no it's not. it's the acceptable range given that no two frames are
exactly the same. "compensation" has one side set different to the
other. that's /never/ speced by the manufacturer. and if it was, it
would be something like "0.5 - 1.0 right, 0.75 - 1.25 left", not "0.5 -
1.0" without stating the obvious - that the vehicle is supposed to be
moving in a straight line.

i don't know why you think i'm bull****ting you. all i'm doing is
giving you technical facts. the facts are that manufacturers do not
"compensate". some hick alignment techs do. they're wrong, the
manufacturer is right.

finally, i've asked you this three or four times, and at last you've
given the answer.

i think you need it if you can't answer basic questions and keep
bleating about drift and long after i told you it is, to some extent,
normal on a cambered road. and no, you should not "compensate" for it.

I never disagreed that some drift was normal on a cambered road - in
fact, I found myself trying fruitlessly to convince YOU of that, and
that I was GLAD that's all my Kia is exhibiting now. >smh repeatedly<

And I never said any attempt "should" be made, by the orig. mfg or a
shop, to compensate for crown. I just suggested that it might be
going on, and might explain the reason for the definite PULL my '03
Impala and '05 Malibu exhibited right out of the dealership.

You and I are definitely speaking different Englishes on here. LMAO.
Un... real..
