Tiedown Engineering torsion axle question

[opie]

I have a Load Rite trailer with Tiedown Engineering Eliminator torsion single axle. Anyone on this forum using this type of axle? Many different trailer manufacturers use Tiedown's torsion axle.

I am wondering when you can tell if the axle needs replacing because of rubber cord fatigue.
Thanks,

Here are my pics of the torsion axle.

I have an AL-KO Kober type of shaft and yes, it needs replacing rubber cord. After 20-30 years or so my dealer told me.

Clever design. If you are in a climate like mine where you lay your boat up for 6 months, you could jack/prop the trailer up for winter and extend that life by 2x I bet.

In any event, 20 years is forever in trailer life. I guess you could watch to make sure the tires arent hitting the boat when you trailer. Even if it sags a bit, you can adjust the torsion arms to compensate I imagine

My boat has always ridden low, but I bought it used...
The ride is sweet though. Never any bouncing over a bump. Just the normal down and up and then stable, like a good shock absorber. And, no adjustments at all possible. I wonder as well if the cords could just slip around and leave my trailer on the ground. A Google search turned up no such issues... I guess I'll wait 20 years to replace it then.....
