Thought some of you who do home alignment might find this a good, new alternative.

Interesting.

I question the accuracy and repeatability of the iPhone gyro angle measurements though. In my offhand experiments then seem to have a decent amount of drift (a few degrees over 5-10 rotations) which to me would render them impractical for vehicle alignment purposes.

Have you ever tried to align your car at home with strings and tape measures? This is probably at least as good as that. But, who knows?

If you want a super accurate alignment, put the car on a rack with lasers and a technician that knows what they're doing. However, if it were that easy, you'd feel comfortable that your car was properly aligned every time.

Actually, it would be great to see some amateur use this tool to align a car and then put it on a rack to see how well they did.

I love it... look at the picture. Basic 3D printed part printed on a $99 home printer... "Lifetime" subscription to a company who you don't know if it will exist next week...

But crazy expensive.

Jack Standz.....string alignment is very accurate, race teams use it every day at the track, fast and simple. Best, Mark

I was taught how to string align by a Wizard!

String alignment is MORE accurate than alignment bed IMO.

And more "repeatable"...

The only way you can see bed variation is to do a "perfect" alignment on a bed, test drive the car (where you notice problems) and chuck that car back up on the exact same bed, then have different numbers...

It ALL depends on the technician for either process.

He preferred string over bed any day.

I'm not so sure about the I-phone set up in the first point.

It looks like a $20 piece of plastic with a subscription...

I'll wait till I see results from others!

All of the current wheel balancers have a computer making the selection of weights and their placement choices for you.

The previous "style" had two analog needles showing amount of variation and placement.

Once again, you DID have to know what you were doing!

The new balancers allow a monkey to do an "acceptable" job...

You could balance wheels to much lower tolerances with the old school balancers!

But, actually that wasn't my point. Yes, string alignments can be accurate when done right. What I'd like to know is whether this tool will produce accurate results. Because it looks fast and simple to use even by a luddite like me (just add your phone).

Faster string alignments? Not in my experience. It looks like this Gyraline should be faster.

Accurate? Sure, but only with a good competent technical performing the alignment (counts me out (IMG:style_emoticons/default/smile.gif) ).

Simple? Almost perfectly setting up the strings and other things for an alignment versus pulling the phone out of your pocket and holding it in a plastic case against each tire.

The download for the android version is free thru 10/29/24. Would like to hear from someone that can verify how accurate you can get with it.



BTW I do have some experience with using strings, tape measures, chalk (running line down the center of the wheel when measuring toe), etc. to perform alignments with my dad (good memories). That was over 50 years ago, but it worked.

I go even simpler now-a-days.

Most vehicles don't have caster adjustments, and many don't have camber either.

I use a digital level and a couple of Jenga blocks to take camber measurements from the edges of the rim.

I use a tape measure across the tread to adjust toe. You have to find a repeatable spot to measure.

I use an 8' fluorescent light bulb to make a determination on which side to adjust.
This is used across the tire in the center.
Makes it EASY to see which tire is pointed wrong.
The light bulb method is the single easiest way to achieve a nice straight steering wheel IMO.

For 90% of the vehicles I hit this works fine.

I do tell my customers "Get a real alignment".
Some do...
Many have told me "They didn't have to adjust anything"!

This way does not catch caster at all.

All of this depends on having wheels and tires that are straight and don't have funky bulges on the sides.

All I do is spin them with some kind of hardline reference behind them but in my view.

The human eye can see variances below .001"...

I can always tell is the wheel/tire is straight enough for this method to work.

Aggressive tread off road type tires are the hardest to do this with.

Those home alignment books are great! I use the strings for toe adjustment and I use a Smart Camber tool for Camber adjustments.

Tire store alignment-Set the toe, let her go!

Buy one of THESE, learn to use it, along with the strings to set toe. 100% accurate and do-able on a semi flat concrete floor. Next best method to adjust toe is TOE PLATES.

One thing that is nice to have but not totally necessary is a pair of turnplates. Some 12" asphalt floor tiles and a garbage bag works nicely.

Then there is corner balancing and bump steer adjustment that should be addressed before any track alignment.

Above is just my opinion, YRMV

Yeah, and you get a great looking phone case. Looks like you can align and then head out for lunch knowing that it will be all right if you drop the phone.
