I've got a Lippert axle, and it has a plug and zerk fitting in the hub. However I've seen these setups in the past where that's just to 'top up' so you have to be very careful about blowing out past the seal.It seems to be fairly common now that the hubs are desiged to expel grease out around the nut and the zerk connects behind the rear bearing.. so you can just pump grease in (while turning wheel) and sorta replace the grease. Dexter has EZ-Lube, Lippert has Super Lube.As far as I know there's no sure way to tell from looking at the hub. Some of the rubber plugs will be branded Super Lube or the like however mine are plain. I sent off an email to Lippert to find out for sure.On the axle 'info' label, above serial number is a long series of letters and numbers, in my case:LCI35-SB-77.5-59.5-NOSP-US-L-545-729The L bolded above indicates super lube. So now I know that 'in theory' I should be able to pump in grease without worrying too much about the seal. As this is a lubrication subject there's probably a lot of controversy, please refrain from turning this into a discussion of the merits. My purpose was to just let others know this is how you can tell.

Good info, but even with the Super Lube, I would hand pack a new trailer.

They can name them whatever they want. It either has a grease fitting or not. It is just a hole drilled In the spindle that exits right in front of the seal. Good luck.

Good luck.Having a zerk fitting does not mean the grease is entering in front of the seal. I've had boat trailers and one popup that had a zerk in the spindle (NOT in a dust cap like a bearing buddy) and those both had the grease entering between the inner/outer bearings.. and no means to allow grease to exit through the outer bearing (both had a large washer that effectively blocked the exit). Those hubs are not the same as ez-lube/super lube hubs and that was what I was trying to determine by checking with Lippert.Use them as designed or not, don't care. Just trying to help others positively ID.

Good luck with keeping it on topic. You may want to include; diesel, Half ton, Chinese, Honda, and LT tires so that you attract all the naysayers. Besides, everybody knows that hand packing with long fiber cup grease fortified with Amsoil is the only safe way to travel.And you should make the dealer replace all axles supplied by Lippert, or anyone else.

Lippert axles-how to determine if you have a Super Lube hub

My TT is going on six years old. I do not know about the previous owner but I have put over 20,000 miles on it in the three years I have owned it. Until I decided to replace the brakes it was lubed though the EZ lube zerks once a year.

When I did pulled the drums the bearings were well lubed. I cleaned, hand packed, then EZ lubed them. I like the idea of having the axles shaft filled with grease.

I have been told you can over pack them but the manual said to spin when wheel and watch for grease at the front bearing while pumping. It worked for me.

Perry Mason used to say, "That is, Incompetent, irrelevant and immaterial". The rules of jurisprudence do not apply here and some folks search out any topic on which they can repeat their opinions that will never change. They look for any wormhole at all to join in the conversation. I think the weather has something to do with how much time we have to waste on here. It is 100 degrees here today.

I believe I have the same axles on my new Jayco as well as our previous KZ. I'd gently pump a little grease in and see if it starts pushing the old grease out through the bearing. I'd be willing to bet a Jimmy John's sandwich it will.:B

OK, Welcome to the forum and have fun. Opinions don't necessarily come from geniuses.

braindead, it looks like you are new to the forum here. Welcome to the discussion group.

You will find that when someone posts a subject, much like sitting around a real campfire in the campground, thoughts and insights from different folks will take the discussion in many different directions.

My reply to your original post was literally on the topic of the devices which you started the thread about. Other folks reading ( listening in ) may in fact want to hear "the rest of the story".

Here is a suggestion: if a person is going to post here, it's good to not be too thin skinned.

Again, we all welcome new members to the forum. So there you are "welcome new guy !"

Since this is a technical related subject, why not "discuss the merits" of it ?
Should we also discuss the merits of WD hitches, that's a technical subject related to trailers? How about the merits of Lippert products in general, or lubricating your chassis as the subject mentioned lube? Where do you draw the line?

I think the line is drawn with the subject as a whole, anything related to determining whether a Lippert axle has a super lube hub would be appropriate.

Once you start a thread... the conversation takes on a life of it's own... That's just the way public forums work. You cannot control it.

So long as it is civil.... And I am not talking about different points of view, but name calling etc... It is all fair game.
