Replacing axles is not a big deal.
There is a new type electric brakes that are self adjusting, which keeps them at 100 percent, at least until they are worn out.
If the torsion arms don't move, or move a small amount when the weight is removed, suggests that the rubber rods have solidified. The tire should move about 3 inches, when the rubber rods are OK.
If the trailer was parked for 2 to 3 years or more, that then is the reason for the failure.
Rubber must be exercised to stay alive.
Replacing axles on a tandem trailer, does not even require a jack.
