4wd wont engage

[chad27579]

Hi All,

I went out today and noticed that the 2000 luxy didnt have any drive from the front wheels. The light came on saying 4wd was engaged but it wasnt working. I have Vaccum sucking in all lines, i can hear the ADD motor but it just wont lock in. Any suggestions?

ive heard of this happening before where water has got into the add system causing it to corrode and not engage properly.
dissasembly may be required

cheers Troy

had that problem with an earlier hilux a few years ago and found out that when it went for a service the mechanic put the vacuum lines on the wrong way. not sure now what he did but i took one off and changed it around and it engaged. i think it was the something to do with the aircon line. not sure but that was what it was , wrong vacuum hose on the wrong pipe. try that.
