2002 Ford Ranger 4X4 axles

Yes, they arent powered, but if the truck is moving they must spin!

Well im a little confused. Because on my chevy and my dodge my 4x4 axle does not move. I was not talking about the 2 front CV axel shaft. I was talking about the axel from the power devider (Transfor case) to the front diff.

If the actuator at the transfer case is off, the "Driveshaft" to the front differential should not move. The front axles wont either unless 4X4 is engauged, we may have missunderstood each other, Hope this clears it up. Why is yours doing something it's not supposed to?

Yes, My driveshaft is moving (from transfor case to diff) when im not engauged in 4x4. So I try it out in mud and im not engauged however when im engauged everything works good. I was talking to a friend of mine and he told me that meaby a vacum vent is dirty and it may not disengauged fully. Is this true.

There is a vent on top of the axles, but no vacuum is applied to them so I doubt it, If there is nothing wrong with the operation of your 4X4 system, I think you are trying to fix something thats not broke!
