So I found the so called "Jeep Egg" in the front bumper area. It was broken from where its suppose to attatch and has a small hole in it, about the size of a dime. I know it has something to do with vaccuum. For a temporary fix I just stuck electrical tape over the hole and shoved it back up inside the bumper area. I took a quick look at it and I couldnt see how the vaccuum lines came off of the "egg". My Jeep didnt seem to run poorly with the hole in that canister and I saw no change after I taped the hole. How crucial is that and should I replace it or just patch the hole with somethig more perminant that electrical tape?


Thanks for any advice.

 

that egg is the vacuum canister and its pretty dang important, im bettin you could throw some jb weld over it and be okay but im bettin that they aint to expensive

 

yeah I'm sure I will replace it at some point. Right now I'm more worried about making sure my trans is not going to blow up. Going to drain the oil, trans oil, replace the front and rear differential gaskets and oil.

I am not super mechanicaly inclined but I am forcing myself to learn because of the Jeep. Funny thing. I never had any real interest in mechanics until now...strange addiction.

 

If that hole was in one of the ends, thats where the fitting is supposed to be. It is broken out. That's why you don't see any vacuum lines; they are probably stuffed up into the engine compartment now (or cut off).

Buy a new cannister and properly attach the lines. It is all there for a purpose.

 

I love the location of that.. Lets put a highly breakable, very important ballon.. Inside the Bumper.

 

what happens if you dont have one?

 

My xj does not have the egg it runs just fine you will have to plug the vaccum line that runs to it for best results.

 

most vacume ***** are mainly for your ac vents an what not but them are very important fix it an there will be a diference

 

Maybe a dumb question but for the guys with aftermarket bumpers... Where do you relocate these to? Just want to see what fellas are doing!

 

theres a write up on this in the xj write up section. but other than that im building my bumper this saturday and my stock one was damaged so i took the bumper off and i just left the bottle in some open space in the engine bay for now til i think of somewhere to mount it.

 

cool thanks! i am about to do a bumper as well.

 

its the radiator dam or something...i ran mine for a while without it and didnt notice nothing

 

the "egg" in the bumper is a vacuum canister for the cruise control on a '96 and later if equipped. Not so sure about the newer ones. But if it's located in the front passenger side of the vehicle then it's definitly for the cruise.

 

No, it is a vacuum reservoir.

 

It is on any Cherokee that has A/C and/or cruise. Might be on every Cherokee.

It goes back at least to '87, possibly earlier.
