[s-cars] Really bad caster

[Vincent Frégeac]

I did not disconnect the control arm from the antiroll bar, I just
disconnect them from the hub.

yes, i think that is more likely than your pushing the mercedes.
caster is the angle at which the steering axis tilts from the vertical,
viewed from the side.  i don't know what spec caster numbers are
supposed to be, but from what you're saying, i gather the caster
has increased.

that means the balljoints have moved forward with respect to their
original positions, increasing the inclination of the steering axis.

when you reconnected the control arms to the antiroll bar, could you
have overtightened the nuts?
