    This, do you still have your foot on the gas when you take it out? If so take your foot off the gas.

    Mine does it, it seems normal to me, everything I have ever owned that was four wheel drive made a similar noise.

    If it is just one knock (I call it a 'thump') then okay...

    Running the front drive shaft, differential, ADD, axles, tires with engine torque is a major deal... so expect something when you go in or out of 4 wheel drive.

    It won't make the noise if there is no tension in the drivetrain. Disengage while you are coasting on flat ground and it should be silent; maybe just a small "click."

    Mine used to do the same but since I've been going in and out of 4wd a lot recently driving in the snow it's stopped doing it.

    As others have said, if it's a single clunk it's no problem.

    Let it coast for a sec before you engage or disengage. Clunk means be patient with it.

    Umm??? Isn't it the same sound as when you first asked? Hasn't everyone told you it is normal and some ways to perhaps lessen the sound?
    Did you not first shift from L4 to H4 at a stop and in Neutral (the standard way), then go from H4 to H2 while moving?
