    As long as you aren't spinning wheels or driving at highway speeds you should be fine engaging/disengaging them while moving.

    But if you spin out & come to a stop, do NOT engage if a wheel is still spinning. Hold foot on brake to stop wheels then engage it.

    both the power divider/inter axle lock and the wheel locks/ full lockers can be engaged at any speed as long as the tires are rolling n not spinning out.

    Some axle (full lockers) will not engage in the high side of the transmission, and, if engaged while in the low side sill disengage automatically when shifting into the high side. At least the 2005 Pete that I drove was like that.
