4wd won't come out.. help :(
So I just purchased a my 5th yota ... 94 ext cab 3.0 v6 4x4 .
When I test drove it few days ago I did make sure 4wd worked cuz that's a must... well I drove 180 mile roundtrip today and a/t oil temp light came on like 5 effin times.. I kept pullin over letting it idle til it went out.. i know the deal.. never had it come on unless i was in 4wd and driving it hard in my other yotas.. and i kept telling myself this the whole way home... So I get home and I get out and have the g/f get in.. tell her to pull it up and front drive shaft is spinning and axles moving too...hmm at 70mph no wonder it was coming on!! any ideas why it's stuck in? Any help appreciated.. thanks!

It's an auto with auto locking hubs and auto 4wd shift.... I need to get it out of 4wd asap
The light does come on when u select 4hi or 4lo and goes off when you shift back to 2hi.. but it's still staying in 4wd??

driveshaft shouldnt move in 2wd, the front axles will though. The ADD trucks don't have "hubs" they just have flanged that lock everything together....

What jay said. So my point was that the axles won't tell you anything, but the drive shaft will. Is the 4wd light in the diff or the t-case. Wherever it is, this part must be working, right?

I believe the 4wd indicator for the dash light is the white plug on the front of the diff.. and yes it goes off in 2wd.. comes on in 4wd.
why is my front driveshaft moving in 2wd?

Jack the truck up. Put the tcase is 4 and the tranny in N. Spin the driveshaft by hand. If the drivers side axle spins in the front, the diff is not disengaging.

even if your front diff isn't disengaging, it shouldn't cause the transmission oil to heat up that hot...
My 90 Xtra cab has manual hubs, and I never EVER unlock them (has the non-add diff so the front drive shaft will spin if the hubs are locked in). I drove many many trips of >2 hours at sustained speeds of 70+ MPH without a single hiccup. I'd say your problem has to be in the t-case/transmission, because no matter if the front is disengaging or not, it shouldn't be heating up the transmission fluid...

Good call, have you checked the transmission and t-case fluid levels?
Most guys will recomend you install an aux a/t cooler. Those autotragics don't like to get hot

more than likely its just the linkage and nothing else. i used to have climb under and put it in 4wd and back out by myself. they get alot of slop in and bind up before they can disengage the transfer case. Id verify the position of the transfer case selector before messing with anything else first.

ok the trans fluid is full and clean as it could ever be.. that
s not the problem.... i mean you could pour it from a bottle into your hand and itd be the same.
It's raining here a lil and i just drove truck and the rear tires are spinning in the rain like they should be.. so i was thinking if it's locked in 4wd they wouldn't spin right?
i also read alot of people who have ADD setups on jeeps and ford's that the front driveshaft always spins cuz of the ADD ( or whatever the name they have for each brand )
on the toyota setup some people also told me that the front driveshaft always spins to... but the way the ADD works from what i understand is the pass side cv axle always moves.. and when 4wd is engaged it locks the drivers side...
who's right and who's wrong??

see this was my first approach... i even unhooked it and tried to move it back further... it seems to be coming back as far as it will go.. truck has 3" body lift so this was my first thought.

not sure about add.
can you tell if you put the truck in 4wd manually and then drive? that way you'll be able to see whether its just the add making the shaft spin and the somewhere else.

I mean the shaft is spinning in 2wd 4hi 4lo.. so putting it in manually i don't think is going to get me anywhere.... the whole point of ADD is to be able to shift in to 4wd while moving so it kinda makes sense to have the shaft moving.... i asked some jeep guys and they said there's always spins on the jeep disco front end which is just like the toyota ADD setup.. I've never had ADD toyota .. always had manual hubs or auto hubs.... for all i know this could be normal.
