Torsion bars going bump in the night!

[Gerry Lehmann <lehmann@xxxxxxxxxxxxxx>]

There is a very mechanical reason why John =

and dug had different experiences with unloading
torsion bars before removing them.

The difference between things flying and
things not when the torsion bars are removed
has to do with their load (lbf/in) rating and pretwist
(sag) from age.  I have run into both in my travels. =

Softer(alfetta)/older bars need to have the
A-arm released as John described or they will
indeed go bang.  Stiffer performance bars have =

much less twist (travel) before they're unloaded =

so simply lifting the load off that corner
of the car is sufficient and you can just pull
them right out.  The crossover is somewhere
around a stock GTV6 bar so dug "lucked" out.  A
high performance bar can be done with just a bit
of jacking.  In fact,  Alan Bueno and I,  used to do =

front end height adjustments at time trials between
run groups.  That would be about 40 minutes for
both sides,  but we could only pull it off because
the Shankle bars required so little "unloading"
