keep looking...

Not all axles have H after the part number. Look at the 2002 trailers.

Dexters on Internationals

Classics do have Henschens. My 2003 does and there were big racks of Hnschens at the factory when I was there.

My 2003 International AS had a Dexter axle. The shipping tag from Dexter was still taped to the axle. I pulled it off and still have it in my workshop somewhere.

I have had two previous trailers with Dexter axles. As far as I can see, the quality and performance matches Henschen all the way.

What about another possibility DH keeps on considering. Our 61 is a from a transitional year. Most did not have duratorque axles. So, what about just reverting it back to a leaf axle?

You are correct indeed, Herb. It seems they were selective in where they were used, through 2004 apparently.

John,

I'm guessing your International had the Dexter Torflex axle? The Torflex, at least outwardly, seems very similar to the Duratorque. Why then, do you suppose that Airstream cheerfully uses Duratorques in triple axle configurations, where Dexter doesn't seem to want to? In reading up on their site they seem to make quite a lot out of not overloading the axles - even by doing something as relatively tame as going over a speed bump in a parking lot, or railroad crossing. I could see something like running off a big curb or hitting a large pothole, but the other examples they offer seem kind of ordinary.

Our previous trailer (large pop-up) also had a Dexter Torflex axle.

I just put a Dexter Tor-flex under my fiberglass Burro 17' last summer. It is the #10 3500 lb variety. It required that the old mounting brackets be cut off and new ones installed. The quality was excellent. It was $290 with brakes delivered to Midwest Wheel in Cedar Rapids IA. Talking with Jim Fogdall at Ace Fogdall in Cedar Falls IA, there is no problem with replacing the Henschen with Dexter, provided that the bracketing is done properly. I have recently relocated my '70 Safari, and believe it will need a new axle as well. I'll have no problem replacing the Henschen under it with a new Dexter when the time comes. If I do, it'll be with the Nev-r-lube bearing cartridges. As far as the Behemoth... I agree with Dave's assessment... although I don't understand why Dexter wouldn't recommend them in a triple axle configuration either... who knows... maybe Henschen doesn't recommend it either!

Well if Henschen didn't recommend it I can't imagine either Henschen or Airstream exposing themselves to such a liability. You don't hear anything about high failure rates with triple axle trailers equipped with Henschen axles... or any other axle for that matter.

I wonder what the big 5er SOB's with triple axles are running? All leaf spring? When Dexter's Torflex is available in capacities of up to 10,000 pounds?

Something doesn't jibe here, I'm thinking.... I can't imagine a difference of, at most, 500-700# of curb weight between double and triple axle trailers going over a railroad track or a speed bump being such a big deal.


Ah well.... whatreyagonnado......

I was thinking of the other kind of "allignment"..."toe in/tow out/camber/caster". they bend the axle tube for this. but they do it "just so".... I think they show this process in the axle plant tour on Andy's site.

And this may be the big selling point for the Henshen: they're a "bolt-on" item. (in most cases, anyway). And speaking of that, why hasn't Andy come in to this thread to show us the error of our ways, for even thinking about a "brand x" axle? LOL! (before you get bent out of shape...I'm just teasing!). Seriously, though, that is certainly worth something. but is it worth twice the price of a dexter? again, I say, "hmmm...."

I would think that the parallel/perpendicular thing should be "fixed" by the axle mounting plate. there's a square cut out that is the same size as the axle tube...that's where it goes.

Chuck,

I think the other alignment specs are either set by the manufacturer, or don't really matter in a non-driven/non-steer axle. The only things you can screw up when installing a new axle are the parallel/perpendicular measurements.

As for the 'bolt-on' feature of the Henschen axle, and the "fixed" axle cut-out, I think that's a poor approach. My frame was 1/2" out of line, I wouldn't assume that another frame is perfectly aligned and you can just bolt-on a replacement?

I would rather start from scratch, and make sure that the new axle, regardless of who made it, is installed properly, perpendicular and parallel.

Here's where I got the alignment info: http://www.goodyear.com/truck/pdf/ra...tread_S6_V.pdf
(skip to the bottom, page 7, for trailer settings)

but yours is a pre-duratorque setup, is it not?

Its in the airstream service manual...which I don't have handy at the moment. I'll look it up when I get home.

Airstream thought it was important to put a bend in these axle tubes....and I remember seeing at least one newbie post "yikes! the axles on my new-old trailer are bent "...and I thought the same thing when I first noticed it, myself. But the axle tube is much closer to the belly pan in the middle of the trailer than it is on the outside, near the mounting plates, forming an arc.

I'm not an engineer...nor do I play one on tv...so I can't comment on the quality of the approach that the A/S engineers of old took IRT the axle mounting plate, etc. but it is the way it is. It would seem to me that if the frame were that "racked" out of square, it would take a whole lot of metal work to fix it. (how/what do you measure to determine this, anyway? )

Chuck,

You're right, my frame is a 'pre-Duratorque', but it was still racked by half an inch. I don't know if they do a better job of alignment now than they did back then, I sure hope so. (although from reading some of the Quality threads, I'm not sure.)

The Dexter axle I put on had the regular bend in the middle to set the camber. I don't know if the Torq-flex axles have the same camber, but I assume they do, just like the Henschen axles.

As far as how you check if the trailer is 'racked', it's pretty easy with a tape measure. You just measure from the center of the coupler to the end of the axle. If both sides are equal, you're good to go, right? If they're not the same, you need to move one side to make it so. In my situation, we were putting on a new coupler, so I just pulled one side of the tongue in a little bit to make both sides equal.

I have no idea if this is a problem with current models. I am certain that if I were replacing the axle (Henschen, Dexter, or otherwise), I would check to make sure the frame is square. It only takes a minute to measure.

I would be especially concerned if the trailer had ever had a shell-off floor replacement. Very easy to get a racked frame while putting on a new floor.

Ok...starting to make sense to me now. I dug out my '73 service manual, and read the procedure for alligning the axles. Its hard to follow, though, as the illustrations in this section are photographs, and since it crappy repro manual, the pics are basically illegible. But anyway, they've got special guages for measuring the camber/caster and toe of the wheels. and another special axle bending tool that is used w/ a hydraulic floor jack to bend the axle at certain points if the measurements are off. it even comments in one section that you may have to cut into the belly pan to bend it far enough.

now, I'm wondering if this extra allignement is only necessary if uneven tire wear is noted. (a discussion of the types and causes of different wear patterns preceeds the allignment procedure in the manual).

my 9-year old tires don't show any wear at all, fwiw. they still have those "new tire hairs" sticking out around the tread. (we don't get out much, I guess ).

interesting thing I noticed: they refer to the axles as "duo-torque axles". and its not just a single typo. they're referenced the same way several times.

Great, I needed something else to worry about. I think there is a Groucho Marx joke in there somewhere but I do have my standards.

I think you're 100% correct. If you don't have unusual tire wear, everything is butiful.

As far as those measurements go, camber is set by the axle manufacturer, toe in should be 0, +/- 1/32", and I have no idea what on earth caster is, or how you would measure it, on a duo-torque (sp) axle. It's a number that just doesn't make sense to me for a swing arm axle.
