Torsion Axles

My fifth wheel has torsion axles and I don't think they were specified for their smooth ride. It could be the engineers of your trailer wanted a low ride height or they needed the torsion axle as a structural cross member for the frame, both advantages of torsion axles. If you have tandem axles they are independent so there is no equalization between axles. Shocks are considered not necessary as the rubber cores are supposed to be self damping. As for wearing out, torsion axles have much longer life than hung axles as there is no metal to metal contact to grind and wear.

We had a problem with stuff falling out of cabinets with a lighter weight trailer with hung axles. We used tarp bungees with the plastic knob through the door handles to secure the doors to each other. problem solved.

Thanks. We don't have the owners manual, figured out what they were via Google. We may need to find a place who can look at it.
Thanks

Axles get completely replaced.
Here is what I found: It is certainly possible for any axle to wear out enough over time to need replacing. Since the suspension is built into a torsion axle if the suspension part was to wear out pretty much the only solution would be to replace the axle.

If the deflection, or amount of travel of the wheels, on the torsion axle has increased, caused the trailer to bottom out, or is not the same on each side then that would be a good indication that something is wrong.

Like everything they can wear out. Only way that I know how to tell is by looking in your owners manual to determine the loaded position of the torsion arms and compare that to yours. If they are further up in angle to the trailer then they are worn out. Also don't think you can repair them.

Depending on the roads trailers do bounce. I have draws on mine open and the dog kennel move around and I know mine aren't worn out.
