Ever trying to learn.
Torsion axles can "bottom out" when the rubber rods have deteriorated.
As an example, if the torsion arm can move 3 inches when new, that dimension decreases when the rubber rods age out.
That dimension can approach zero.
Two basic things cause the rubber rods to fail.
1. Age. Torsion axles, if used properly, can last upwards of 30 years or so.
2. Lack of use. Rubber must be exercised to stay alive. Parking the trailer or the tag axle motorhome home for long periods, is the culprit.
Parking the trailer for long periods of time, can be successful, within reason, but only if you remove the weight from the axles.
