'92 4Runner 4X4 problems
I picked up a '92 4Runner in February with a new crate motor in it. But my 4 wheel drive won't engage. It does not make any noise and when I put it in 4 wheel low it creeps along but the light does not come on and it deffinately is not in 4 wheel drive. Someone suggested a vacum leak but I don't know where to begin to look. I have been puttin git off but hunting season is fast approaching and not having 4 wheel drive is simply not an option. Help!

Thanx. Everything is factory at this point. I have an appointment to take it in on Friday for the steering recall and I'll have them figure out what the problem is. Then I can talk to my friends about getting it fixed. I wish I had my '93 4Runner back.

alright well if you want help (in the future too) we need details on your truck. There are several different types of hubs, and t-cases, and the fixes/common problems for each are different

I am pretty vehicle illiterate. How do I find out this information? It's a truck, you put in gas and change the oil and it goes. It's a 5 speed with the 3.0 V6. Everything is stock to the best of my knowlege. I have been waiting to get money from the settlement to start fixing it up.

it can be manual hub, auto hub, or add. Manual hubs need to be manually locked (turned). add's comonly dont work due to vacuum leaks. If you dont feel comfotable by all means take it to a shop. If you're willing to atleast give it a look figure out what type of hubs and get back to us.

Inncorrect. It CANT be Auto hubs, since they discoutinued that in 1989. It CAN be ADD Hubs, which is just a drive flange on the spindle. Unless it was converted to manual hubs, this is what you have. Either way, the ADD diff should still be there. That is Vacuum controlled. Could be a few things, such as the Actuator, the VSV's for the ADD, or a vaccuum leak, or something much more complicated. Sounds like you need to get a vaccuum tester and se if you can pinpoint what is keeping the diff from recieving vaccuum pressure.

It probably has ADD and my first quess is they are not working. I would suggest just putting manual hubs on it and not worry about trying to fix your ADD system.

yeah, you need to take a look at the vacuum lines and figure it out. if you do a search theres some threads with info on how to check out all the add stuff.
