what is the difference between 4 wheel drive....
i am looking at 2 different 2009 f-150s. one has 4 wheel drive mechanical shift, and one has shift on the fly. does anyone know what the difference is? can you shift from 2 wheel to 4 wheel while moving, with a mechanical shift 4 wheel drive?
thanks

As long as all four wheels are rotating at the same speed( ie: you are not spinning at time of engagment- let go accelerator for the moment of shift) it will work seemlessly, as previous poster stated with electronic or manual shifter.

the hubs on the manual system must already be locked in to be able to shift on the fly. the electronic system does not.

just make sure all tires are rotating the SAME speed. and speed doesnt matter. i have shifted my 05 and 09 into 4-hi at 65 mph going down the highway on wet roads. as long as all 4 are moving at the same speed it wont hurt anything. now for 4-low, you have to stop, go to neutral, hold the brake and switch to 4-low. same way to take it out.

The manual in my Explorer said 55mph and under you can shift on the fly, don't know what the manual in my 09 F150 says but I am sure it has to be the same. Just make sure your driving on wet roads, not dry pavement. To shift into 4wheel low you need to be stopped completely.
