1969 and up have 5 inch frames.
Torsion axles, re4gardless of brand, have a limited life.
That life is ball park, 25 years, if the trailer was used every few months or so.
The short life happens when the trailer was parked with the tires on the ground, for an extended period, any where from 2 to 3 years. The rubber rods, that MUST BE exercised, will turn gummy or solidify, in each case rendering them useless.
The following article will teach you how to check the axles out yourself, in just a few minutes.
