Sorry, wasn't really asking a question but thought I would just post it for guys not having the manual or needing this repair done.

This will be some good information that I can arm myself with when it comes time to have the International's alignment checked.  I will definitely be bringing this with me to hopefully help the tech out...and therefor myself.

I don't think there is an auto manufacturer who where their current models are concerned uses a + (positive) setting for either the front or rear camber.

General handling purposes are now usually a - (negative) camber setting. Much better handling characteristics than any setting at a + (positive) camber angle

Interesting.  I suppose better handling and sportiness is the goal now.

Kinda depends on the suspension geometry.  If the suspension tends to go negative when the spring is compressed, a static positive setting MIGHT be appropriate.

But I don't know if that's the case for an Olds Cutlass.

 

I entirely do not understand how the "Service Checking" camber spec is -1.5 + or - .5  (Range -1 to -2) while the Service Setting is +.75.  Doesn't make sense to me.  ESPECIALLY since the Caster and Toe "Checking" spec and "Service" spec are essentially the same thing.

I suspect an error in the service manual spec for camber "service" spec.  Should be -1.5.

You noticed that was well....

in my 91 service manual the *service checking* angle is +.10 (or) 1/10 degree positive ...plus or minus .5 (or) 1/2 degree

service setting is + .5 degree...plus or minus .5 degree

So...what should I do here guys come alignment time at a shop?  Take all this info with me?  Do you think they'll have specs saved in their system for our cars?

[55trucker]

Any alignment shop will have the cars specs programmed into the racks electronic head unit. That shouldn't be an issue.
