4Hi to 4Lo question

[Black94Prado]

Alright I've got another question... The kzj78 has push button 4h and hub lock rightttttt. So when I lock the hubs and engage 4hi it's in 4hi, duh. But here's my question, today I was out exploring some logging roads and put it in 4lo while it was in 4hi. Is that bad? What does it do? What I mean is I had the hub lock button pushed in, and the 4H button pushed in. I then put it in neutral and shifted the transfer case into 4lo without disengaging the 4H button. It went into 4lo but.... what about the button?? Does 4H need to be disengaged or what? Like Can I just keep the 4H button pushed in or is that somehow bad for the transfer case or transmission? Thanks again folks...

You have to keep the 4h button in, to get to 4low. You did it perfectly right!

4h gets you to 4wd, then 4low gets you to the hard core.

^^^ The 4H button operates a vacuum diaphragm that engages the front driveshaft. The transfer case lever just shifts between high and low range. Both have to be engaged to be in 4L.

Wow. Here I was thinking I had a transfer case issue because I couldn't properly have it in 4L........... I feel like a fool! haha. But jokes aside thank you, this is the single most valuable piece of information I've received about the cruiser.... simple as it may be.
