Bruce, you and jwaller are correct. No air= No front axle engagement.

Awesome!!! Now I know who to call when I break down on 270! lol I must say that wrecker looks right at home working like that!

I had no idea that the sprag ONLY functions when the air system is charged. I looked into a bit and JWALLER is definitely correct...no air and the sprag stays in a neutral position (neither forward nor reverse). Still, that was a surprise. You learn something new each day!

ya thats why the installation of an airshift switch like the deuce's have is pretty useful on the 5T trucks (there is a very hard to find MWO for it). you can have it only when you want it. saves possible damage on the sprag too when you forget to put it in R when rolling backwards.

Wouldn't having the air hooked up, only matter if you were "flat" towing it. Otherwise, wouldn't the front tires just spin in the air?

Yeah, they will spin in the air all right. Done it!
