Outer Limits 4x4 Board

Hey everyone ,,Im a new member to the site and iv got a question about my mwb cruiser i recently bought.

My Question Is : Is it alright to Drive the car with the hubs locked in and not activating 4wd by pressing the H4 button, would it harm anything if this happened?
just wondering as i accidently left the hubs locked in whilst travelling home a short distance after wheeling.

thanks

yes its ok, the only downside is a bit of noise and slightly increased fuel use.
