I found this underneath my jeep on passenger its got 3 plastic tubes in different colors that run up to what looks like brake lines and on the other end is a rubber piece with 2 holes that plug in to what may look a a big sensor or vacuum thing. Its broken can any one tell me what it is and what it does?

 

vacuum disco front axle.

 

your front axle is engaged by vacuum if thats broke you dont have 4wd. Its not a real sought after axle. Swap it out with a solid axle shaft and move on lol

 

its a solid axle and i already knew my 4wheel dont work what does it do specifically?

 

Or you could just replace the lines to fix the vaccine leak??? Lol I agree with up grade but it's not really really broken yet!!! So I say just replace the lines! Unless you got the $$ to up grade

 

have no o money for upgrade having hard enough time getting the thing to pass smog
