Front axle vacuum disconnect Renix
 

While I was replacing my inner fender liner on my '87 Renix, I looked over at the passenger side and noticed what looked like wires that had been chopped, hanging down near the axle.

Upon closer inspection, it appears that all 3 plastic vacuum lines have broken off at the rubber fitting that plugs into the steel vacuum lines that go up into the engine compartment.

I would rather buy a new vacuum line assembly if it is still available. If I have to go used, what years used this disconnect?

Apparently I won't have 4WD until I fix this.

Ideas?

87-94,95? I have my doubts you will find it new, shouldn't be too tough to re-plumb it though. Their is a diagram in my Sig. I'm pretty sure you have a little vacuum leak there Btw. I think in 2WD one port vets vacuum to hold the sleeve/fork over. Some like to just lock it over, which is OK. I prefer mine as designed.

I did some searching recently, looking for a spare. I couldn't find one but I was tempted to try this...

87 to 90 for sure. Maybe 91. They're all fUBAR at this point used. Here's what I have done to ALL of my NP231 equipped xJs/MJs with no ill effects. Kinda what teh factory did in mid 91.

The broken lines will create a major vacuum leak so I would recommend using rubber vacuum caps to cover all three lines or you'll have a rough idle and some hesitation on acceleration.

I discovered this too late to call my Jeep dealer. Anyone know if they are still available new?

Also, it looks like they used this arrangement 84-90.

My '92 doesn't have the vacuum module like the '87 but the '92s drive shaft does not turn while in 2WD.

Update: They are not available new from Jeep any more. O'Reilly's, Rockauto, and Quadratech doesn't have them either. I have located a '90 model at a local salvage yard. When my weather clears, I will go and see if it has one intact.
