alignment specs/SAI odd

[Zimm]

The primary angles below track just fine on 2 lane and highway, with the tire PSI set to the high 40's. So, if you're looking for target numbers, these may work for ya. Needing tires at 36psi always seemed odd to me.

After a dealer alignment, and now an independent realignment the car still pulls left. Check out the SAI....

Anyone have any SAI numbers from an alignment they care to share?

My sheet doesn't show a SAI so sorry no help here...

Just going by the final numbers shown that seems like a lot of caster has been dialed in? 2 degrees is the nominal factory setting I believe unless IA has changed the specification recently to help stem all the complaints of lack of steering wheel centering? I’d be curious to see how sharp of angles your front driveshaft CV’s are running at now as more caster will push the front diff pinion even further down.

Steering Axis Inclination (SAI) does seem to be off quite a bit from side to side and could be contributing to the pull did front suspension take a big hit off-road at some point? I’m no expert but for most alignments you want things to be mostly symmetrical from side to side otherwise it may indicate bent or incorrect tolerance components. Sure, there are certain older models of vehicles where slightly different specs side to side were used to account for road crown or vehicle loading but I don’t think that is the case here.

I’d seek a second or third opinion on it for sure as the rear axle could be a bit straighter so not to introduce a crabbing angle although it’s not far off.

Those are some pretty sloppy axles you must have there.
