Got a 4-wheel alignment at Infiniti dealer (had other service needs had them take care of it all) after buying new tires elsewhere. 2006x, square setup, 235/45/18 on 18x8.5, offset +44.

See attached spec sheet. A lot of green except for the front left, where nothing changed on two items, SAI and Included Angle. And they seem way out of range. Whatzat mean? How bad is it for long term tire wear?

I didn't have time to ask questions when I picked up the car; the service advisor doesn't know the tech anyway and I couldn't wait around for answers from technicians. So I thought I'd ask here for some insight before I call them and talk about it.

Thanks for any help offered.

 

This lays out definitions for the different terms: http://www.aligncraft.com/terms/terms.html

It says that SAI is not adjustable and that deviations can be from a result of suspension damage. So it's possible (and likely) that the compression rod bushings are worn, or maybe you whacked a curb and bent something slightly.

To me, something is up on the driver's side, I'd probably have it looked at.

 

Thanks for that great reference. I'll dig into it tonight. A little more info:

State inspection came around at same time I needed the tires. Had my trusted mechanic look closely at suspension while doing inspection. They advised compression rod bushings were cracked. I have Infiniti Elite warranty so that's why I was at dealer. Both compression rods were replaced under warranty. So it should be something else messed up unless there is a way to screw up new compression rod installation.

 

OK if I'm reading the chart right, it looks like the most likely issues are either strut top or bent control arm and bent spindle or strut body. The diagnosis is actually for SAI less than specs, camber less than specs, included angle less than specs. The camber on the left front is shown as within spec, but closer to being on the less side than the high side, so I have to go with the less less less diagnosis. There is no less, equal, less diagnosis in the chart.

I'm assuming I'm using the strut chart and not one of the others. None of the charts have the combo that I have; this is the closest choice I can make.

 

Its a little different from the stock





This is stock idk if the other one would wprk for my car help!! Plz<br/><br/>
