    I'm about to be making a 6hr pull one way with the boat in a few weeks and I am trying to get all my maintenance done prior to this trip. My 09 trailer came with Vault hubs installed....which I am assuming are 7yrs old. I've read that every 5 to 7yrs these hubs need to be serviced, which I assume just means pop them off, check the bearings/seals and add some fluid. Has anyone ever serviced a set or owned a set? I know it requires a special hybrid oil blend. I'd rather not screw something up and get in the middle of Mexico and be stranded for someone to turn me into carne asada.

    Thanks

    I believe you only need to change the fluid. On another note you had better bring a back up hub. When the oil bath hubs go bad it's quick and severe! Like no warning until you see smoke. You might also bring a spindle/axle and the proper tools to replace it with. I had this happen just going to LBJ with my old boat which is about 30 minutes from my house with nothing over 65 mph. My trailer was only a couple of years old when it happened.

    LOL......I'll go ahead and bring a spindle, axle and drag my welder along too :)

    After some more digging, it seems it's pretty straight forward. They are designed to be maintenance free for 5yrs unless you purchased the $50 10yr plan at time of purchase. Basically it looks like to service them you need to check for leaks and then check for bearing play. I don't have any leaks so I am good there. If play is discovered they are "supposed to be sent in" to be re-torqued to factory specs".....but I can do that one my own. Outside of that it looks like you need a 1/4 ntp grease fitting and you flush the old grease blend out, and then fill per spec (using the proper grease) and install a new cap using lock-tite or permatex to seal.

    Sounds pretty basic so I'm just going to do it myself.

    I always carried a backup hub. Dont have one for this boat yet, but it makes things so much faster to replace should bearings or something fail while in transit.

    Yep I just ordered a spare hub, bearings and seals for the "just in case" need arises.
