Wheels And Tires - Ford F-150 Owner's Manual

A vehicle equipped with four-wheel drive
(when selected) has the ability to use all
four wheels to power itself. This increases
traction which may enable you to safely
drive over terrain and road conditions that
a conventional two-wheel drive vehicle
cannot.
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 are not cause for concern.

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.
Narrower - to provide greater
maneuverability in tight spaces,
particularly in off-road use.
