Replacing axles

[steamgauge]

I have a 1966 24' Trade Wind. The axle data plate says it is an Airstream axle rated at 2000 lbs with a possible part number of 2-712-742 mfg Henchan. The first 7 could be a 1. I am afraid to grind any more rust off the plate for fear of removing the numbers altogether. I need to know the Dexter axles and the down angle of the torque arms. Is it 22.5 or 32.

Thanks

You could order the same exact axle. OR you might choose to beef up the specs of the new one.

Some of the choice will depend on how you expect to use.
Infrequently, always on paved level surfaces.
Frequently some times on non-paved surfaces with possible of larger inclines or declines

At the risk of it sitting higher than desired I would opt for the greater angle. Years later these axles and the rubber springs inside tend to settle some and have a shorter service life than metal springs.

If you order from Inland RV in Ca. All they will need is the VIN #

If you order from another Dexter dealer you will need the following measurements:
outside of tires
inside of tires
hub face
inside of arms
outside of brackets*
brake to side of frame
number 10 or 11 axle**
shock absorber bracket?

*hi profile reverse mount bracket (for my 71)
** #11 axle is a heavier axle with heavier brakes. (my Tradewind has #10)

I also recommend ordering with EZ Lube bearings.

Pre 1969 Inland or anyone else will not have shock mounts attached. The records are not as defined for units that old. And some minor mods may be needed to install.

I replaced the axles on my 66 Trade Wind. My supplier was Colin Hyde out of New York. He served me well.

I think the majority of "dura torque" rubber rod axles are now made by Dexter. I am currently working on a 75 Airstream that needs axle replacement and will talk to Dexter first.

The original spec axle was a 22.5 degree starting angle. This is what I ordered for my Trade Wind. Colin's company recommend 2800 pound rated axles for my trailer. I think I would have asked for about 2400 pound rating if I had to do it again. My Trade Wind would never get to 5800 pounds gross weight.

Most axles come with 10" drums if they are less than 5000 pound rating. You can special order 12" drums if you want. Four 10" brakes are more than adequate for the Trade Wind.

I had some drilling to do to mount my new axles. Colin told me I would need to do so. The shock mounting stud on the swing arm was in the correct place, no welding needed.

Dura Torque style rubber rod axles have a life of about 30 years before they get hard as a rock and no suspension effect anymore. You are wise to get new ones for the good care of your trailer, less it rattle itself apart.
