Will 2004 Henschen Axles fit under 1971??

Hi there,

does anybody know, if Axles of a 2004 28' Int. CCD will fit under a 1971 29' Ambassador without modifying?? We could probably get them really cheap overhere. Importing new Axles to Europe is no option, as that would be way too expensive.
If they won´t fit we have to install european axles with surgebrakes...

Thanks for your thoughts!

BTW: I have send the same question to Henschen, so maybe I´ll get an answer from them. Airstream was not able to answer this simple question...

BJoern,

I am certainly no expert with axles so anything I say has no basis in science or fact. That has never stopped me before, so I don't see why it should this time either.

This is out of the box thinking but not that far. They are Airstream axles so the only thing that matters is will the structure fit your frame. The basic things that are critical are the distance between the support structures and the bolt pattern. The support flange has to fit the frame width or fairly close. It can probably be shimmed if not too far off. The bolt pattern is what it is. If not a fit, holes can be drilled but this surely weakens the structure.

Good luck, I would try it expecially if you not goint to be driving thousands of miles like we do here in the states.

Flaming now begins.

Joe

Bjoern,
The only thing that wil allow or prevent the axle swap would be the location of the axle plates that are attached by welding to the axles themselves. First, measure the inside of the locator plates of your present trailer. Then measure the outside measurement of the plates on the axle. If the measurement on the axle is the same or slightly less (say an inch or so, I would go for it, using plate steel as a shim or spacer. If it is greater, then you can just mark that one off.
Under no circumstances should the plates be removed and rewelded to the proper location on the axles as it will compromise the integrity of the rubber cords which actually are your 'springs'.
As for drilling seperate locator holes in the plates, just two holes per each wouldn't substantially effect the stregnth of the plate.
I wish you the best, however, I do not expect the measurements to be acceptable.

No,.... 2004 is a wide body and the axle brackets are 67 7/16 apart", 1971 is 61 3/8"

Are you sure that 2004 is wide body this becouse this unit is imported to europe
and there is NO way we get the wide body licensed.
I don't think that the guy that has the 2004 would make a mistake like that.

Axles

I don't have the specs on a export unit, but if his frame measures 61 3/8 outside the yes the axles will fit, except for the rating. All Henschen axles have a tag on the tube that state the weight rating.

Thanks for the input!! Seems that we have to take the expensive route and change everything to german axles and surgebrakes...

Surge brakes should "never" be used on any travel trailer.

There is no way you can apply "brakes" only to the trailer, should you develope a sway condition.

Henschen does have replacement axles for your trailer.

That are our great european rules.
A lot of country's don't alow the US electric brakes.
Trailors up till 7700 LBS all have surge brakes overhere.

Tap the brakes of the TV. The TV slows down and applies the master cylinder and applies the brakes for a short period and takes out the sway. Stop accelerating and the same thing is accomplished just in a longer time frame as in a second versus a 1/4 second. The heavier the trailer the better this method works.

Andy, thanks for your input, but sorry to say - Surge brakes work!! And they do on ALL Trailers upto 7700lbs in Europe! Are electric brakes better? Mostly yes! Are they allowed over here?? Mostly NO!!!

I often drive trailers with surgebrakes and to stop sway it is just the way Action described - Tap the brake for a short time and sway is gone. To prevent sway we mostly use antisway hitches and please keep in mind we tow at safe speeds, which means around 50 to 60mph.
Why we do that?? Because Speed kills...

I know that Henschens and Dexter have replacement axles, but shipping them overhere costs just way too much and gettig an approval for them would mean that we have to register our trailer in the UK which is another big hassle to do - and after that you areonly allowed to tow the trailer with the TV that was registered to the trailer. With surgebrakes we can tow it with any Car that can take the weight...

Again thanks for the thoughts!!

Diskbrakes are available and are on our list, if we convert to EU-Axles... Axles with 3900lbs and diskbrakes are around 600,- euro ($470,-) each for Rubbertorsion Axles.
