Could someone give me a lesson on spindles? I don't understand the number rating etc. And what is stock on a '63 single axle Safari? Many thanks.

It attaches to the trailing arm of the axle. I don't believe they are replaceable on an Airstream axle, but we replace a ton of them on Blackhawks, Chinooks and Apaches in the Army. The backing plate is mounted to it and the wheel bearings and wheel hub/drum rotate on its axis. As far as size and ratings, I'm don't know. You'd be best off to call and talk with an axle manufacturer or distributor. My new Axis axles I purchased from Colin Hyde have new spindles.

Yup, Top is correct, spindles are not replaceable. They are welded to the end of the torsion arm which is intergral to the whole axle assembly.
Although the 6 lug Airstream axles are not notorious for spindle failure, 5 lug axles on Caravels are. They literally crack & the whole hub & wheel assembly falls off the trailer causing all kinds of body & floor damage.

Babyboomers,
Your trailer should have a nominal 5000 lb axle, de-rated to 4000 lbs. This size of axle comes with 12" diameter brakes with larger spindles/bearings than would typically come on a 3500 lb rated axle. The "5000" lb axle is actually designed to be assembled to suit requirements from 4000 lbs to 6000 lbs, so for your application, you'll have a lot of extra capacity in the spindle/bearing & braking department.
Hopefully this helps you out,

Colin

BabyBoomers,

I'm curious why you are asking about spindles. Has something happened to the spindles on your axles?

Or did you mean to ask about your axles?

Thanks everybody for the followup. I meant to ask about spindles. In the thread that I asked the question (the mod thought that it should have its own thread) the poster was asking about no. 10 spindles on their axle instead of no. 11, etc. I didn't know what it meant and what the capacities are.

Since I will be buying an axle someday and will have the opportunity to spec it, I thought I better know if I have some options! Many thanks.

Well, that makes two of us. Since as mentioned above, the spindles are part of the axle, yours was the first time I had seen any discussion of them on Airforums.

Roger that. Thanks for asking the question!

I'll try to find the thread where I originally asked the question. Maybe the Mod who moved it to it's own mat remember where he got it. BabyBoomers

I think what was meant was the axle TUBE is a number 10 or number 11. in some instances, a derated #11 tube was used so 12" brakes could be used.

Your original axle rating for the 1963 22 foot Airstream, was 4000 pounds.

Airstream kept that rating on the 22 foot trailers until 1965 when they changed it to 5000 pounds.

Changes in axle ratings came about from feedback from owners, regarding handling and payloads.

I would suggest you go with a 4500 pound rating, with 12 inch brakes and a greater starting angle, which contributes to easier hookup to your tow vehicle.

Andy

Babyboomers,

I moved it because the discussion in the axle thread ignored your question as you put it. The spindle size is not a choice. However axles size is.

And your particular unit as mentioned by Inland RV and Colin H is noted for breaking spindles when in service. (And other smaller units from the early 60's)

While there isn't a rating or a size description for spindles, there is for axles. Axle replacement is the option you have to correct the known problem with the spindles your unit has. And there are several threads on units like Bambi/Carvels, Globe Trotter,and Safari.

And I think that you are recommending 30 degree angle?
