WEIRD SAI numbers on 2005 Corolla Alignment Results Sheet

Aug 21, 2008 7 Replies

All other parameters are aligned pretty close to center of range, IE: Front Left Camber Specified Range is -1.3 to +0.2 degrees, actual(aligned) camber on that side is -0.7(green).



But the SAI gets real freaky up in here:



Front Left: SAI: Specified Range: 10.6 - 12.1 Deg. Actual: (in red)0.3 Deg.



Front Right: SAI: Specified Range: 10.6 - 12.1 Deg. Actual: (in red)1.3 Deg.



What the quack does this mean??



Since the red numbers are positive, does it mean the left SAI is



12.4(12.1 +0.3) degrees?

Ditto for the right?



Somebody help put this in English please? Thanks.

"SAI" SAI stands for Steering Axis Inclination. Do a search for what it is and hopefully you will find some illustrations on the geometric layout and how it is measured becasue there is too much to go into about it from here. But one thought is wornout suspension parts and possibly (assumption is) aftermarket offset rims installed.

Please Harley, FOCUS and read my O.P. once more. I know what SAI(fka "kingpin inclination") is. I just need someone to translate, from Arabic, Russian, or whatever, exactly what those actuals mean on my wife's alignment print out.

Thanks in advance.

Bad numbers or a bad check. If the caster is good, both struts would have to be bent pretty bad for those differences.

Righto, $6M. But the car is TIGHT. No pull toward either side, and a straight steering wheel. The car rolls with little effort at the gas pedal. This shop knows their stuff. So I'm just asking, do those SAI numbers indicate that the SAI is off by 0.3 and 1.3 degrees over or under the specified SAI range above?
