Bent trailer axles, how to fix????

Sooo, I inherited a 28' Gooseneck that my grandfather used on the farm for many years. He obviously overloaded it ALOT which has resulted in bent axles. It still pulls straight and true, but it wears the inside of the passenger side tires really bad and with a heavy load I have popped a tire due to deflection in the tire and rubbing the fender.

Any ideas on how to fix easily? Or is it going to be a real pain in the ass?

I have heard of people using a jack with a load or some form of pressure on the trailer to hold it down while using the jack to apply pressure to the axle then using a piece of angle iron to truss the axle afterwards. The best way would be to replace the axles though since they have a bow to them factory and are not perfectly straight to begin with.

I used to work in a heavy truck alignment shop and have fixed many bent trailer axles. The Bee Line equipment I used worked great for it. check a few truck alignment shops in your area get a quote. and then decide.

Shops that work on trailers should be able to re-align axles, in fact the shop near me that does it is Bee Line. It was something like $165 for two axles with tax. But it might be worth it to just get new bare axles.

I traded for some axles and tires some time ago and one of the tires was worn bad. When I took everything apart I found the tube rusted through and the axle bent. Its a crappy pic, but you can see the air gap of about 1/8" in about a 3 inch run. My plan when I get to it is to straighten the axle and plate both sides.

For what it could cost to get the axle "straightened out", by that, meaning putting the proper arch back in it, I would consider just getting a new beam and swapping all the hard parts over.

But if it's wearing on the inside... is there any chance the axle was installed upside down?

I have seen people remove the axles from mobile homes, shorten them and replace them with the bent/broken trailer axles ... those axles are designed to handle quite a bit of weight

I put some arch in mine myself with a large I-beam, some chain and a bottle jack.

That was my initial thought as well, but I looked and they are installed correctly, they have a factory arch in them as stated above, but it is the passenger side that leans in, I'll get some pics this afternoon of it to show you guys what I am talking about.

How much overhang from spring pad to backing plate? They sometimes bend there.

New axles would be the guaranteed, no fawking around answer. You will get exactly what you need.

I bent all four spindles on my tandem before (who knew limestone was heavy??).

I figured, yeah no prob, just pull the wheels and bend them straight again. Wasn't long after I lost one wheel, hub and all. Then I fixed it properly.


If it's your spindles that are bent, they're hardened I think and should be replaced, diff story if it's the axle itself, you can always weld it beefier.

I truly have not the foggiest idea, may take it to a trailer shop down here and see what they have to say.

Yeah, I need to price them, I'm afraid they might be more than the trailer itself is actually worth.

I think he overloaded it with a large backhoe, the poor trailer is a single wheel tandem with 8 lug wheels, so I'm assuming 7 or 8,000 pound rating. I truthfully dont know what to look for as being bent, dont know what they looked like unbent.

I have tried to bend them back once. never solved the wear issue so I just replaced the axles with new and never looked back.

This seems like a really bad idea. " Guess i will put some arch in my axles today"

If Jay thought it was a good idea to arch those axles Id be inclined to go along, the fact that you think it isn't just reinforces my belief that Jay was doing the right thing

Jay im guessing thats the trailer I saw at Naches. Was it spreading the wheels when you loaded it, or was it a preemptive measure? How did you decide how much arch to put in it?

The trailer we had this year was Ben's new 26'. This is Ben's old trailer, my new trailer. The tubes were straight, I won't say why. The last set of tires wore heavily on the inside.
I duplicated the camber I measured on a 1 year old trailer I have that has not been abused.

How is it a bad idea? Most trailer axles are cambered. These axles used to be straight and the inner shoulder of the tire wore out when the rest of the tire still had 50% tread. Now the axles are cambered so the tires should wear evenly.
