I just bought a 2002 Ford Explorer XLT with a 4.0 liter engine. I
would like to know how fast I can drive the truck in the 4 wheel drive
high setting (highway driving)? I have never tried 4 wheel drive low.
I think the truck has a sensor that activates 4 wheel drive when the
tires slip. Any help would be appreciated.

Do not drive in 4WD on dry pavement, you will break something rapidly.

True, not the mention that at speed in 4wd drive if you get into a
skid your kinda screwed because you will not be able to steering out
of it and given that explorers tendancy to roll over at times I would
avoid all high speed 4×4 operation that could put you in a skid.

Care to explain this?
Mike h 2007-08-24 03:42:52
What are all the settings you have on your control for 4wd? A 2002
Explorer should have the Control Trac system. That should give you
4Auto, 4High, and 4Low. In 4 auto, you can leave that on all the time
and drive anywhere you want. 4High should only be used in slippery
conditions at normal speeds. 4low should only be used in slippery
conditions when you need to pull something heavy, or try to get out of
a stuck situation.
In 4Auto, the system monitors speeds between the front and rear of the
truck and will electronically actuate a clutch pack in the transfer
case to move power to the front wheels if it sees slip occurring
between the front and rear. So most of the time the system is in 2wd
mode, but will switch to 4wd as necessary to keep the wheel speeds
the other 4wd modes lock in the transfer case effectively using
gearing to force the front and rear wheels to spin at the same rate.
If you drive in 4HI on dry ground, at best you’ll experience very odd
steering behaviors, at worst you’ll blow up the transfer case.

Thanks Mike H,
You gave me the answer I was looking for. I just
experimented with the 4 wheel drive. It does have 3 buttons, 4 wheel
auto, high, and then low. I keep it in 4 wheel drive auto. I have been
looking for more information than the ford manual gives. I think it
would be a good idea for the ford manual to explain this a little

Most of the ‘owners manuals’ these days are just boilerplate cut-and-
paste from the legal deparment. if you are lucky you get about three
pages at the end to show part numbers for light bulbs and fluid type
and capacity. I looked up Snow Plowing in the Bronco manual, went to
the page indicated in the index and found this:
*Do not plow with this vehicle*
Yeah, sure. Tell that to all the Broncos you see with plows on the
front. Usenet and web forums will always be here for you, though.

Yeah, and just about every ford truck owners manual ever made says this
truck not equipped for a slide in camper.
