Have the oil bath "maintainance free" vault system on my 2009 ez loader/ skeeter trailer. Rear seal was leaking so I pulled the hub off to see what was going on. At the time I did not know that these hubs can not be refiled. So after pulling it apart I changed the rear seal but there is now way to fully refill these hubs. I put as much 90w gear oil as I could in it then put the front seal back on. After reading I noticed that there is this "hybrid oil that is used in it and it is pressurized. Anyone ever had problems with there "vault"system? Any suggestions? Looks like I voided warranty by attempting to repair myself.
