The other photo is Airstream's manufacturing tag with specifications that read the axles are ALL 4,000 lbs. Obviously not. When I put on new MATCHING axles the clearance under my trailer increased about 3 inches.
Airstream would never deliver a trailer with 2 different axle ratings.

I would guess that the previous owner had a problem with one axle, and simply replaced it with whatever they found, and I would further guess, from a wrecked coach.

The 4000 axles are the correct ones for your Excella.

Dang it! Sounds like I'll be contacting Dexter axle real soon. maybe a new axle will ge me another inch. It will be interesting to see how this plays out. I've hit certified scales fully loaded. So I've got some numbers to look at. I'll be looking unto the torsion arm angles. Thanks

Hi Andy,

I admire your loyalty to Airstream, but the truth is that the lighter front axle was original. The dimensions of that axle's tube were smaller than the heavier rear axle, and so when we installed the front axle's replacement we had to grind out a larger opening in the mounting plates. We didn't have to do that with the rear, it was a direct replacement. I think that proves that two different axle ratings were installed by Airstream.

If you ordered it yourself, make sure the starting angle is higher than when new, and that the mounting bracket and hub face are correct.

Also, the new axle will be minus the shock brackets. You can cut the old brackets off and reuse them, or get a couple of new ones.

Got my trailer picked up today from the local wheel and axle shop. I need to clear up a couple things. First of all I learned my trailer, 2013 23' sport has a 10 degree trailing leg axle. Pretty much everyone agrees it can point upward a little bit. Other things here about my trailer that may not have been completely clear at first. Trimming along the aft edge of the wheel well lower aluminum trip was only done as a precaution. As to help prevent the newly replaced 16" wheel and tire from contacting the trailer. Don't think it could have, but not I'm confident it will not. So anyway back at home with my new axle, brakes and bearings etc. My next purchase will be a new drop hitch, the one I have now is a little bit to low. My recommendation after all this is that if you are reading all this seeking info on additional ground clearance for your trailer. Than figure out what axle you have and what Torflex start angle your trailer has. Again mine came with 10 degrees down. For additional height consider replacing the axle with a 22.5 re 45 degree down start angle. I got ground clearance the cheap way by adding the drop kit as discussed earlier in the thread. I would have done it differently if my axle would have been older.

45 degrees is a no-no per the Henschen engineers.

32 to 35 degrees is the greatest down angle they said was fine.

My 2013 22' Sport looks the same way, if anything slightly worse. Does anyone have the price for a new axle? My metal "guard" around my sewer drain is bent pretty good.... It seems to be that or the lift blocks.

I realize this is an "old" thread...but I"m curious about the "metal guard" for your sewer. Do you have a pic?

I'm also curious about all this swapping-out of axles every few years or so...
In my experience with my boat propellers, the center, rubber-hub could be replaced by prop shops (using a hydraulic press they press out the old rubber torsion material and lubricate and press in a new rubber. Why isn't that available instead of having to purchase an entirely new axle? ..or IS it available?

Axles are assembled by soaking the rubber rods in liquid Nitrogen then rapidly assembling the parts using special tooling. Once it's together, the rubber warms, expands, and permanently locks everything together.

It's just better and easier to buy a new axle... They do last about 25 years or so, I've been told.

I can get a picture for you, but it is just a large metal L bracket with a hole in the side for the sewer pipe to go through. Doesn't protect it from much other than a small road hit.

I just put the spacers on my '13 sport 22. The factory axel is a minus 10. I checked out brand new ones at the local-ish dealer and they are the same. the only issue I had was that some whizbang at the factory ran the propane line between the axle tube and bracket.
