| 4-wheeling
can be one of the most exhilarating things to do
outdoors. You have your 4x4 machine, whether it be a
truck, SUV or other and you want to put it to the test.
Here are some basics to get you started:
Safety
Remember, you are in a
machine. The human body was built to withstand an impact
equal to that of a person running and smacking into
something. It was not intended to be strapped into a plummeting
machine dropped from 200 feet or the same machine
propelled at 20+ miles per hour into a tree, rock, or
other stationary object. Be aware of your surroundings,
your capabilities, and your vehicles capabilities to
avoid injury or death.
Also, take care of your
vehicle. They are intended to be used for certain
purposes and can withstand only certain abuse.
General 4-wheeling
As a general rule of
thumb use 4-wheel drive only as necessary and the lower
gear as a "get me unstuck" tool. Don't start
out in 4 low and get stuck in it. The low range should
be used only as needed and not as the gears of choice.
Advanced enthusiasts may have rock crawlers, etc. that
are intended to function consistently in the low range
but they also have vehicles with rolebars, winches,
groups of people in their party that can help them out
of a sticky situation, and much experience to know what
to do.
Find areas that are
approved for offroading and have at it. Be thinking
about 2 moves ahead because you will want to be able to
stop in a place where you can turn around or back out if
you are not able to handle the spot.
Drive at a moderate speed
- fast enough to keep your momentum going and slow
enough to "read" the spot you are about to
take on. You will need to judge how to take each slope,
corner, or bump.
Keep in mind the physics
of a run. How is the corner
banked? How many bumps are in a row? What is on the
other side of the hill's crown? How wet is the grass?
Could there be ice there? Is that mud-hole
"eternal"? Will the tires want to slide into
that rut? etc.
Know what your engine,
suspension, and tires can handle. Not all offroad
vehicles are created equal. A Rav4, Tacoma, and Tundra
will all handle differently and be capable of different
outcomes.
If possible, start your
adventures going uphill so that if you get stuck you can
always go back DOWN to the main road instead of getting
stuck in a situation where you have to climb to get
back.
Hill Climbing
Most often you will want
to get a good run at a steeper hill. You will want to be
prepared to downshift. As you make the ascent the engine
will begin to slow in RPMs. Make sure you know what the
crown of the hill looks like. As you get to the top you
will want to know where to go. If you feel the engine
loosing power, which is common if you are in a higher
gear trying to get a run at it, then you will want to
shift down smoothly so you don't loose momentum. If you
are in an automatic you will want to use the manual
options of 1 and 2.
If you get stuck on the
climb because your vehicle can't handle the full hill or
because of a missed shift, hold the brakes and assess
your situation. If you are sure you can get your vehicle
started again, which is a tough challenge if you are in
a manual transmission vehicle, then put it in granny
gear and inch up the remainder of the hill. If you won't
be able to have enough power or the confidence to get
your foot from the brake to the throttle then ease down
the hill backwards to the nearest safe turning point.
Turn around and go back down the rest of the hill. If
there is no turn around point then back down the hill
the whole way. One tip to backing down the hill is to
put the vehicle in reverse and use the engine gears as
brakes along with foot brakes.
There is no greater
feeling than reaching the top of a tough climb.
The Down Hills
The key here is to use
the engine for partial braking. Ease down the hill in
1st or 2nd gear and use the brakes sparingly as needed.
If you are in a truck be sure not to let the bed slide
down faster than the front. Keep it slowly moving.
The Side Hills
This is the most
challenging, awkward, and dangerous situation to be in.
It is best to remain as level as possible from side to
side. If you absolutely must, inch around a tilting
spot. Don't punch it or any bump could send you rolling
down the hill. Be very careful to keep your sides
horizontally level.
Water
It is very exhilarating
to see a mud or water wall smashing down on the
windshield as the wipers slide back and forth fervently.
You hit a puddle or small body of water causing it to
spray into the air and cover the vehicle. You'll want to
keep a couple of things in mind.
Remember, vehicles need
air to breathe. If you flood a vehicle with water you
will not likely get it going again. The engine isn't the
only thing that must remain water free. From the air
filter box under the hood to the exhaust in the back of
the vehicle there is a pathway that allows air to travel
through the whole power generating system.
When you enter water make
sure you judge the spot correctly. Some vehicle designs
can handle water much better than others. Some can
temporarily deal with water up to the top of the hood.
Some sputter and fail if water gets to radiator level.
It is key to get in and out of the water as fast as
possible.
Some vehicle designs
almost serve as boats if the water is deep enough. They
get very poor traction and get stuck easily. Getting
stuck in a body of water is certain doom for a vehicle.
Water can do a lot of damage to an interior or to the
engine if the situation is prolonged.
Make sure you know what
is under the surface as well. Big rocks or wire can make
a mess of the drive train.
Mud or water holes that
aren't too deep are quite OK and can be very fun.
Splashing around is a blast.
Snow
The adrenaline runs high
when the powder is high and you are plowing through it.
The key: Keep the
momentum going. Don't let a drift slow you down.
Chain up if needed. Your
vehicle manufacture will likely have a recommended chain
to use. Make sure they fit your tires and that you don't
use them anywhere without snow, ice, gravel, etc.
Don't get high centered.
If the tires can't touch the ground you obviously can't
get traction and then the hand digging process begins
(unless you have someone who can tow you out).
Snow can be like a
lubricant if you are not careful. Careful not to get on
a hill where you could slide into danger.
Stay in a gear such that
your RPMs are fairly high.
Be aware of the area and
possible pitfalls.
Make sure you are quick
at hand because if you are moving at a fairly quick clip
you will need to judge and deal with situations
quickly.
Make sure you are very
comfortable driving in snow before getting too daring.
It takes practice to stay out of trouble and it only
takes getting stuck once and having to walk for 5 miles
to be reminded.
Keep some type of long
distance open communication with another vehicle so you
can have aid if needed.
Ice
Imagine you are an ice
skater who ways 2000 pounds, skates on all fours, and
you can move your legs as fast as you want. If you
understand the physics of ice very well you will
probably be able to handle the maneuverings of a vehicle
OK. Otherwise you should begin practicing at a slow pace
and practice a ton. Ice is the trickiest of elements for
beginners to deal with.
The key is to keep
control. The best way to remain in control is to keep
the tires moving in the right direction and at the
correct speed without locking them up or spinning
them.
It can be a blast to
plant the front tire, gun the throttle and spin a tight
360. You also need to know how to do something like that
before attempting.
Try finding an open field
in the cold. Often, if a spring runs through the field
it will freeze up in the winter. The water will overflow
the banks and run into the field creating a huge ice
patch. Powdered snow sits on top and provides the
perfect lubricant to an already slick surface. Start out
slow and be careful. As you get better at it you will
find that there are a lot of variables that can create
quite an exciting ride.
Be careful of snow drifts
and always know where the edge of the ice patch is. Be
very very leery of lake tops. We have seen more than one
vehicle lost through the ice.
When encountering an ice
patch other than a large field you will likely not want
to be playing. The best way to keep traction is to never
lock up the brakes. Sometimes, in fact, acceleration can
help you out of a situation. Always keep the tires
rotating and turn slowly to guide the vehicle. If you
spin the tires, lock them up, or turn to sharply all you
do is cause two slick surfaces to slide together. If you
use the rotating tires then you get a fresh set of tread
every square inch that roles over snow and finds the
friction of the ice. Use slow movements to correct and
guide the vehicle.
If you need you may
attempt to throw a good deal of sand on the ice or use
boards to improve the friction before making a run.
Don't use pine bows because they are very slippery as
well.
Mud
Mud can be the most fun
of any of the 4 wheeling elements. Rooster tails, waves
over the hood and roof, spins and slides define a
4x4.
Start in 2-wheel drive
and gun it (obviously in an open area). Gain momentum in
4-wheel and then shift into 2-wheel again and gun it.
What a blast.
The best time to offroad
in mud is after a good healthy rain has sat for about 2
days. That way there is solid ground a couple of inches
below a sloppy surface. You don't get stuck yet you get
all sorts of dirty.
The only warnings here
are to make sure that you are in a safe area. Sliding's
good when you aren't about to barrel down a steep
embankment into the trees. Also, scout out deep mud pits
before entering. We have seen 4 inches of mud within the
cab of a truck because it was stuck for too long.
Also make sure to clean
out the engine compartment shortly after the adventure
just to prolong the life of the engine.
Gravel
Gravel, mud and ice all
have similar physics. You can spin, slide and get plenty
dirty. 2-wheel drive is usually best for gravel but
sometimes a shift from 4 to 2 with some increased
throttle makes for a cool move.
Be prepared for extra
tire wear and rock chips. The wrong moves can wreak
havoc on your vehicle.
Banked
Corners
A 4-wheeler's best friend
can be a well banked corner. A banked corner is one that
causes the car to lean the opposite direction of the
turn. If a driver is making a right hand turn a banked
corner would have a higher left side throughout the
turn.
Banked corners allow a
driver to use centrifugal to his/her advantage. You can
take a banked corner much faster and much more
aggressively than one that is not. They can also help
you gain momentum on a climb if used right.
Be careful not to over
estimate the corner. Don't get too gutsy. They can help
you but they can be deceptive if there are washouts or
large rocks or if the bank isn't as sharp as
needed.
Also make sure you don't
forget which way a banked corner should lean. If you
make a turn with the bank facing the wrong way you will
have an exact disadvantage to that of a correct bank.
Spinning
This section should be
titled "Coming out of a Spin". We all know how
to get into a spin: make the rear end of the vehicle go
faster than the front. We don't all know how to get out
of it. Most of the time this refers to ice or mud or
something similar (i.e. hydroplane).
The key is actually
counter intuitive. Usually you need to turn into the
spin to gain control before redirecting the vehicle.
Turning into a spin means you have to face the steering
wheels the same direction you are spinning. Your wheels
begin to spin instead of sliding allowing the tread to
stick and pull you in the right direction.
Trouble Spots
OK, so you have been
having a blast spinning, and climbing and making a
mess...and now you're stuck.
If you are lucky enough
at the time to have a winch you are more than likely set
but if you have a winch you are likely not reading this.
For those of us who get
stuck and need some ideas you may consider the
following: A hefty tow rope and a buddy truck are the
best aids. Hook up and both slowly ease into the pull to
not yank off a part of the vehicles. Don't attach a tow
rope to the bumper. Make sure it is on the frame if you
can.
If you are high centered
look to raise the ground under the tires. Use wood,
rock, hay bales, etc. You may even carefully jack up the
vehicle to set it higher than the center stick point.
Fill holes where the tires are with rocks like gravel or
smaller rocks. Don't add a boulder to have to climb
over. Make a path way after the hole with the same high
friction material you use to fill the hole so you can
keep up your momentum. In the end you may have to dig
out whatever is holding you up. You have to be very
creative at times.
If you are not high
centered but just stopped up by the some obstacle or
hole keep the tires facing forward if possible and rock
them back and forth to gain traction. Try not to spin.
If you have momentum and start to spin the tires you may
accelerate even more so they spin rapidly as long as you
have momentum.
A more advanced option is
to rock the vehicle. This works best in a manual and you
have to be good. Start in reverse. Spin the tires. As
you rock back down into the hole quickly shift into 1st
and gun it. You will rock up the other side. As you rock
back down shift to reverse and use the momentum going
back to get higher up the hole wall. Do this back and
forth until you get out or until you see you can't make
it out. The toughest parts are getting from gear to gear
without grinding and in time to take advantage of the
directional momentum.
