LOL........what's the question?

 

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?

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