case and clutch (within a month of each other, separate breakdowns), and they informed me that I had bearings out in my front differential which was causing my front drive shaft to jam the pinion up inside my diff. Not wanting to pay the $1200 expected rebuild costs, at least not to this particular vendor, I loaded it up and hauled it home. Had a mechanic tell me I could remove the axle shafts (?) from both front wheels, put it back together and drive it as 2WD and everything should be fine. I removed wheel, brakes, rotors, axle nut, wheel bearings on both sides, (destroyed a wheel bearing assembly in the process) and both axle shafts (I don't know whether it's called an axle shaft, half shaft, or what. Each individual unit with splines on both end, and 2 u-joints at wheel side). Purchased a GMB wheel bearing assembly (with speed sensor attached) from HubandBearingWarehouse. I then re-installed both wheel bearing assemblies (with no axle shafts/nut) rotors, brakes and wheel. Pulled out onto the road to test drive vehicle, and traveled literally a 1/4 mile, and as I slowed down to turn I felt it locking up. Stopped, put vehicle in 1st and slowly released clutch, but it was totally locked up and didn't want to move. Defintely something jammed somewhere. Put it in reverse, let out clutch slowly and it seemed to free up, and I was able to drive it back home in reverse. Still seems to be jammed when attempting to move forward. Shifter lever is in 2wd in shifter case, and 4x4 light is not lit. I get out of truck, walk around to the other side and notice that the new wheel bearing assembly has split and wheel is canted at an angle. Item #1-Anyone have any thoughts on my drive train jam issue? Item #2-What's thoughts on removing the front axle shafts and driving it as 2wd? (I know it defeats the purpose, but this particular truck is used as a backup utility truck when we're short a vehicle and rarely has to be off road) Item #3-In order for this to work, do I need to put an axle stub or something in behind the wheel bearing assembly to help hold it together?
