So I was under my 2012 JKU today and noticed I had a vacuum line disconnected on the brake vacuum assist/pump on the front frame rail behind my Hanson bumper. I go to push the vacuum hose back onto the nipple it popped off of. When I pushed, the nipple broke off. Now there is no longer anything for the hose to attach to. Tried to find a replacement vacuum assist/pump online with no luck. Does anyone have any suggestions? I really don't know what issues will arise if the vacuum hose is left unattached. I also don't want to spend alot of money if that vacuum pump piece is expensive.


The arrow in the picture below points to the nipple that broke off.

 

It's a 2012. Start with the warranty.

If that doesn't work, find a length of a smaller diameter tube, whether brass or plastic, that you can epoxy inside the opening, then add another tube outside of that to match up with the inner diameter of the vacuum tube.

 

That hose (the small one) is an exhaust. the only reason the hose is there is because of the location of the pump. You should notice the other end of the hose is attached to nothing.

The only danger of the broken nipple (and the primary reason I'm replying to your question is the chance to write the words "broken nipple") is that you may get water inside the vacuum assist pump.

I had to relocate the pump to mount a winch, so mine is now up in the engine compartment. The instructions with the relo kit said that the exhaust hose was not necessary, in that mounting)

I see you have several choices:

1) do nothing, and hope no water gets in there (not a very good idea).

2) go to the dealer, and tell them you have a broken nipple ( ) and get your nipple replaced under warranty.

3) relocate the pump. I used the ORFab relo kit. I wouldn't do this unless you are going to mount a winch or something. Why should you pay to remedy Jeep's giving you a broken nipple?

If you do relocate the pump, the only down side is that you definitely can hear it when it comes on. However, that seems to be very rare, and only for about 10 seconds. I suspect that noise issue is why Jeep chose to put it down where they did.

Thanks for the info guys. I guess I can check with the dealership and see what they say. I just don't want them to keep my Jeep forever to replace it. That is good to know that the hose that is disconnected won't affect the performance of my brakes. Thanks again.

 

Removing/replacing that part is probably about a 30 minute job including R/R the front bumper. However, I would not expect that to be a part the dealer would have in stock. So it would probably be one trip tot he dealer for them to see it, and another for them to replace it.

So the dealer checked it out, and said it won't be under warranty since I have an aftermarket bumper and winch installed by another business, mounted on my JKU. They also said it would be $300 to replace the part w/labor. I can't believe how the dealership service departments always try to screw over the customer. They didn't even mention relocating the assembly to save me that $300 fee. So I guess I will be purchasing the relocation kit, and doing it myself once it comes in. Thanks for all the info everyone.

 

I'm pretty sure they have to prove that your bumper and winch broke the pump to refuse replacing it. Don't give up.

 

Can you try a different dealership?

Given the good info that you got, that this is just an exhaust port, I'd be tempted to just epoxy a smaller diameter tube in the reservoir outlet and flare out the end so that it will hold the rubber tube (or you could glue that to the tube, too). For $300, it seems like a reasonable alternative.

 

Why does a JKU need a vacuum pump unless it's a diesel ?
Is there also a vacuum reservoir ?
Did the bumper installer break the nipple ?

Glad I found this thread. I was mounting a rugged ridge winch plate on my 2016 JKU with 10th Anniversary bumper and snapped off the nipple. Intried supergluing it but that snapped off too. I stopped my install and came to the forum. I was glad to hear that it wasn't a serious issue and completed the install. Now the pump is tightly secured behind the bumper and over the steel skid plate. It is positioned on its side with the broken nipple port on the bottom. Now I am debating whether it is worth the effort to go back in and either relocate it or do some kind of epoxy fix to it. I also thought about just leaving it there and buying a new one and relocating the new one. After looking up the price of a new one ($250), I am ruling out that option. The only concern I have is whether water will get in it and what would the consequence be. I think that might not be much of a concern if it is truly an exhaust port and it is at the bottom of its current mounting position and is protected by bumper and skid plate. Do you have sny thoughts on this?
