Also look at the difference from the gap in the top of the washer slots from front to the rear (brake line is rear). The lower the washer is on the pin, it pushes the arm out. So the front is pushed out father than the rear. That is the positive castor angle. :)

I am backwards here, the lower the washer is on the pin, it pushers the arm IN.

I spent ALOT of time on this this weekend. I am VERY close. I got the camber close as I can, caster close as I can. I used a dial caliper to match the pin settings for the castor in reference to the factory plastic locators. Then did the toe adjustment. Took a test drive Sat night. Wheel is a off center a little but it drove pretty good.

I fiddled with that offset steering wheel position today with some minor toe adjustments like @iamdub explained, equal adjustments on both sides and got the wheel straight. Seems damn close. Tonight I am going to go to the warehouse flat floor and do another camber check all around and see where I am at.

I did find myself running out of positive camber adjustment on the r/f FRONT keys. So I had to push the rear of the arm out slightly and lose a fraction of castor in the process. I am also having issues with the r/f rear arm camber setting. As I torque the bolt down, the degree reading wanders in the process. None of the other 3 bolts are doing that so I am scratching my head on that one.

Very close!

Would Those factory inserts help hold the plate/washer and keep it from moving while tightening?

Maybe use a C-clamp or vise grip on it?

They won't fit unless I put it back to the original ride height. Which is still an option but I am trying to avoid.

If you still have the original 17” Goodyears (QAS):
Caster: 3.2* Left and 3.6* Right
Camber: -0.1*
Total Toe: 0.1*

Your airbag recall is still open as well.


So damn close. Read about an old school trick of zeroing out the scale wheels straight then turning the wheels 15-20* to get rough caster measurement.
