Alignment issues

[JimLev]

Have any of you seen this before?
I had my 33 aligned today but the pass front wheel looks like the caster is way off even though the computer display says it’s good, but the printout shows the caster is 14.3º
The drivers side looks good.

They ran out of time to try to figure out why the display shows it’s good but the printout is off. They agreed something isn’t right and will re-do it.

Yes. Take it back. A dirty mirror can screw things up. That doesn't explain why the reading and the print out are different though. Does it pull/drift to the left? I would think so. That is very strange. That whole side will have to be redone.

Never too early to buy a simple level to measure camber.. and then you can calculate caster too. So much easier to play with this on your own. I have one from this manufacturer that is similar to this https://www.summitracing.com/parts/tnh-1100

I didn’t see any mirrors, just flashing LED’s.
It does drive straight but making sharp turns you can tell it’s not correct.

James, I have these 2 gauges. Not sure how to calculate caster, do you have a link?

The " mirrors" are on the things mounted to the wheels during alignment.

Yeah you have to measure camber at +/- 15-20 degrees. I’m not sure what the angle is.. I think it’s 15deg but I just use the angle on the tennhulzen tool.

Here’s the formula so you can do it with any angle:

James, thanks for the info. Just printed all of it.

Bruce, if you zoom in on the front wheel are those the 9 round circles the mirrors?

Yes. They really are specialized reflectors. The laser "cameras" on the machine can measure changes in distances for the dots and calculate the alignment angles.
