After getting an “alignment” from a local shop and after giving them the paperwork instructing them on how to mess with the caster with the SPC control arms I noticed my rig started pulling right a week after getting the alignment.

Upon further inspection the shop did not adjust the castor position on the UCA but with the LCA.

The post alignment castor was 2.4 degrees but his machine says “3.5” now.


I am using quotes because my before and after alignment numbers are pretty shady. The before numbers are pretty symmetrical but I remember one tire had really bad positive camber while the other tire looked fine. The steering wheel stays slightly to the right but the post alignment numbers all match and are within spec.






Is it within Toyota spec to have both cam bolts in such a far range from one another rom back to front?

Try finding another shop that'll spend a little more effort on this.

This is one of the reasons why I don't like the SPC's as it's asking a tech who's just looking to get you out the door as quickly as possible to do quite a bit of extra work. I've personally aligned with these and they do take time and effort to get right. If those UCA's are not symmetrical then you run into the problems of the lowers not being symmetrical if there aren't any issues (i.e. - bent components).

When I got rid of my SPC's for JBA's I reset all of my cam's to the middle before heading down to the alignment shop. My settings were all pretty much symmetrical afterwords.
