Hey guys, can any one give me a "play by play" of how that vaccum shift actualy works? What sends the vaccum signal to enable it to shift?

I cant seem to find much on line or I am not searching properly, any advise would be great.

Thanks,
JJ.

 

I would get TJ shafts and Warn, I think Yukon gear also makes a seal kit to eliminate the vacuum disconnect. You get the bigger U joints to boot. It is not hard to do.

 

tj shafts fit the dana 30 in a yj??? and there's no disconnect on the pass side?
must add this to my wish list!
