Axle replacement, rebuild

bmklawt · 11-30-2008, 03:40 PM

The first of many projects

I noticed my axles were in the horizontal position so I thought I'd take a look and see how bad the are.
When I jacked the trailer up the the tires didn't stay on the ground they moved right up with the trailer, after removing the wheels I found the spindle arms to be locked up solid with zero movement. I also found the shocks were shot they are regular automotive shocks and not the kind the can be mounted horizontally.
Off they came and in the next few weeks I will be traveling to Indiana to pick up new ones at the same time I will go to Palomino Parts in Colon Michigan, for a new water heater and furnace and to Goshen Stamping in Goshen Indiana and pick up some lift parts for my popup.

Here's a few pics of the axle:

Are you saying if you put a floor jack under one of the backer plate flanges and jack up against it that the spindle will not move before the trailer starts to lift. How about a 2x4 over the trailing arm and pushing down against the frame. Any movement there?

If no movement in either direction I would think the axle may have rusted tight. I can't believe the rubber rods would harden to that extent.

Are you sure you have enough jack stands under your trailer!!!! Would hate to see you bend things... Also take all unwanted stuff out of trailer.... Good Luck! Vin

As soon as the trailer started lifting so did the tires, I did not think to try to pry them with a 2X4, I did try to stand on the spindle and got nothing.

I have 9 jack stands under there but only 3 are holding up the trailer the others are just touching and the stabilizer are down with a smidgen of pressure.
Its been 5 days now and so far no settling of the trailer

IMHO if you have no movement on the arms either direction, the rubber rods have set and therefore you have no suspension. Our old axles were just as you have described there was zero movement in the arms in either direction. When you are towing you probably notice a lot of bouncing from side to side indicating that your tires are providing the suspension.

Wow...sure looks like the road salt has done it's damage to the undercarriage of your AS...The 78 AS we bought this summer was based in Central Calif, where we don't have to deal with road salt, and has almost no visible rust...

We did change out the axles, however...they weren't stuck as your's are, but were at the end of their useful life...what a difference in ride after the change!

The way your frame looks in the photos, I'd look into taking the time to applying some good rust conversion material before installing the new axles...POR-15 makes some good rust converter stuff, as do others...it's fairly easy to apply, and it will stop most all future rusting...

Your new axle rating should be 3000 pounds to 3200 pounds maximum.

Anything greater than that will give the trailer a rough ride.

The ideal starting angle is 35 degrees. A 45 degree starting angle is not meant for highway use, as it would punish the trailer.

Airstreams use horizontal shocks, available from Airstream dealers only.

I drove to Indiana today to Axis Products and picked up my new axles, OK there not new I had mine rebuild, cost less than $100.00 total but they gave me a deal for reasons unknown to me.
Said for 33 year old axles they were in very good shape except for the cords being shot so they put new ones in for me.

Also received a guesstimate of $600.00 for two new axles with 10" electric disc brakes and brake away, and somewhere under $1000.00 for two new axles with 10" hydraulic disc brakes, brake line kit, brake actuator and break away. Add about $20.00 per wheel for 12" disc and add $500.00 total for electric Hydraulic brakes. I also believe they told me $300.00 for a pair of axles without brakes.
They say they can build a direct replacement with correct mounting and shock support all you need to do is give them the information and with a little lead time you can bring your Airstream there and they will replace them for you.

My axles say 2600 pounds but they said the cords they pulled out, it was more likely 3200 to 3500 pounds they replaced them with the same length cords they took out.
The inner bar was an odd shape and not square which may account for the lower rating, just my thought.

Here's before and after pictures

Bruce,

That sounds like a pretty inexpensive way to get new axles. I wonder if anyone else does that?

Could also be a great way to get rid of old axles - send them to a rebuilder. I'm starting to smell an opportunity. Cha-ching$$.

**Kevin245** · 12-08-2008, 06:34 PM

Never thought these axles were re-buildable. Were you able to witness the process, and do you have any information about how they did it? A hundred bucks seem mighty cheap.

I have left you karma as the best single post I have seen in a long time.

Having been forced to replace my axles without the aid of competition I envy you. I question Henschen as to why they did not rebuild axles maybe now they will see the light.

bmklawt · 12-08-2008, 09:15 PM

I called all the axle manufactures and none but Axis said they would rebuild, Henchen wouldn't even talk to me, referred me to Airstream and Inand RV

I didn't get to see there operations as I had some running around to do picking up other parts for my Tradewind, I picked up a Suburban NT22SP furnace and an Atwood G6A-8E-6 water heater from Palomino parts 269-432-3271 for $508.80 a really good deal in my opinion.

Anyway from my talk with Axis it is my understanding they clamp the tube in some rig and rap a chain around the arm, heat the tube to soften the rubber and use a 20,000 pound press to pull it apart. The ball park figures they gave me over the phone were phenomenally cheap, but that was only if they could fix it which thankfully they could. The price could have went up from there had they had to replace anything and said they could replace tube or arms if needed. Axis, Dexter and Henchen all use the same size tube and inners, they could have and would have if needed replace the tube and use my arms or replace the arms and use my tube. (I think)

I got the feeling that they would not have as readily done this had they known the axle were 33 years old, and I would have gotten new axles had I known I could get them for $600.00 the pair but I didn't even ask because all my searching on this forum told me they would cost $600.00 to $1,200.00 per axle to buy new.

I may still yet get new axles as Axis thinks these my be a little stiff, I told them to replace the cords and that's what they did, only after the job was done did we talk about what the trailer weighs. That is my fault as I was not forthcoming with any information for fear they wouldn't do the job because of all the stuff I have read on this forum.
I over heard two of the guys talking that a 2600 pound axle uses 15"? cords and mine where longer in fact mine were longer than the square rod in the tube and they replaced them with cords 1/2" shorter than the piece inside. They told me the cord should not be longer than the inside rod or they my work themselves out towards the center empty space of the axle.

I spent about an hour with a gentleman named Kevin while waiting for the paint on the axles to dry, he explained a little of how they took them apart and explained how they work even drawing up some pictures on a white board so I'd understand. I mentioned the shock mounting and he shown me they have that all engineered for the Airstream's and that they can make a replacement for any Airstream 1970 and up, I imagine they could make an axle for any year given the right dimensions. He also ball parked me the figures on new axles and I took a mental note to report them here. He stated they are not set up to change axles on an Airstream in shop but if someone wants to bring there Airstream to them they will do it or build them on spec and ship them out saying we the customer pay the bills and one axle here an there will hopefully lead to 5, 50 or more axles there.

I give Axis Products two thumbs up

Rebuilding any torsion axle, carries a huge liability and invitations to law suits.

The internal part of the axle tube, in time, rusts. How much, is anyone guess.

Dexter, Henschen and others have been there and done that, and want no part of it.

Last word was that Axis would no longer build any axle for any Airstream
trailer, for a number of reasons.

Installing axles with 10" inch brakes on a trailer that had 12" brakes, is a huge step backward. That will be seen when the wear sets in.
