Another Axle thread (with pics)

Hi,

Looking to buy a 73 29'. Well maintained, but I think original axles. I read the article on inland RV, but it wasn't totally clear to me after crawling under the trailer.

Here is a picture looking from the front of the trailer towards the bach. Ti looks t me like they are shot, but I really can't tell if I'm reading Andy's article backwards.

any thoughts are appreciated so I can negotiate a fair price with the current owner.

As the torsion arm goes rearward, it should be pointing somwehat down hill.

If it's parallel to the frame, or going uphill as it goes rearward, then the rubber rods within the axle tube have exhausted their life.

There are data plates on the axles with the date of manufacture and the rating of the axle. This will tell you how old the axles are. In looking at your pic, I don't see any down angle. So it's probably time to replace. Figure in the neighborhood of $1500.00 for new axles, if you do the work yourself.

thanks, I'll check the angles and date stamps, but planning for replacement this winter. Hopefully it's OK to get 1-2 trips out of it from now until September and hten i'll call inland and see about getting some new axles, potentially upgrade to discs at the same time

The axles probably are bad, but every single Airstream trailer has axles at that angle when new from the factory. The angle at rest proves nothing.

The designed ride height of a 22 1/2 down start angle is horizontal, scanned from the original Henschen manual.

thanks Greg. This graphic would be for the rear axle, so the front axle would be the opposite. I believe that these axles are pointed up, so are shot as the end of the bar that the spindle secures to is actually higher than the frame.

Greg's graph, is for "ALL" installed torsion axles on Airstream and Argosy trailers.

There is "no" difference between the fron, center or rear axle, as the case may be.

My 3200 lb axles are in the neutral loaded angle with no hubs or backing plates at all. Literally unloaded with nothing but spindle and they are still neutral. I used a 6 ton hydraulic jack placed right up under the lift plate and it has about 4 1/2" of life and the tire was still on the ground ! ! ! ! !

Wish I had photographed them from underside before I pulled them off.

The graphic is for the left trailing arm, so the right would be the opposite.

Your measurements say that the rubber rods are worn out.

That means the trailer will bottom out when hitting bumps, no exceptions.

if the front axle is the opposite, you have an axle installed backwards. The arm always trails toward the rear....

Thanks everyone. I bought the trailer and plan on doing the axles this winter (want to order before Andy's summer sale is over). How much time will I save buying the axles "complete" vs reinstalling my brakes onto the new axles. Current brakes/bearings were serviced less than 1 year ago and work great. (looks like $300/axle price difference)
