My 05 800 sportsman rear differential is shot. Cant seem to find much info about it as far as rebuilds etc. a new one is about 1300 which is ridiculous. A used one from Ebay is + - 300 but i dont know what Im getting. Is there any info out there on what year and models have the same diff as mine because i can get a 2012 800 parts bike 2 hours away the diffs look the same but now sure havent seen in person. Any other online parts places to find a rear diff?
