me and a buddy were driving down a back road. he has an 03 common rail 5 speed cummins, yep an nv4500 they made a few. I have my signature truck an 01 lb7 6 speed manual. we pulled over next to each other and rolled down the windows. I looked at him and said two wheel drive or four wheel drive. he said "well four wheel of course". famous last words. we both locked them in and staged them up. I revved mine up to 3400 and dumped it in second, I heard a extremely loud pop. 
I was like shit I broke something. to my surprise everything felt fine and it kept on pulling fine, about that time I looked in my side view and seen my buddy already out of his truck under the front end. I turned around and popped under there to see what the deal was. he had all brand new u joints, he ripped to stubs off the u joint and it spun and broke an ear off the drive shaft yoke. I couldn't help but say it was ironic that my weak ifs with 240,000 miles was fine while his cummins with half the miles snapped a front end part. his being leveled didn't help im sure. we got it towed and removed the shaft and hes still driving it around. I couldn't help but post this. duramax 1 cummins 0
