Does anyone have the vacuum specs for the 4x4 system? I have checked the solenoids and hoses to the shift cyl. at the diff. and all seems ok, just seems like it has weak supply vac. to the the solenoids. If i had the specs on how much vac. i should have i could go from there. Can anyone help.?

 

There should be about 10 in Hg (25A cm Hg) of vacuum.
