Dexter Nev-R-Lube™ or Dexter EZ Lube axles

The title says it all. I am replacing my 4200 lb Dexter axles with 6K axles with the 3.5" heavy wall tube (custom order) I have a choice of hubs Nev-R-Lube or the standard EZ-Lube like I have now.



Anyone have first hand experience with the Nev-R-Lube?


I have attached a picture on the existing 3" tube that bent - the reason to go to a heavier tube. I will be getting the never adjust brakes like I have now only the next size bigger. The bend occurred on my Alaska trip. The other axle is bent too, but not as bad.


BTW I am aware of the Airstream recall involving the washer replacements.

I am a retired professional mechanic. Wanted to give my thoughts on the Nev-R-Lube bearing set. I have not used Dexter's Nev-R-Lube, but many vehicles use the same type of opposing taper roller bearings with cones in a single sleeve. I have worked on 100's of them. They are packed with grease, sealed and not serviceable.

I like the EZ-Lube system better. With EZ-Lube the bearings are serviceable and spaced further apart in the hub. Inherently stronger than the closely spaced Nev-R-Lube bearings, due to spacing. EZ-Lube allows you to grease the bearings which flushes old grease and moisture out replaced by fresh, dry grease. Can't do anything with Nev-R-Lube short of replacement which is more complicated than EZ-Lube.

If you ever encounter bearing trouble on the road, EZ-Lube will be far easier to get parts for.

My opinions. Others may chime in with their experience.

I had the never-lube bearings on my previous rig and I loved them. You still need to check them yearly for end play and you can do that by pulling and pushing on the top and bottom of the tire to see if you can feel any movement.


I also carried a spare hub with the bearing in case one did go bad. It takes a pretty good press to get the bearing out of the hub so I carried a spare just in case.

The current rig had Nev-R-Lube and had two with EZ-Lube. My preference is for the EZ-Lube since you can pull it down and maintain the bearings and get an idea of the life left in them. The Nev-R-Lube is a sealed bearing and you run it until failure. You are supposed to check them for play periodically. So far, we have towed the current rig about 40,000 miles in 9 years and I had one running hot out of the 6 wheels that I replaced about 5 years ago. This winter I am getting all of the bearings replaced.

Dexter states to clean, inspect, re-grease(hand-pack) their EZ lube bearing every 12,000 miles or 12 months, whichever comes first.
I had them on our last 5er, I never used the zerk fittings due to the Dexter requirement. It would have been a waste of time and effort to add grease to bearings that required removal @ 12,000 miles anyway.

Have Dexter Nev-R-Lube bearings on my 2007 5th wheel
7 yrs FT traveling weekly and another 7 yrs seasonal.

Same type of bearing on thousands of vehicles.
Check for end play once a year and go.

Personally I regard them as a step up from 'trailer bearings'

It boils down to whether you believe the "never" part of not. If you are skeptical, then you want the EZ Lube so you can maintain them. If you are trusting - or maybe just avoiding maintenance - then the Nev-R-Lube is your cup of tea.

The problem with the Nev-R-Lube stems from some cheap Chinese bearings. It seems that you will do a lot better if you can get a US, German or Japanese manufactured bearing.

Thanks Folks
As I have the 6 on 5.5 hub bolt pattern I am stuck withe 42MM cartage and the only manufacturer is Timken. Unfortunately this particular bearing is China made. I don't know of any other manufacturers of the cartridge, but if someone knows pleas let me know.


I appreciate the responses
Thanks

One other issue is you cannot run any off-set hubs with these bearings. This was what caused a lot of the problems early on.


I ran my set for 10 years with no problems. Not a high mileage rig but 2-3 thousand miles a year.

That is what I hear when I called customer support years ago. Hand pack every year.

I would go to never lube if order an axle.

Going from a #4200 to a 6000 axle I think the wheels change from 5 to 6 holes??

If I was ordering a axle I would get self adjusting brakes. Also torsion springs give you a much better ride.

Not a problem as I already have zero offset wheels.
