FORD 2013 Explorer v.2 - Manual (Page 359)

Power is supplied to all four wheels through a transfer case or power
transfer unit. Four-wheel drive vehicles allow you to select different drive
modes as necessary. Information on transfer case operation and shifting
procedures can be found in the Transmission chapter. Information on
transfer case maintenance can be found in the Maintenance chapter.
You should become thoroughly familiar with this information before you
operate your vehicle.
On some four-wheel drive models, the initial shift from two-wheel drive
to four-wheel drive while the vehicle is moving can cause a momentary
clunk and ratcheting sound. These sounds are normal as the front
drivetrain comes up to speed and is not cause for concern.
How Your Vehicle Differs from Other Vehicles
SUVs and trucks can differ from
some other vehicles in a few
noticeable ways. Your vehicle may
be:
• Higher – to allow higher load
carrying capacity and to allow it
to travel over rough terrain
without getting hung up or
damaging underbody
components.
• Shorter – to give it the capability
to approach inclines and drive
over the crest of a hill without
getting hung up or damaging
underbody components. All other
things held equal, a shorter
wheelbase may make your vehicle quicker to respond to steering
inputs than a vehicle with a longer wheelbase.
