I've discovered that one of the dust caps that covers the bearings in my axle was lost on a recent trip. Are dust caps all the same size? Or does anyone know what I would need for a 2017 160RBT?
Thanks, Greg

Do you have the refillable bearing caps with the vinyl dust cap or are you talking about the regular metal dust caps? If it is the metal ones, they should all be the same size for your hub size.

Yah, I would think any cap meant for that size hub would work. I hope you can find them separately. I think you can. Maybe even Walmart.

Do I measure the diameter of the hub? And that's the size dust cap I search for?

To do that, you need to remove the hub to inspect the brakes and then the grease seal to remove, clean, inspect and pack the bearings with grease. If you want to pump grease in there you will need to keep pumping grease in till fresh grease comes out which is a mess and a needless waste and makes future service a chore. Often the grease pumpers push grease out thru the rear seal, destroying the brakes. That grease fitting is nothing more than a sales gimmick for the lazy or unknowing.

You can try here. They list a few with the insert: Or look on the axle for the model tag and manufacturer. Probably Dexter or Lippert. They may have replacement caps.

Howdy Wazkaren, When you do find a replacement bearing cap and get ready to install it, jack up that tire and check to ensure the wheel bearings are adjusted properly. Just grasp the tire 180 degrees apart and try to wiggle it. Should be mimimal "wiggle to it. There are some YouTube videos you can watch to help with the inspection process.
Sometimes, if the bearings are wearing or going out, it will cause the hub to move around in a manner that causes the dust cap to come off.

On the long trip I just completed a few months ago I found that the wheel hubs often came off., while travelling. When I found the type that fitted I bought some spares. I would check every 5 thousand miles and possibly grease then as well.

In my 25+ years of being a mechanic and working on trailers dust caps only come off when bearings aren't adjusted properly, the dust cap wasn't installed right to start with or curbing it. There is a the rare instance where a dust cap might come off on it own. As far as the EZ lube axles are concerned, they are junk. You will never get a good grease fill in the bearings. I take mine apart annually and get all the old grease out of the bearings (brake clean works good). I repack them by hand (I'm old school) using marine wheel bearing grease. I always install new double lip seals. I throw away the EZ lube caps and install standard grease caps. They make tools to install them correctly or you can make your own like I did with the correct size pipe. Make sure you get them seated fully.
