Engaging the Center Differential and 4Lo Periodically? (2 Viewers)

[GXNORI]

Hi all,

I'm new to 4WD ownership, and I heard it's a good idea to engage the center diff and 4Lo periodically to make sure they continue to function properly in the long run. Now my question is how often should this be done? Also, my GX is mainly a suburbia crawler and there's really no loose terrain near me. Is it possible to safely exercise the center diff and 4Lo on dry pavement?

You can engage 4Lo and lock your center or rear differential but I wouldn't advise driving on pavement when engaged. There's really no need to engage if you're never going to use.

Engagement usually involves steep ascent or descent on non-pavement surfaces. Otherwise, just drive in 4Hi all the time.
