I have a 2005 MAZDA B 4000 4x4, 3.0 liter. When I shift into 4x4 high there is a hard snap and it feels as though you run over a deep crack in the road. This happens approximately every 10 seconds or so. When I shift back to 4x2 it happens one last time. If anyone can point me in the right direction I would greatly appreciate it, Thank-you.

Sounds like you may have broke a tooth on the ring or pinion on the front differential. You'll have to remove the cover to inspect inside.

Just a comment to add: I don't know the exact engineering of this 4X4. Some are undifferentiated (fronts) and really don't like being used at any higher speeds OR if not very slippery.

Out of a couple hundred only have owned two 4X4s both locked the front and were RWD when not engaged and even just wet road they would react with wild symptoms if not put back to two wheel drive. I used the two to plow snow which is slow speed and duh plain 2WD won't push 10 tons of snow! IMO if not in ice, snow, mud or stuck if the vehicle has a choice it should only be in 2WD mode or you probably broke something as said,

BTW - never snows in New England! Ha!
