Busted the front differential in my 2012 900 trying to back out of a hole, really wasn't on the throttle much. Been looking for a more heavy duty front end but haven't found anything other than stock. It busted wear the pinion bearing seats, I ordered a new diff , trying to figure out if I could make it stronger in that bearing section, it's kind off thin. Welding on it would more than likely warp or weaken it, thought about getting a piece of schedule 80 pipe that would fit around it and pack quicksteel between the pipe and bearing housing. Not sure if this would help or not, anybody have any suggestions.
