Learned this from a previous thread. I found a broken front hub on my 09 S when changing the front bearings. One member mentioned the front hub and bearing upgrade for 2008 and 2009 800’s which I had never heard of. Found the kit on EBay for $135 which included 2 new front hubs part number 513729 and 2 new front bearings part number 3514699. As can be seen there is a big difference between the 2009 hub and the newer version.
