Front End Alignment Question

[BlueRado]

Hey, if anyone out there has the current '03 front end alignment specs for the '03 half-ton 4x4 rado/sierra, I'd be very grateful.

 

Just trying to verify whether dealer is feeding a line of BS.

 

Thank you.

Caster is relative to frame. The caster values must be compensated for the measured frame angle. Frame angle is positive when higher in the rear and negative when lower in the rear. Refer to Front Caster and Camber Adjustment .

Thanks a bunch, asepgrad98!  :thumb:

 

Actually, my dealer was right on w/ the spec.  Said the right caster was supposed to be +4.5 deg. vs +3.5 for left side to "compensate" for road crown, assuming you drive more often on the right of the crown (reasonable assumption).

 

Of course now, it won't track straight on a flat surface, but it's not off by much.  Guess it's not an issue really.

 

Thanks again.
