It’s happened to all of
us. You get in your car, start driving and something is not quite right.
You turn down the radio and your senses go into overdrive. You hear
something, see something or feel something unusual.
What is it?
The article below was

has
been dynamic in the automotive industry for over 40 years. Mr. Ofria is
currently very active as an automotive journalist where he brings his
diverse knowledge of the automotive industry to bear in articles and new
car road test reviews that he writes for The Family Car website.
Does your car do this?
The
steering wheel vibrates at certain speeds, usually between 50 and 70
miles per hour.
This is usually caused by a
front wheel out of balance. If you feel the vibration only in your seat,
it's probably a rear wheel. In either case it pays to have all 4 wheels
balanced at the same time. You will be surprised at the difference it
will make in the way the car will ride.
My
car drifts to the left or to the right when I let go of the steering
wheel on a straight and level road.
First, check the air pressure
in all your tires, then try driving it again. If your car drifts to the
right in the right lane and to the left in the left lane, it is probably
normal. Most roads are banked to allow for water runoff. Make sure both
front tires are the same size, type and brand. If not, take both front
tires and switch them side to side. If the car now drifts in the
opposite direction, you've found your problem. If the problem is still
there, you should have the wheel alignment checked. However, bear in
mind that while some cars have adjustments to correct pulling problems,
most modern front wheel drive cars do not. If that's the case your
mechanic should check for bent or worn front end parts that can cause
this condition and ascertain whether there are any safety concerns.
When
I drive down a straight road, the spokes of my steering wheel are not
centered.
This is also a wheel
alignment problem, but one that is easy to correct by doing a wheel
alignment. However, make sure the mechanic checks for worn or damaged
parts. If the problem appeared suddenly, possibly after you hit a
pot-hole or curb or something like that, then you've most likely have
sustained some damage which should be checked as soon as possible to
avoid serious tire wear.
There
is a humming noise coming from my tires on a smooth road.
If you have a front wheel
drive car and you haven't rotated your tires in a while, check the rear
tires. Run your hand around the edge of the tread, first in one
direction, then the other (Note: be careful not to injure
yourself on debris or exposed steel belts on the tire). You are
looking for a "saw-tooth" wear pattern between the tread blocks. If the
tread is smooth in one direction but jagged in the other direction, you
may have found some of the noise. Try rotating the tires using the car
manufacturers recommended procedure. You want to make sure that the rear
tires are crossed over to the other side of the car and placed on the
front. This wear pattern is common on front wheel drive cars with tires
that are designed with grooves on the edges of the tread. While there is
a potential for noise with this design, it does have advantages in wet
weather and snow.
When
I drive over a speed bump or a dip in the road, my car bounces 2 or more
times before settling down.
This condition is usually
caused by worn or broken shocks or struts. This condition happens
gradually over the life of the shocks and it is hard to notice the
change, but when they are replaced you should notice a big difference in
the ride and stability of your car.
My
directional signals flash on one side but not the other.
This is a designed in feature
of most directional signal systems to let you know that a directional
bulb has burnt out on the side that is not flashing. The best way to
check them is to put on your 4-way flashers which usually use the same
bulbs as the directionals and look for the bulb that is not flashing. If
all the bulbs are flashing, then there is probably a bad bulb socket or
ground causing excessive resistance. Some mechanics will simply replace
the flasher with a "heavy-duty" flasher to correct this problem and get
the directionals flashing again. But all that accomplishes is to disable
the designed-in warning system of the original flasher and mask the
problem of the bad socket or ground.
