The breather tube port is the weak point. That's where water gets in and never leaves. I had to replace mine, very rusted but the motor still worked. The contact points that allow the actuator motor to sense it's position can become messed up and prevent it from switching into/out of 4wd. The preventative measure is to tip tie / hose clamp the breather tube port.

There also people out there saying it could seize if its not used alot. I at least test it once a week just to check. Others say once a month is good.

I put a bead of silicone on the outside as well and also a little dielectric grease on the connector.

Thank for the video. Gonna be doing this 8n a few weeks

My 2000 tundra has the same electronic actuator and it’s the original even after dozens of trips through the rivers of Azusa. Another option if yours goes out you can bang on it and sometimes it will engage four-wheel-drive if you’re on the trail.

Like the video. 2016 Hilux in South Africa have the same problem. Will have to install my doff breathers higher for water

Thanks bro..good info...it is my mission tm morning to do what you just did..

All/most of the new 4runners made in Japan have the manual transfer cases. why not the Tacomas? on a side note, when fording deep water/mud, always keep the clutch engaged before, during and after.... this prevents slippage.

Yup, moisture in there tends to be a nightmare for some, usually moisture c/m goes in through the vent. As you can tell the gasket is good since it withheld the water inside. Non ADD front diff, manual j case gang!!! Cheers bro!

Well done

FYI, that is the actuator for the diff. The actual 4wd actuator is on the back of the transfer case. I had to replace mine last week and Toyota wants $1100 for it🤑

Nobody's surprised your dashboard looks like a Christmas tree if theve seen you videos. 😂

my 2019 taco got stuck in 4lo about 250 miles from a toyota dealership and about 80 miles from a shade tree mechanic.. Had to pull the from actuator power then actuator to manually force it in to 2wd to drive it out.. sucked.. I took it to dealership and they ended up replacing the entire xfer case etc.. luckily it was under warranty still.

My vacuum line is super short and isn’t connected to anything. Could this be causing the issue?

The right lights lit up!!!

So why do some have that and some don't, mine has it and it's a 2003 Hilux why not just have that in the transfer system.?

Boy did you hit home with this one. My 2020 PRO has been a nightmare since day one with engaging 4wd. Extremely unreliable. Very frustrating. Its my transfer case actuator that i have problems with.

Can you fix repair old actuator

Probably should've linked the actuator you used in the description....

Did I miss link to buy axchewatet

Real world solutions to real world problems! :)

That new 2023 Taco is basically a Prius with a pickup truck bed.

When I saw the descrition I thought you where going to snow how to install a 60 frontend in a Tacoma.🤣

Wait I thought you where supposed to be moving when shifting into 4X4 High?

Bring back manual, front locking hubs.

How had this held up for ya? Just bought the same actuator as you

C’mon man, get a jack stand under that truck?

glad it was just the actuator

My 06 has all of them alarms on dash

Scan your truck and check and clear your fault codes.

Frist post 🎉🎉

All I saw was 14mpg😮, on 35s? Im jelly😢

The fix? Manual hubs and weld a nut between the fork and actuator :p

What are the two major ingredients that you don't want to expose an EV vehicle too??? Dirt and water????

Can a Taco be designed from the Factory that meets Taco Lovers Requirements??? Not Joe Bidens.
