Bearing zircs

I have a 2016 339flqs, when we were camping last week I pulled the little cover off of the center of the wheel. There was a little rubber cap and when I pulled that out, there sat the grease zirc fitting...just like a bearing buddy. My question is how often should they be greased. I looked through all of my materials and could find anything...heck I didn't even know I had them on my wheels! Any help would be appreciated.

It's probably a Dexter E-Z Lube. The idea is to get the tire off the ground and spin the wheel by hand and S-L-O-W-L-Y pump grease in. The old grease will be pushed out the front of the metal cap and you get a re-lubed set of bearings without tearing things apart.
They get mixed reviews and folks seem to either hate or love them. The most common problem/complaint seems to be grease is forced past the rear seal (which contaminates the brakes).
I've got 'em and used 'em to lube the bearings which means I'm running on blind faith that the grease is getting where it's supposed to. I will eventually take it all apart and do it by hand just so I'll know it's done right.

I've had similar on boat trailers, of course they go in the water so greased them pretty regularly, so how often do you grease these?

You can go to Dexter's web site and print off the manual/info. You didn't get a Dexter book in with all the other manuals? BUT- you might be better off by removing the wheels and packing the bearings by hand. If you use the fittings and use too much grease or don't do it correctly you could blow the grease seal out and possibly have lots of problems with your brakes by getting grease on the shoes/drums. Sometimes the "old" way is still the best way.

Don't think they are Dexters...the little rubber cap say Lippert Corp. on it. Could they be a Lippert product?

Could be Lippert. They seem to have their name on everything now!

Remember, you can't patent an idea, so there can be other manufacturers could build and easy-to-regrease system.


I've got the EZ-Lube (R) system and love it for making sure there is always clean lubricant in place.


Having a zerk fitting does NOT eliminate routine dismantling of the hubs, cleaning, inspecting for wear and replacing worn out components!

I agree....manual greasing by disassembly is required....my question is how often to disassemble and how often to use the grease zirc method?

Every other 800 mile trip gets fresh grease.

Annual disassembly, clean, etc.

Works for my habits. YMMV
