DIY Alignment? - Gyraline (1 Viewer)

Be good to do at least the basic toe and camber measurements (i.e. no turn tables) and share. Should be no more than an hour or two. Please…

Finally got a weekend off (from camping) this weekend. Planning to change all the rear control arms so alignment checks will be part of that. Standby.

Okay, spent a little time on this today and have some interesting observations.

The phone is going to have everything to do with the Gyraline experience. I have both an Android Pixel 9 Pro XL and an Iphone 15. The Android app and/or gyro is trash for this application and might as well be measuring with a rock. The Iphone 15 on the other hand provides useful measurements.

Gyraline on the Android is v2.2.0, and is clunky and might as well be beta software. It also does not pass the check device calibration test.

Gyraline on the Iphone is v 2.22.04, and much smoother and refined to use. I don't even see a calibration function, at least for toe measurements. There is required calibration for camber. I haven't tried body or caster measurement.

Couple tries for toe measurement on the Pixel Pro XL gives widely different results. The best of which measure alignment at the following. I stopped after a couple tries as it clearly wasn't up to par.

Iphone 15 was within a .05 on each run and measures as follows. Which is very inline with what I expect and aligned the car to previously.

Camber measurements on the Iphone were equally solid

Did you measure at least twice or three times with the iPhone the toe and camber?

Your results are odd;
- Negative toe front and rear (which will become more negative as you drive), while specs are front 0.0 to +0.2 and rear 0.0 (straight axle)
- Negative camber which should be zero rear (straight axle) and slightly positive front, although spec allows range from -0.4 to +1.2

Your thoughts beside throwing away that android phone... ?

My alignments from a shop show a bit of negative camber and toe in the rear. So I don’t think there’s anything wrong with what @TeCKis300 found with the gyraline.

I hear you, hard to explain though with a straight axle. The tool does produce a cross camber and that is showing zero. Your thoughts?
