I've been talking up the 10 bolt and D44 for years saying that I've never seen one break with a stock small block. Up til now, that was true. Well guys, I was definitely wrong. I mud bogged yesterday and today both. Yesterday it wasn't competition, I just helped test the pit to see if they had to fix it. Today, I bogged for real. I made it all the way through yesterday and a couple other guys did too (but at least 70% got stuck yesterday). Today, I made it all the way to the end of the pit and my truck stopped about 10' from the end. They red flagged me to stop, but I stayed on it anyway. I threw it in reverse a couple times trying to get through those last 10'. I wasn't even really beating on my truck that hard (although I was in 4 low, 2nd gear, and holding the throttle on the floorboard) and my right front axle u joint let loose, taking the stub shaft with it. The crowd loved it. At the end I think they really wanted me to make it, they were cheering for me and then I heard about 1,000 people sigh at one time when the axle u joint let loose. I really don't give a rats anyway, I've got a spare set of shafts complete and a bunch of extra stub shafts, I just am really shocked that I finally broke it. Oh well...I'm only gonna fix it this once, (and only because I can do it for free) then it's '60 time!
