Trailer Axle Repair.

Neighbor lost this torsion axle out from under his tandem enclosed trailer. The mounting bracket on the opposite side broke loose and this side ripped half of the bracket off the axle. I'm pretty sure I know the answer, but what are the odds I could weld it back together without screwing up the rubber too bad? You can see the rubber torsion goodies in the hole. I would have to assume the axle stub and rubber are put in after all the welding is done?

The trailer isn't worth a whole lot. I think a new axle is out of the question. His plan is to buy a new trailer for most of his deliveries and use this for local stuff when he can load up both trailers the night before. The other option would be a used axle another neighbor has, but it is too wide. It would have to be cut in the middle and narrowed up. That is assuming the measurement from the mounting bracket to the hub face is the same.

I've never torn into a torsion axle before, but if memory serves, you "should" be able to remove the hub and torsion spring (rubber), then make any needed welding repairs.

Then again, that's a fair amount of rust on that axle, and you cannot expect it to have the gross capacity that it had years ago. If it were me, I'd voluntarily limit my loads to no more than 75% of capacity; maybe a little less.
 
They are compressed into place (unless now smashed from age) and will be hard to remove and impossible to put back in. I would not weld it up. Too much liability. Jim
 
I agree with Jim, but if you must weld it, sleeve the entire axle in that area with a couple of pieces of angle iron and weld away from the exposed rubber, then weld the bracket to the angle iron.
 

Don't even think of repairing it. The trailer may not be worth much but you will be amazed at how little a new one will cost.
 
I think that is next to impossible considering that they are pressed together under extreme
hydraulic pressure and are never meant to be disassembled. They are meant to be replaced
not repaired. If you weld anywhere near the rubber it will destroy it. Junk the axle or the
whole trailer or take a chance on getting someone hurt or sued is my 2 cents. I have replaced dozens of them on goosenecks,cattle trailers and cargo trailers.
 
Do not try to fix that. It's not wo 4th the risk. A new axle tube alone should cost about $250 without brakes and hubs and then you will have it done right. You need 3 things to order thhat axle, the outside of bracket measurement, hub face measurement, and degree of angle on the spindle arm.
 

What am I missing here?
Everybody says you can't weld it back on, yet somehow it was welded on to begin with.
And a new axel will have to be welded on.

This is one of those weld an inch here, weld an inch there, wait for it to cool. Continue.
 
At the factory the axle is welded together
first, then the rubber parts put in. To
weld the axle to they trailer you do not
weld on the part with rubber in it.
 
Thanks guys. My initial response to neighbor was "no way I'm welding that". Then the more I thought about it, I though "well, maybe......".

I'll have him talk to the trailer place he's thinking about buying the new one from. Maybe they'll give him a decent deal on a new axle.

Do some searching on Line for trailer parts. All parts are standard trailer mfg to trailer mfg. Here in NH you would not got to a dealer for an axle.
