Anyone know correct Z height?

[DavidAragon]

Hi,
I've been battling with my GM dealer here in town to correctly adjust my Z height on my 03' H2.

I just got it back again yesterday and he said it's at spec... BUT, it's exactly where it was before!!!

From researching it myself, I came up with a z height of 4.5" (taken from the web link that someone listed here)... Last I looked at mine, it was at 4" (not that a half inch is all that much but I want them to fix it the right way).

In order to drive straight down the road, I have to hold my steering wheel at about 10:30 instead of 12 noon like I would on my Jeep... That to me makes me think that something is still wrong...

Can anyone provide any help?

Thanks,
David
