Took it to Firestone for alignment the guy said he could do it if he had the tool. I have seen three online, can you tell me which one I need to do front and rear adjustments?

83775 GM Camber/Caster Tool
83785 GM Camber/Caster Tool
J45845 Camber/Caster Adjusting Tool

Could you please provide instructions on usage?
Thanks

Hi,

Absolutely. You need J 45845. As far as adjusting the caster/camber, see the directions below.

Pics 1 and 2 pertain to the front. The remaining pics are the procedures for the rear wheels.

I hope this helps. Let me know if you have questions, or if there is anything I can do to help.

Take care,

Joe

Are there any directions and pictures for rear caster/camber adjustments as well?
And do you have the alignment specs for my STS, AWD 3.6 Base?
Thanks

Hi,

The caster isn't adjustable on the rear. Only camber and toe. As far as the specs, I attached them below. See pic 1. The remaining pics are for adjusting rear toe. The camber adjustment that I have are listed above.

Let me know if this helps or if you have other questions.

Take care,

Joe

About the J 45845 and J 45845 10
the instructions say use either the. J 45845 or the. J 45845 10
I found the J 45845 10. Online. Can the front and rear be set with the J 45845 10 tool .
I believe the difference is one end is longer than the other.

I know the J45845 can be used on both. I'm trying to picture it in my mind, and don't feel using the J45845-10 would be an issue. It should work. I believe the difference is the length and the "10" has the adjuster on both sides. Oftentimes, the ends are actually removable (unscrew from the handle) on the "10". That would basically make it the same as the other. Check to see if the tool you are looking at has replaceable ends.

Let me know.

Joe
