Specs. Standard 22re, auto locking hubs and ADD system. If I put it in 4hi or 4low I hear the click from the dash but not dash light. The driveshaft spins but the front wheels do not engage at all. I believe it to be vacuum line related but can't seem to find a decent pic of what I am looking for under the hood. Toys are all new to me except for watching Mike B. beat his through the curse  Any troubleshooting tips with pics would be great. Going to take a crack at it tomorrow. thanks |

Someone correct me if i'm wrong, i'm not a Toy guy but you should be able to look right on the front diff and follow the lines from there. Could also be the actuator itself.

ooops , try this again www.4x4wire.com/toyota/tech/add/2 of my friends had trouble with those systems taking a long time for the 4wd to engage and it was restriction I'm pretty sure . My 2 cents , I'd do like the article and bypass it , the whole time I drove my toyota on the road the hubs never seen the free position . Your truck doesn't have automatic hubs , just drive flanges (slugs) so most of the stuff up front is turning all the time anyways . If I had 1-2 mpg extra in one hand and a reliable 4wd system in the other (especially coming into winter) I'd be going for the 4wd . |

so if I follow that article and pertinently but the fork in the locked position what exactly is happening up front? It still isn't in 4x4 until I shift the transfer case.. correct? So essentially it would be like a jeep tj? In that everything up front would turn all the time?

Thanks for the info. I will just lock that fork in place and get rid of all that vacuum line crap. Now I just need a place near Halifax to do it (no garage at home  ) |

Ok.. so Mike and I fixed this in about an hour. Too easy. Dropped the skid, popped off the actuator, clamped the fork over (btw that was the problem the fork was very stiff..), little RTV and 4 bolts later it was done. Then I pulled the vacuum lines back to the solenoid area and capped them.. also capped the 2 on the actuator. On a different note we fixed the steering box leak. Was basically going through a bottle of fluid every couple days. Though the box or pump was gone. Turns out it was the relief fitting that rusted out. So we replaced it with a spare Mike had and all is well. Cost of both repairs 30 cent hose clamp b/c neither of us had one  Thanks again for the info and help in this thread. And of course a huge thanks to Mike for his help and shop. |

Finally found the thread Yeah, the steering box fix turned out to be real simple, and the ADD thing was a breeze. Worst thing was no diff oil to top it back up again, so its a little dry right now. It'll help the RTV cure anyway Thanks for the link on fixing the ADD thing too, that system is new to me. I'm used to manual hubs. And Rob will be too, because I'm swapping in a set from my parts truck in the spring |

No problem fellas , I know some of the dodge front ends had trouble with their axle disconnect as well . I seen guys wedging all kinds of shit in there to keep the coupler in place , most people just remove the whole works and replace it with the one piece axle , neither of which would be as quick or easy as the one you guys just done . I know if I had a Toyota with that system I'd do that right from the get go .
