Regarding the suspension, it turns out that there is torsion bar
suspension, which hooks some way into the arm which supports the hub.
This arm a casting about 9 inches long welded onto the end of the
torsion rod. *The suspension is totally sacked out, so is just a solid
ride. *Even with both wheels off the ground, the suspension just sits
in the maximally compressed position. *The tire man said that usually
there is an adjustment bolt somewhere on the axle near the center
which adjusts the ride *height, but nothing like that was seen here.
I'm almost thinking that we'll have to grind off the axle and weld on
a new one to solve this problem. *Anybody seen this before, or have
any ideas?
TIA,
Ed

Ed, buy yourself a new Torflex axle of the correct size/rating (get
one with the electric brake flange on it so you can upgrade
someday...). It's an incredibly easy install, and your trailer will
ride like a dream with it's freshly recharged independent rubber-band
suspension and your ship will thank you for it. The elastomer bands in
these wear out over time (not as bad with newer techniques/
formulas...) and go flat as yours have. If you have elastomer
suspension (as it sounds like you have...) , there's no 'fix', there's
'replace'. The axle is only a couple hundred bucks though, and the
Dexter peeps are mighty helpful in the selection process should you
need to call them.

forum how fast my trailer has been 'stability tested' up to with one
of these axles, so lets just say waaay too fast ;-)
