Unhooked vacuum line

[Renoenvy08]

The blue vacuum line that runs to my transfer case is not hooked up, I've looked but can't see any loose lines that it might connect to, it goes into 4 wheel with no problems but it's bugging me that it's just flapping in the breeze by my front shock mount

Does it have a little fitting on the end?  I don't remember the color offhand (I deleted all that) but there is supposed to be a loose line, vent with a check valve on it that isn't seemingly connected to anything...except the check valve.

Yes there is a check valve. Thanks

Not supposed to be hooked up. It's a vent for that crappy CAD system. 

 

I would ditch all that crap. 

 

Here's why:

 

CAD STINKS

 

 

The big issue is that the CAD system only fails when you need it the most.

 

Kinda like when you don't realize your wiper blades need replacing until it rains....

 

I know somebody’s system works and he advocates keeping it stock, but my exposure to the failures is probably hundreds of times greater than his, as a result of being Service Manager at a Jeep dealership from 1980 through 1992, and being a current XJ and MJ owner. 

 

CAD stinks. Every Jeep I work on with it, I eliminate it. Guess what I find in the process?  25 year old busted vacuum lines, bloated vacuum line connectors, bad vacuum reservoirs and piping, bad transfer case vacuum switches. In other words, had the person gotten into a sticky situation and needed 4WD, they would have been screwed!!!

 

That's the tip of the iceberg. The factory went through 3 revisions of the shift fork also. The fork issue is non-existent if you just slide it over and leave it.
