need help! 4wd prob, hubs not locking.
ok guys here is the scoop. i need help with some vaccum hoses. i have a 98 4x4. i know i have some vaccum leaks. underneath the passenger headlight, about the inner fender, there is a part called vaccum selenoid. it has 3 wires going to it and 3 things for vaccum hoses. mine has one and it goes to a hose on the frame. where do the other 2 go? i assume at least one goes to a hub because my 4wd does not lock in. but where does the other one go? I looked at my dads 99 4x4 but was confused cuz mine has a vaccum resevoir on the inner fender whereas his did not. so if some1 could help me i would appreciate it.
edit: the front d/s is spinning so that means all is well in the transfer case correct.
