I engage mine with both the transmission and the 4hi/4low lever in neutral. That seems to be the most reliable method on my GX.

If you can get the diff to lock/unlock (that is to say, the dashboard light will light/go dark solidly without remaining blinking continuously), then I think your timing is fine. I had to replace the entire unit on my GX470.

Does anyone know the distance the rod moves when switching the center diff between locked and unlocked? I'm surprised by how small the movement appears on my GX; I'm guessing it's less than 1 inch (maybe 1/2" or 3/4"). The rod moves smoothly between the in and out positions, but it's not very...

Yes, I did re-grease the gears, and before installing the actuator I confirmed by hand that the rod moves in and out of the transfer case smoothly.

Well, I guess that depends on what you mean by "properly". My motivation for taking this project on is that the diff lock has never locked rapidly for the entire two years that I've owned it. It would lock eventually, but only after approximately 15 flashes of the light on the dashboard. Last...

Good questions. GX has 128k miles. I believe the actuator is receiving power because I hear beeping noises in sync with the flashing diff lock light on the dash, but I guess I'm not sure where the source of that beeping is coming from. I don't know what fuse provides power to the actuator; if...

Disregard what I said about the dashboard lights; that was an unrelated problem that I cleared with an OBDII reader. The diff actuator not locking is still the problem. I guess I'll order a replacement unit.

My diff actuator on my 2006 GX470 was very slow to lock, so I decided to investigate. I pulled off the diff actuator, and it was indeed full of oil. So I ordered a new set of gaskets/o-rings. I saw an excellent YouTube video that showed how to actually disassemble the actuator, clean it out...
