Um, no.
A live axle (aka "dead axle") is a horrible design compared to a properly
designed IRS. The Rotoflex coupling is an elegant solution to the complex
problem of locating the rear half-shaft - used anywhere from
the Formula Ford to Can-Am cars.
If you buy *real* Rotoflex couplings, built by Metalastik, not the
crap the Vicky Brit and others sell, they will last as long as the
u joints on a TR4A. I have both ... I know whereof I speak.
True, some folks prefer the stouter design of a sliding shaft with
two U joints. But it's heavier and has more parts that wear...
