Vincent,
that or the antisway bar is bent. Unless the shop did not measure it
properly. I'll tell you what, why don't you measure the distance from
wheel to wheel on both sides and post it here. I will compare those with
my '97 with a perfect Caster. My line of thinking is you couldn't
possibly disturb the geometry in the top strut mounts, so it is in the
lower control arm. Thus the simple measurement should reveal the
discrepancy, if any.

And.... since you are a Canadian thus the real measurement units are
native to you, please post the dimensions in mm.
