If SAI is LESS than specifications, and camber and the included angle are also both LESS than specifications, the position of the strut tower may be out at the top and/or the strut, knuckle or control arm may be bent.

 
If SAI is GREATER than specifications, and the camber and included angle readings are also GREATER than specifications, the strut tower is leaning in at the top and/or the spindle or strut may be bent.      
 
If SAI is GREATER than specifications and camber is LESS than specifications, but the included angle is on the money, it’s a sure bet the strut tower is leaning in at the top.
 
If SAI is LESS than specifications, but the camber and included angles are both GREATER than specifications, the strut tower may be out at the top and/or the strut, control arm or knuckle may be bent.
 
If SAI is LESS than specifications, camber is GREATER than specifications and the included angle is correct, the problem is an out of position strut tower, bent control arm or shifted engine cradle.
 
Uneven caster side-to-side creates too much cross-caster that can make a vehicle pull or lead towards the side that has the least (negative) caster.  The underlying cause may be a bent strut, spindle or mislocated strut tower.
 
Sometimes road crown can cause unwanted pulls or steering centerness issues. You can adjust the vehicle to compensate for road crown by making sure the left caster is more negative than the right (not by more than .5) and making the left camber more positive than the right (not by more than .5).
