From A.D.D To Manual Hubs???
Hi everybody, I have a 1990 Toyota 4runner 5spd and having problems with my 4wd. It wont engage and I took it to a tranny shop and he figured it would be the actuator on the front diff, which is a couple hundred bucks. Some friends suggested putting manual hubs to eliminate all the problems with the A.D.D. The thing is I talked to 3 people and got 3 different answers on how to change them. One person said to go to the junk yard and get stock aisan hubs of toyota and they should just bolt on and work, another person said i need hubs and a spindle conversion kit and another person said i need axles , hubs, spindle kits. So if i get some manual hubs from a toyota what do i need to do to switch from A.D.D to Manual Hubs. please help snow is here where im at,.. Thanks

Well, if you can get it to lock, then you can apply vacuum and loop the vac lines. So it keeps a vacuum.
Unless the actuator is broken. Then go get a used halfshaft and replace it.

Everything you wanted to know, but were afraid to ask: http://www.off-road.com/trucks4x4/ar....jsp?id=399612
Bottom of the article has all the how-to on locking the actuator. It's a simple job. As was mentioned before, check wabfab's site for a set of Aisins. Remove the old flanges (very simple) and bolt the new hubs into place. Might take you 45 minutes or so.

If you get around to installing some manual hubs later...

no the light doesn't come on, but the transfer case locks in when i put iti in 4wd, the guy at the tranny shop tested the vacuum and said when in 4wd it has vacuum going into the actuator but not out, so he said that the it had vacuum going to the actuator and the t-case was working so said it was the actuator

This goes back to my post. You cannot fix a problem with the ADD actuator on the DIFF, by replacing the drive flanges with HUBS. They are two different systems.
Either 1. replace the actuator, 2. lock it in all the time (people have used hose clamps, but I do not recommend that) 3. replace the diff with a non-add setup and do a manual hub swap or 4. Buy a Prius

So if you know its the actuator, you can fix it. Right?
