As most people with a 450/570 or older models (500,800 etc) know already. That stupid from pinion seal leaks sooner or later. Change them and they still leak. I’ve had mine all apart and cleaned and replaced all bearings and seals. Rode twice now and boom pinion seal leaking once again. It definitely doesn’t help that the driveshaft running to the front diff is 3 feet long with out any supports and meets the pinion at a weird angle.
So my question is... does anyone have a good fix for this?
