What's even more strange is if you look at the document ID #1547034 in the bottom right corner, it's the same on both of ours. So, maybe it's a difference in version of the eSI? This is what I have:
Service Information updated on 2005.02.21.
I even compared individual years - 2003, 2004 and 2005 both awd and rwd to see if there was any difference and they are listed as 140 lb ft.
I also found this:
Info - Recommended Wheel Nut/Bolt Torque Specifications #02-03-10-008 - (Dec 17, 2002)
(Astro/Safari = M Platform)
As a last step, I even logged on to my library's e-repair service which is the same data as the eSI manual and which you'd think would be an up to date version, it shows 190 Nm, 140 lb ft as well.
