Some data on Henschen Axles

I was able to obtain this data from a good source ....

Henschen axles from 1974 and older used rubber rods that were susceptible to failure, because of the composition of the rubber. The composition of the rubber rods was changed in mid 1974 and continues today. While nothing lasts forever this change helped torsion axles to last much longer.

Rubber must be exercised to keep it "alive." Therefore if the torsion axle is under stress, and not used for an extended period, such as 3 or 4 years or so, the rubber rods "will" take a set in that position. When that set takes place, the axle no longer flexes as designed. This usually shows up with the trailer sitting lower to the ground when at rest as compared to a trailer that has been used on a regular basis. It will also show up as a trailer that bottoms out easily and does not cushion the load inside. Things are shaken up! The only fix is replacement. Using the trailer after the axle has taken the set does not bring back the life to the rubber rods. It may help, however the axle will not regain the original flex it had when new. And that applies to everyone's axle brand as charactoristic of the design.

The fix to avoid the problem? Use the trailer every year or so, this will keep the rubber rods "alive and well." And this is the same advise that Wally gave out back in the 50's and 60's for different reason! Get on the road!
