Bill,
What I saw at the dyno session was that the left wheel moves more forth and
back than on the right side.
I'm searching for the cause.
All bushes seem to be okay.
Your idea with different spring rates or broken leaves is a point to check.
Thanks

With hard bushing you shouldn't need a panhard bar--at least I don't. You might
want some kind of anti-tramping bars though. I use them on Peyote and they make
a huge difference. If the spring rates are a little different they will roll up
differently and steer the rear end. I'd suspect a problem in the LSD. Either
your spring washers might have heated up and softened or something is just not
adjusted properly.
