How can I Stop my Suburban 1500 from going 4WD?
How can I Stop my Suburban 1500 from going 4WD? Only way to stop it was to stop and restart the motor. Shift into neutral, then push one of the 4WD buttons, then the 2WD button, which you could then hear and feel the transfer case shift back to 2WD. Then it would drive fine until the next time it would do it. About every 50 to 100 miles it does this. Can a suburban go from 2 wheel drive to 4WD? Vehicle shifts without warning from 2 wheel drive to 4WD. Currently can not get it out of 4WD....
