That's a good explanation of the ADD (Automatic disconnecting differential) if you're interested, I was positive I had heard that the system used in the 2024 was slightly different than the previous gen but I'm not finding it googling. I think it was mentioned in one of the ealry release videos or Hawaii with Sheldon. It doesn't really matter but the ADD is a somewhat commone issue with the Tacoma. Basically, if something goes wrong with 4WD engagement or disengagement this is one of the leading causes.
Manufacturers all handle this differently, that is the move from manual locking hubs to electronic 4WD systems.
Tacoma's and Toyota 4WD vehicles have a history of struggling to engage or disengage 4WD, especially 4L the actuator in the ADD is the typical problem:
"There are two switches that must be in the closed position for the 4WD light to come on. The first switch is controlled by the position of the transfer case shift lever. The second light is on the ADD actuator and it turns on after the sleeve has moved into the right (locked) position."
"When the transfer case gear shift is shifted into 4WD, the ADD system is actuated by the operation of the ADD solenoids located under the hood on the passenger side wheelwell."
That's what I thought had changed, I remember someone noticing that isn't there anymore or looks different on the 2024. It could have been a limited which has a FT 4WD system and thus wouldn't have the ADD unit.
I would want to ask Sheldon to talk about this component specifically. Was it changed? If so, why or why not?
I disagree with the "fuse" aspect and I still haven't watched the video. I mean I get what they're saying but it sounds a little like a cop out to a system that is known to cause problems with Toyota. If I'm stranded because the ADD broke I don't know if I care that it saved another component. What's the stress load of the ADD breaking vs. a diff or something else? Those are Sheldon questions I guess.
For what it's worth Jeep and Bronco use a FAD, front axle disconnect. There is some decent articles out there about the differences and how the disconnect is handled.
