Help, I'm stuck in 4WD

[orangeblast22]

My 2006 Sports Edition V6 is stuck in 4WD. I recently/accidentally engaged the center differential function (the orange 4WD icon with the X in the middle appeared on my dash). Once I got myself out of that, I noticed my 4WD would not switch to 2WD no matter what I do to the knob.

Any ideas on how to fix this?

Put it neutral then shift the knob to 2WD , then roll it slowly back and forth between D and reverse. Could take a while

If I had issues switching between 2WD and 4WD, I would be more than happy if it failed in AWD mode if the center diff lock still worked.

Even if it never switches back, its perfectly fine to leave it as it is.

With the center unlocked, it's basically in AWD mode and perfectly fine to drive on roads.

... up to 55 miles per hour. don't do this.

read the paper that is on your driver's side sun visor and keep trying to cycle it out of 4WD (it's not AWD, ever).

Thats false, brother. The 4th gen, with the center dif unlocked is absolutely AWD. Thats one big reason I like the 4th gen's 4wd system over the 5th gens; a torsen center diff! Generally speaking you could go any speed in 4wd in the 4th gen with the center dif unlocked, and do any type of driving on any type of surface.

The 5th gen, you can technically drive any speed as well, but you're limited to turns at about 30-35+mph. Any turns slower than that misalign the front and rear wheels enough that it causes binding in the diffs due to differing wheel speeds.

I learned the hard way that part time 4wd in the 5th gen doesn't mean you can switch between 2 and 4hi whenever like I was used to in the 4th gen. And that 55mph number you're thinking of is engaging the 4wd system, and i think it's 60mph. If you try to engage it above 60, the system just beeps at you. You slow to 59, engage it, and then continue on your merry way.

To OP, yeah, try shifting into neutral and tapping the brake a few times, or rolling forward a bit. I'd even take it on a drive and leave the switch in 2hi and wait for it to switch. I once couldn't get 4lo to engage and I kept rapidly swtiching it between 4hi and lo, and then the transfer case finally broke free and engaged.

What “simple” said! You just have to shift between H2 and H4 at speeds below 60mph.

Also, I believe that the 5th Gen Limiteds have the Torsen diff.

This is correct. I don't think many users understand the difference between the transfer cases between different generations of 4runners and the models within that generation. 4th gens all have torsens with the V6 being able to select 2wd and 4wd unlocked. If OP is stuck in 4wd unlocked there is no speed limit in which he can drive in this mode.

4wd binding

Did you have any issues with vibration or drive shaft issues after the 4wd binded?

if you are really stuck in 4wd only[green 4wd sign on dash], and you try to remove it from 4wd by turning the knob to 2wd, then the amber and orange signs will be blinking on your dash,

there are several methods to force it to disengage.

1. drive on uneven surface/road, about 200 700ft, should knock it loose

2. try disengaging why you are making a slight turn
3. go to a dirt road, lock the differential, then unlock, then try switching back to 2wd.

4. try engaging the neutral gear while attempting to switch into 2wd

5. put the car in reverse and try disengaging

6. last last option, get the wheels off the ground, use a mallet on the 4wd actuator, try in neutral and drive

That speed limit only has to do with mode switching (2WD to 4), once you are in 4 you are good to operate as normal.

It's 100% AWD (mechanical limited slip like an AWD Audi) with the center diff unlocked as all 4th gen 4Runners use a Torsen center diff.

Yup, the 5th Gen Limited was the only trim level to keep the Torsen, which is the same as the GX and Land Cruiser.

The V6 4th gen does have the ability to drive in 2WD in addition to the rest of the other modes, which is pretty cool and unique. The 4th really is my favorite generation of 4Runner.

Mine has been "stuck" in 4WD from the factory. The V8 has no 2WD option for whatever reason. There's no downside, but you do probably want to get it unstuck in case you want to use the low range sometime. the 4WD V6 has the same system, but with an ADD (Automatic Differential Disconnect) in the front.

A few things to try:

• Drive around for a while to make sure everything is warmed up
• Try shifting with the center diff lock on or off, while driving below 55mph
• Come to a stop, and with your foot on the brake shift to neutral then try to shift to 2WD. If it doesn't shift right away, try letting your foot off the brake to roll slightly
• As someone else mentioned, try switching while driving slowly and turning slightly right or left
• Try reversing a little, then doing the procedure to switch at a stop in neutral
• If all the fails, some people have had success loosening the bolts on the actuator cover and tapping on it (the cover?) with a wrench
• You could try to go to 4WD Low then back to Hi, but if it gets stuck inLlow that would be bad

Annnndddd.... I'm still stuck.

Last night I pulled my battery to finish up some work on my aftermarket HU install. Started her back up only to find the green 4WD icon on, an orange 4WD icon with an X in the middle, and my VSC off.

I read online... Followed instructions in the driver's side sun shade... Drove around my neighborhood an hour...drove back and forth in my drive way like a mad man for an hour...and nothing.

Turned it on this morning, still there.

Feels scary to drive because it's so tight in the turns. I don't feel safe, but it's my daily driver and I have to resolve this.

I also don't understand, why does it do this when I pull the battery? I've pulled the battery several times before but it's doing this now... Don't get it.

 

[Swipter]

Well, the advantage to this is, after going back and forth in the driveway that long, if the neighbors didn't think you were crazy, now they know you are.

Life is fun.

Personally I'd stop using it as a daily driver until you figure it all out. Sounds like the center differential is now locked and on dry pavement that's a big no-no. If there is no other option you might just have to bring it into the shop to resolve if you can't yourself. You are putting a lot of stress on your drivetrain right now.

I'm not sure the center differential is locked because if I press the button, the orange 4wd symbol blinks and I hear a beeping sound. I think this is the proceaa to go about engaging a locked differential.

If this is the process to lock the center differential, then what is mode is my car currently in? Plus I was doing 70 on the freeway last night with these issues and I didn't have any problems except for the tight turning. And I cannot afford to not drive my car as it's my daily driver.

 

[BackOff]

You said you put in new radio?
Did you forget to plug the 4wd dial back in?

I turned the switch one time i had the dash apart and the 4runner did not like it...don't turn the 4wd dial when its unplugged.

Why do you think the turning is tight? That's a locked center differential son.

 

[orangeblast22]

So what would pressing the Lock Center Differential button do then at this point?
