This seems to be happening to lots of folks and on at least one Highlifter (’18) that I know of. Polaris replaced the hubs on one of my friend’s machine but the new ones leak as well. So I don’t know if Polaris will ever really fix this issue, although I would jump at the chance to get replacements from them that did not leak. Does anyone out there have a good solution?
I have a 2017 1000 XP Trail and Rock Edition. I and some of my friends have problems with the hubs in the AWD (AKA Demand Drive, front differential) leaking through the center of the hubs. I took mine all apart and attempted a shade-tree mechanic solution but it failed after a few days on the trails and rocks. Here is a link to what I did: Leaky Demand DriveUtah RZR Rentals
