Dual axle trailer, EZ Loader, not sure of model as I sit here but I think 3500 lb axles. I have one hub that continues to let a bit of saltwater in, just enough to turn the stuff milky. Have tried three new seals, new o-ring on the cap, new cap. Still the same. I'm told the stainless sleve on the spindle can get scared and you won't get a good seal. Makes sense to me. Have heard two different pieces of advice. The guys at Six Robbles recommend just packing that same hub with grease. Have been also told that it is not advisable to go that route.
I'm tired of trailer hubs.
