One ride last year we had an 08D8 break a steering posst off way back in the mtns. That was fun try to get it out of there. Had to tow it to steer it, but was too deep and soft to just tow it. So the owner of the sled had to sit on the dead sled and run the throttle to get it up the mtns we had to climb to get out. Of course it was comical watching him fall off repeatedly since there was nothing to hang on to other than the gas cap.... Long ride out that day.
REPLACE IT!!! The welded one might work as a spare to get through a day, but I would not trust it day in and day out.
