Since you already know how to drive a car, you probably feel
your not going to need this information? If that is the
case you are totally and completely, wrong and or misinformed?
We
will discuss: Test-driving several different types
of vehicles in this segment. First lets take the most prominent
vehicle on the road today: Front wheel drive models. These
are the most plentiful and in the highest demand. Front wheel
drive vehicles operate exactly in a manner as described in
the term “ Front wheel drive” The power source
that propels the vehicle down the road, does so in the front
section of the vehicle, rather then the older 50’s –80’s
models that were “ Rear Wheel drive” models.
Your everyday basic front wheel drive vehicles are Toyota’s,
Honda’s, all Japanese models except trucks and SUV’s.
Domestic models such as Ford’s, Chevrolet’s and
Chryslers are the same except for a few select models. The
European imports fall into the same categories exactly the
same as the Japanese and domestic models.
Make note: We are interested in Noises of any kind: Knocks,
clicks, clunks, bonks grinding and scraping? Jerks, skips,
lagging and skipping in response to operations
Lets start with our Front wheel model: Remember to buckle
up!
We should decide on several operations to test our front
wheel model. First lets just pull out and use the turn signals.
Notice the blinking indicator on the dash? If it is rapidly
blinking this means a bulb or turn signal lamp is out. While
you accelerate and go with the normal flow of traffic. Do
this at normal driving speeds. As you make right and left
hand turns: Listen for sounds, such as clicking, clunks,
popping and grinding sounds. Clicking sounds might be the
front axles or CV joints. CV joint replacement is an expensive
repair and a further indication of other problems that may
be due to lack of regular vehicle service and maintenance?
Popping may mean defective motor or transmission mounts.
Grinding sounds may be again axles and cv joints but usually
brakes or the power steering pump! While you plan the remainder
of your test drive make sure you include: City driving, Freeway
driving. Turning in a complete circle to the left and right.
Parallel parking. If there are hills or local mountains,
make sure you include these as well. The point to all of
this is to replicate All driving conditions without leaving
anything to chance.
Test-drive Foul wheel drive:
For starters make sure you duplicate every driving suggestion.
Most four-wheel drive vehicles today are actually all wheel
drive although named four-wheel drive. All wheel drive means,
all four wheels have traction. Most Trucks and SUV vehicles
are Part-time four-wheel drive. These vehicles have locking
hubs, and a transfer case that needs to be manually engaged
before four-wheel operation can be available. Locking hubs
have a manual function allowing for the four-wheel operation
to be fully engaged. Make sure these adjustable locking hubs
are easy to turn without the need to use a tool or anything
to force them into position. After you have engaged a part-time
four-wheel drive and are ready to continue with your test
drive make sure you test each level or range. These vehicles
have a low and high range. To properly test the four-wheel
operation make sure you do this off the payment. A proper
method for testing would always be off road. Make sure before
you finish your test drive to execute hard left and right
turns. I recommend you bury the steering wheel to a maximum
turning ration to make sure there are no issues with the
front axles. If you feel the vehicle ‘pitching’ meaning
the vehicle is attempting to recover from the turn. The four-wheel
operation is working correctly. Backing up a distance of
twenty to thirty feet should easily complete and clearing
the four-wheel action. After you have placed the vehicle
in reverse and cleared the four wheel operation and gone
back into Two wheel operation you should be able to accelerate
without feeling any of the four wheel action being engaged
or dragging.
4X4: Four Wheel Drive, All Wheel Drive. Part-Time 4X4
These terms are all supposed to represent the same mechanical
condition. However they are different, not only in name
but in the way they operate. When shopping for a four-wheel
drivel
vehicle, make sure you are buying exactly the product you
are seeking. Many passenger vehicles make a claim as being
4X4’s or four-wheel drive. In truth these vehicles
operate with ONE wheel in the front and ONE in the back
doing the work as apposed to all four working to power
the vehicle.
A good example of a true four wheel drive vehicle is a:
Subaru, The entire line of Subaru vehicles are what is
considered
all wheel or true four wheel drive vehicles. Many manufacturers
say their vehicles are four-wheel drive but truly are not.
This is a buyer beware situation. Again the ultimate responsibility
lies with the consumer or buyer. So the ball is in your
court. Make sure you read the vehicle information. Do not
in any
situation rely on what the salesman is telling you. There
is a pretty good chance you have more knowledge about the
vehicle your interested in then your salesman.
Rear
Wheel Drive: Operation and test-driving: Similar
to the front wheel drive vehicles, only you need not be
afraid
of front axles issues. With a rear wheel drive vehicle the
drive train goes from the engine to the transmission. Then
to the ‘U’ joints or Universal joints. These
can be an issue if they cluck or slam into operation. The
universal joints connect the drive shaft directly to the
rear-end or differential. Most people call it the rear end
simply because it is in the rear of the vehicle. There are
not too many vehicles on the road today that are rear-wheel
drive except for, full size and small size trucks. Many SUV’s
and utility Van’s are rear wheel drive as well. As
for passenger vehicles the Chevrolet Corvette and the Ford
Mustang are the most obvious rear wheel drive models. All
of the previous examples and recommendations for test-driving
hold true for these vehicles. Pay close attention to any
noises what ever they may be. Vehicle manufacturers pride
themselves and boast about the quiet operation of their vehicles.
The only vehicles that inherently make noise are of course
diesels. These vehicles have different method of powering
the vehicle but basic operation is exactly the same.
