Default Greasing Trailer Hub Without a Grease Fitting

Going on a short trip and want to grease up the hubs on a small trailer. There is no grease fitting under the rubber plug see pic below. What the best way to grease these up?

was there previously a fitting on the end of the spindle? if no grease fitting on the end of the spindle, possible it worked its way off and just need to press in a new one, or it was never an easy lube to start with. if there use to be one, simply press in a new fitting! if it was never an easy lube system from the start, id purchase a set of buddy bearings and go from there!

Have you poked your finger in there to confirm? It's often slightly off-center. And be careful bc the edges of those caps are sharp.

on a boat trailer, how often are you really going to remove and repack bearings? not that often, hell most folks wont even use the easy lube as often as they should!

The right way to do it is not the easy way, and it allows you to inspect the bearings. You pull off that metal cap which exposes the nut and cotter pin, which you remove. Then you pull that hub off the spindle, exposing the bearings. You take those off and repack them with grease, then put the bearings on the spindle again, put the hub on, and put as much grease in the hub as you can. If that's too much work, you can just pop off the cap and clean as much grease out of there as you can with a paper towel and then throw more in.

The bitch of it is, 95% or better of all axle greases on the market turn to liquid when heated from road travel and then the vehicle backs the trailer into the water and the liquid grease gets washed out. Why do you think there is so many axle/ bearing failures?

while i do agree, but i highly doubt anyone is going to remove and repack the bearings after every couple of trips! that is why you keep the grease flushed out with the easy lube!

the cause of axle bearing failure is due to the owner operator not knowing how to handle an axel that gets dunked in water!


i have been using this grease, when you try and wash your hands it gets stickier! and really repels the water. had to use the parts washer to get it off my hands! have not had any issues since using this grease!

Leave the rubber cap off and slowly pump new grease in (looks like red lithium) until you flush the
old stuff out into a trash bag under the hub. Clean the rubber cap off and reinstall. Some like
to use a bearing buddy bra over the cap just as an added later of protection from water intrusion.

Take the hub off, remove the old rear seal, remove and hand grease the bearings, put in the new seal and reassemble. That's the old school method.

My current and last trailer had them on the back. They are far superior to a front lubed hub or one with a bearing buddy. Little bit of a PITA to get behind the wheel but they are nice because in theory, you can force the old grease out the front of the hub as you pump the new in.

Put some of your grease, any grease on a table spoon and put it over a flame, if the grease melts and turns to a liquid then that is what it will do when you are motoring down the highway. And if the grease is still in a liquid state when you back the trailer into the water your grease is being washed away.

This is true. I replaced axles on a trailer with this type. It makes total sense, the grease works from the inner bearing towards the cap.

correct! no one is questioning the grease heating and water entering the hubs, that is why you keep them flushed with grease!

also your lighter test is not really showing anything! being a lighter burns about 1200-1400c, if your bearing are getting that hot to melt your grease, you have a bigger problem than just the type of grease!

I thought the easy lube hub/axles with front fitting did the same thing. Forces grease through the spindle to the rear bearing and then out through the front bearing.

Correct, just in a slightly different way. The OP's spindles don't have a hole drilled through the center. The grease is forced over and through the bearings and out the front in a one-way path. The drilled spindles have to get the grease behind the rear bearings in a steady stream so it flows forward through both sets.

One of my trailers has the spindle passage and gets lubed from the fitting on the end.

Another has the hub fitting.

If an axle has no passage and end fitting a hub with a fitting can be installed.

Both of these are superior to "bearing buddy" style solutions because those do not force the old grease out.
