A good explanation of shifting in and out of 4 wheel drive?

 

You can shift back and forth between 2hi and 4hi while it's moving, to go in and out of 4x4 low you need to be stopped with the transmission in neutral.

 

Here's how the factory suggests you shift the transfer case.

"To engage, shift the transfer case lever from 2H to 4H while the vehicle is moving at any legal speed". I LET OFF THE GAS, THROW THE LEVER, TAP THE GAS AND LET OFF.

4L position: " To engage, slow the vehicle to 2-3 MPH , shift the transmission to Neutral, then shift the transfer lever to the right and pull firmly rearward to 4L".

TO SHIFT OUT OF 4L, SHIFT THE TRANSMISSION INTO NEUTRAL WITH THE VEHICLE STOPPED, SHIFT THE TRANSFER CASE LEVER TO 2H, THEN THE TRANS TO D IF YOU HAVE AN AUTOMATIC, OR INTO FIRST GEAR WITH A MANUAL, AND CONTINUE ON.

 

Yes it helps to be coasting at a very low speed (like not even registering on the speedometer) in neutral to get into 4L. 4Hi and 2H is just a pull of the lever away. I let off the gas pedal during the shift to unload the drive train but that's just me.
