axle gauge

We made this mockup to show the difference in the height of the trailer, depending on the position of the torsion arm.

You can also see that with a starting angle of 35 degrees you gain about 1 3/4 inches in height from a starting angle of 22 1/2 degrees.

The actual dimensions in this mockup, from the torsion arm being at zero to the various down angles is as follows.

5 degrees = 1/2 inch
10 degrees = 1 1/8 inch
15 degrees = 1 3/4 inch
22 1/2 degrees = 2 3/4 inch
35 degrees = 4 1/2 inch

that is a good guide to place on the shelf at the shop, but i think you could do a paper or cardboard guage and sell them to the public and it could be used at my house.
Just a thought.
Thanks again for the info
Jerry

Nice gauge. Ruins my long held faith in trigonometry though.

Oh well, just so you still believe in Airstreaming.

Everything else is gossip.

My compliments, Andy. Great illustration tool. Gotta admit, my first thought was how far apart the wheels were, as in railroad track gauge. I’m sure that Terry will appreciate this too.

Hi guys.

So, Andy, tell us....is there a factory specified minimally loaded angle for the Airstream axles?

3" lift with new axles

The new Henschen axles raised my 1976 31" Sovereign by about 3". I am amazed. Here is the before and after picture. Also look at the old axle on the ground, the torsion arm is frozen in the level position on both axles. The tires did not drop at all when I jacked it to start installing the new axles. I finished installing the P-3 brake controller today and will take it out for the first test drive in the morning with the new axles and Kodiak disk brakes. I can't wait to check it all out.

Don,

If your trailer was raised 3", don't forget to readjust your hitch.

I think I am good shape. I bought a new 2008 Suburban last year and had to replace my old Hensley Arrow 4" drop bar with an 8" drop bar. The new Suburbans have a higher hitch position that caused the need for the longer drop bar. But even with the 8" drop bar I was still riding a couple of inches high in the run when hitched. Now everything looks level. Here are 2 pictures from both front and back hitched.

Nice Job ANDY. I did not measure before I change my Axles but I'm sure we gained between 3 and 4 inches in rear height.
Steve
That was the first thing I notice after I changed my axles was the rear of the trailer was high. I checked the levels and sure enough It was about 4 inches tongue low. I was running a BLUE OX 4" drop receiver because the 1ton was to high.
I now have a BLUE OX 4" receiver drop for sale and the trailer is level.
Amazing what new axles will do.
