The replacement process replacing vacuum lines requires a methodical approach Remove old vacuum lines with your tools in hand, follow. Without going into much detail, the system works under vacuum that allows the front hub engage to 4 wheel drive by a part called the actuator
My vacuum lines are completely dry rotted, and im trying to replace them but cant find out the exact id size The closest i found at the auto parts store is 7/32 id Is this the correct size? It also activates the vacuum motor and switches vacuum to the esof hubs which lets them engage when in the auto position
So if you hubs are gummed up or you have a vacuum leak or malfunction your hubs.
Four wheel drive vacuum leak repair on a slick, snowy day, i flip the electronic shift on the fly, or esof, to 4wd high and my heater switches from heat to defrost. It has to seal tight enough to hold a little over 10 of vacuum It can be done but you are trading time (to repair/seal) for money (to just buy a new one and install it) If you don't have a vacuum tester i would.
I replaced my vacuum lines and they are in good condition, but it still does not want to engage the front axle So i then pulled the vacuum lines off and felt for the suction out of one hoses.
