Re: 2001 4x4 question

My '98 Sub has "auto" 4wd. I think this is pre "autotrac" but may work the same.

In "auto" 4wd there are 2 sensors that detect a difference in speed from the front to the rear. When that happens the tx case will clutch into 4wd (not slam). So, in "auto" if all 4 wheels are turning the same speed you're still in 2wd (kind of). When you put it in 4hi or 4lo things will react as "Sonny01" has described as it is now locked into 4wd.

Kind of lame but I hope it helps you to understand it better....Steve
