      I have a 1999 explorer XLT 4.0 with the standard 4wd features. My question is tho, when i shift to 4wd lo does that lock the back or front wheels? also does it lock the diff or do the hubs lock. I am aware that something engages because when i put it in neutral to shift to lo i hear the electronic whhhhhhiiiiiirrrring for a second. Just trying to fully understand the 4x4 features.

      When the transfer case is in 4low, power is routed to both the front and rear drive shafts. When in two wheel drive power is only routed to the rear axle. High range sends power to both axles with no gear reduction. Low range has a planetary gear set to achieve a gear reduction for more power/control in offroad situations. Your explorer doesn't have locking hubs. The electric shift motor is on the back of the transfer case and moves the shift forks inside the transfer case.
