Dexter has the Nev-R-Lube bearings for all their leaf and Torflex axles. They don't have them for the 5 bolt x 4.5" wheels. I think the only other limitations are you can't use positive offset wheels, and only straight axles on the leaf springs. They come in three different sizes for axles from 3500# to 8000#.

Hi--The Nev-R-Lube bearings are a double row cartridge bearing made by Timken with a common bore and outside diameter for both roller assemblies, so they are not interchangeable on standard axles which have a large bore bearing inboard, and a smaller bore bearing outboard. IMO they really don't function any differently than the standard bearing set up we are familiar with, which has two bearing assemblies, and two seals. IMO the current two bearing set up would also be good for 100K miles if we didn't disassemble, and regrease it. IMO most all bearing problems are created after bearings are disassembled for regreasing: too much or too little grease, damaged seals, brake dust and contamination in lub, incorrect bearing adjustment. The last one is the big bearing killer. Wheel bearings MUST BE ADJUSTED LOOSE. Tighten nut until all play is removed. Rotate wheel to spread grease. Back off nut until loose (usually one cotter pin position), insert cotter pin, grab wheel top and bottom and shake. Should be looseness you can feel (1/8" to 3/16" of play). Take for a test drive. Feel hubs. Should not be hot on the back of your hand.--Frank S

Do you know how to tell if a Nev-r-lube bearing is bad? They can and do go bad, it just takes (usually) a long time before they do. Most people that DIY their wheel bearing repacks know what to look for in a non-sealed bearing.A bad sealed bearing may or may not have any play in it, and may or may not have a telltale leak of grease.

Hi--What I see happening with Nev-R-Lube bearings is that A/S owners will take them apart, to see if they are OK, damaging the seals in the process. When they try to purchase new seals they will find they are a size not commercially available, and will have to purchase new bearings. I did not get Nev-R-Lube bearings on the new Dexter Torflex axles I had mounted on my A/S earlier this month.--Frank S

Dexter recommends that the Nev-R-Lube bearings be inspected once a year, DURING routine brake inspection.

Yeah, like thats ever gonna happen.

I agree, more likely the whole process will get put off, then forgotten.

I do think that Henschen might take a fly at cartridge bearings, now that they are part of GKN. They build 200 million CVJ units each year.

If you seldom find a leaky grease seal but all too many times find grease on the shoes, where does the grease on the shoes come from?

Packing the bearings, with an excessive amount of grease, that all to many shops as well as owners do, will cause the grease to be forced out through the grease seal.



Grease seals also wear in time, allowing grease to seep through.

Grease seals should always be replaced when packing the bearings. However, some owners do reuse them, again and again, which promotes the problem.

Grease seals are very cheap when compared to the resulting costs when they fail.

You can prevent leakage past the grease seals with a very simple 'blow-out' fitting on your hubs.

Next time you order grease seals from Redneck Trailer Supply, also get a set of E-Z Lube hub caps, with rubber plugs. Don't get the hubs, just the press in caps to replace the solid steel caps.

If you accidently overfill the hub, it will first bulge out the rubber cap, then start to leak out the front so grease doesn't get on the brake linings.

Here's a picture.

You need to insist that the zerks were there, he must have busted them off!

Then, while he is bent over studying the situation, you tap him on the shoulder and he ends up with a nose full of old grease.

Don,

What is a CVJ unit - just curious?

A constant velocity joint - the prop shaft on any front wheel drive car. They make 42% of the drive shaft assemblies used in the world (their numbers). All of them use cartridge bearing assemblies.

Older Airstreams and Axles?

I'm new enough to the game to ask nussence questions. I have seen several references to axle replacement. Is this a common problem with older trailers? and how do you determin that one is bad or needs replaced?

Airstream used Henschen axles on your trailer.

The rubber rods used in the axles from 1974 and back, have a high failure rate.

The following article will help you to become an expert in checking out your axles yourself.

Now there is a can of worms - I'll give you my simple answer and let the rst chime in. On your AS, which should be a torsion axle - it's the angle of the torsion arm in relation to the frame. More acurately it's the down angle of the torsion arm to the perpendicular axle axis. It should be down - oh say, 25 degrees when original - over time the rubber insert weakens and relaxes and this angle goes to some smaller number and the axle no longer gives the bounce (or prevents bounce) like it sould - transfering the shock directly to the body and that starts to damage stuff.

There are ALOT of threads on this subject - use the search option above and type in "axle replacement" - you will find all you need.

I did mine a month ago - on a 66 Caravel - it was worth it.

a/s is still using dexters now (unfortunately) and since the switch in 05/06...

the other negative is they are now using dexter disc brakes on the factory side, while the factory service center uses kodiak, as does the dealer network...

i've been told the dexter brakes use pads not as widely available anyone know?

also, as i understood, the switch to dexter has to do with canadian certification...

dexter has full cert, while the long time j/c axle maker doesn't?...

so for less than 1% of the market we all get the the canadian spec'd part...

can anyone confirm this?

cheers

my 05 has henschens...yes!

2air,

To the best of my knowledge, there are only 3 manufacturers of axles in the USA that have CSA (Canadian) approval. Henschen is NOT one (unless they got it recently). CSA certification is quite a process. The folks in Canada are very specific about trailer axle requirements and performance standards, while the folks here in the USA have no certification process. The axle certification takes time, money and a big commitment by an axle manufacturer. With out the certification - the axle is not allowed on the Canadian roadways. Some RV manufacturers stock two types of axles, CSA approved and non-CSA approved, they simply install the CSA axle when required. The problem is that if the axles are mixed and end up on the wrong unit - Canada is a long way to go to change an axle. Thus 90+% of RV companies choose to stock only the CSA axle. In other words CSA certified axles are approved in the USA - but USA axles (with no certification) are NOT allowed in Canada. The CSA approved axle is the better of the two axles - as they have met the test requirements.

I too wonder if the Airstream recall (lack of grease) wasn't a factor in switching to Dexter.

Additionally, as an RV manufacturer (or any manufacturer for that matter), it is not the smartest move to single source a product such as an axle. When I worked at Jayco we had a single source for plastic parts - this was great until the vendor had a fire and almost shut us down for a month. That was a hard lesson and the last of the "we get these from this vendor only" days.

Also (last but not least) Airstream owned Henschen for a long time - until recently. Of course they would use Henschen when they owned the company but Henschen has sold twice recently - perhaps things have changed at Henschen convincing Airstream to look around a bit. In this looking process - I am sure that the Engineering team at Airstream selected the best (as they are so good at doing) alternative for the customer. The folks at Airstream have invested millions of dollars into R&D and would NOT use a Dexter axle if it were a "lesser" product.

Just several thoughts from a retired Axleman!

Best regards,
Henry
