It is not intuitive to a lot of folks and particularly new RV'ers that beyond replacing bearings, tires and brakes that the axle itself would be suspect. Hopefully they will take the time to do some research on the net.
Unfortunately, newer members don't usually look up old posts.
Therefore, some subjects need to be repeated every so often.
There are two tests for torstion axles.
The first is visual, and the following teaches a person how.
Dura Torque Axle
The second and equally important test, is to jack up one side of the trailer, and observe how much the tire drops from it's loaded position.
The tire should drop about 3 inches or more.
If not, then the rubber rods have to some degree solidified, which says the axle is bad.
Lastly. all torsion axles, in time, will take a set if not used every year or so.
There are many 30 and 40 year old trailers, that still have acceptable axles.
Rubber must be exercised somewhat frequently, if not, it will lose it's memory.
