Is this a characteristic of the rods in the axle being worn out? How do I know what type of axle that we have? I am driving over to our storage area to see if I can determine the range of motion, as you suggested.
Please read the following article.
Dura Torque Axle
If the shock studs on the torsion arm are hitting the axle mounting plate, then that's not good.
The shock brackets can be bent outward to stop that problem.
However, in the absence of a photo, I can only sort of guess what the problem is from your description.
Any torsion axle that is not exercised to a reasonable degree, can develope two problems.
The first is that when the rods give out, and the trailer settles towards the ground. The position of the torsion arms answers that question. When the trailer tires hit bumps, the torsion arms bottom out, sending severe shock to the trailer chassis and shell. That in turn results in ultimate chassis failure and damage to the shell.
The second is that the rubber rods can "solidify."
When the rubber rods solidify, they are very hard and offer very little shock absorption, when the trailer tires hit bumps. The bulk of the shock absorption is then within the tires themselves, which is not a good idea. Blow outs are caused by that.
Setting for 5 years, normally, is more than enough time for the axle rubber rods to have failed.
