Beware of Potholes! (Avoiding Pothole Damage)

You may live in a region where roads become pockmarked with craters known better as potholes.  They're caused by moisture seeping through a compromised road surface that can freeze, expand and literally punch holes in the road.  And when your vehicle hits one of those holes that's big enough, the impact can flatten a tire, bend a wheel or tear apart a suspension component. 

To minimize pothole damage, leave enough room between you and the vehicle in front of you so you can see the road surface and any upcoming potholes.  That way you'll have time to slow down and steer around them.  Also, if you see what looks like a puddle of water, it may be hiding a pothole underneath, so treat it as if was a pothole.

If you keep your tires inflated to the manufacturer's specifications, they're more likely to withstand hard impacts.  And the slower you're going when you hit a pothole, the less likely you are to break something.   But if you do find you've hit a pothole pretty hard, here are some signs to watch out that could signal damage.

• Your vehicle pulls to one side
• The steering wheel shakes
• You hear noises or clunks coming from your suspension
• Your steering wheel is not centered when you are going straight

These are all symptoms you should have checked at your vehicle repair facility as soon as you can. The longer you wait, the more damage you may be doing.

You also may find after hitting a pothole hard that the tire on that wheel is flat. Try not to drive any more on that tire since you could do a lot more damage to the tire and/or wheel. A call to roadside assistance may save you money in the long run by limiting the damage to what's already done.

The Flat Fix that Fits (Tire Repairs)

Can you think of anyone who likes getting a flat tire?  Of course not.  But when one of your tires winds up with a flat or leak, whether it be from things like hitting a curb, running over a nail or picking up a sharp stone, it's time to have someone who knows what they're doing take care of it.

If you're thinking you'd like to avoid having to buy a new tire, you wonder if a patch or plug will suffice.  It depends where the puncture is and how big the hole is.  Most tire experts will say if the hole in the tire is less than ¼ of an inch or 6 mm, a patch can work.  But a patch likely won't work if the compromised part of the tire is on its shoulder or sidewall.

Here's why.  The shoulder of a tire is the part between the sidewall and tread and it's usually rounded.  It's under a lot of pressure, more than even the sidewalls. And because of that curved shape, it's hard to get a patch or plug to hold.

The sidewall is the side of the tire.  Sidewalls flex a lot when you drive, and the strain can cause a patch or plug to loosen up.  A weak spot in a sidewall is much more likely to fail and cause a blowout.  So if you have damage in the sidewall or shoulder, that tire is a good candidate for replacement, not repair.

If you have a cut or gash in your tire, it's possible the cords that strengthen your tire have also been cut.  That weak spot can spell trouble, and this type of damage usually means you should get a new one.

Your service advisor can tell you what the appropriate action is to take when you have tire damage.  You may be able to get good results with a patch, or you may have to replace one or more tires.  Your safety is riding on them.

Have a Ball! Know your Ball Joints (Ball Joints)

We all have joints in our own skeletal system, but did you know your vehicle has some joints of its own? One of the most important is called a ball joint.

One of the interesting things is that it's somewhat similar to the ball and socket joints we have in our hips and shoulders.  A ball joint allows two parts it joins together to move in more than one direction at the same time.

Think about your wheels.  They have to move up and down when there are bumps in the road but in sideways directions when you are making a turn. As you can see, the ball joints are important for your steering and handling to work correctly.

Since ball joints do so much, they can wear out and become loose.  When the ball wears down or the socket gets worn, there can be too much play in them.  It can get so bad that the ball can come out of the socket and your wheel can fall off, a dangerous situation.  Ball joints can also seize up.  Some of them are sealed and never require maintenance; others require periodic lubrication.

Here are some signs that your ball joints are going bad:

• Your vehicle pulls to one side
• You can hear a clunking noise coming from a wheel area
• Your tires are wearing unevenly, especially on the inside

The earlier a failing ball joint is discovered, the better. The best way is to have regular inspections by a technician.  Your service facility will periodically check ball joints at intervals recommended by the manufacturer. The cost to replace them can vary widely depending on whether you have a vehicle with a 2-ball or 4-ball configuration.  Also, sometimes just the joints can be replaced, but other times they are part of a larger control arm assembly that has to have all the parts replaced at the same time. 

Your vehicle's proper steering, handling and tire wear all contribute to a better, safer driving experience.  Make sure your ball joints are up to the job.

Emergency! (Vehicle Emergency items)

"I never expected it could happen to me." Countless drivers have said that after they've had an emergency turn their lives upside down. So before that happens to you, let's thinking about planning ahead for an emergency with a few things you should keep in your vehicle.

• Road flares. If you've ever driven by a disabled vehicle sitting at the side of the highway at night, you know how terribly hard it is to see, especially in bad weather like rain.  If you are the one in that broken down vehicle, you run the risk of being hit by a vehicle whose driver literally may not be able to see you.  The best emergency signal includes one or more road flares.  There's a reason police officers and firefighters carry them in their vehicles.  When you see a series of burning red flares at the side of the road, you know something serious is going on.  These are far more visible at a much longer distance than nearly any other portable signal device.

• Fire extinguisher.  Thousands of vehicles catch fire every year.   Most fires start small but can get out of control. It's vital to have a fire extinguisher in your vehicle, and there are several small ones designed especially for the job.  Since many different types of vehicle fires can start, make sure the extinguisher you choose will handle every fire from gasoline to electrical. Some have handy mounting brackets. And keep it up to date!

• Flashlight.  Sure, your cell phone likely has a light in it.  But you will need that phone for communication if there's an emergency. Plus, the light’s just not that bright.  So carry an LED flashlight designed for automotive use.  LEDs produce a lot of light with little power; plus, many of those designed for vehicles include a lantern which will light up a wider area. It’s vital if you have to read your vehicle's jack instructions or tend to an injured person.

• Drinking water and snacks.  If your vehicle breaks down during bad weather and you may be forced to stay with it for a long time, you'll need food and water to survive until help can arrive.  These are simply the necessities of life, so have a small supply on hand, just in case.

Other things like basic tools, a first aid kit, a space blanket and jumper cables are also good ideas.  Many service repair facilities offer these items for sale, and you can ask your service advisor for suggestions.  While it's fresh in your mind, plan a shopping trip and put together your own emergency kit now.  Sure, you can put it off, but you may find yourself stuck in a difficult situation, saying to yourself, "Only if…"

Passing the Test (How to Prevent Emissions Test Failure)

Vehicle emission testing has become ubiquitous in North America and for a good reason.  Clean air quality is important for the environment and all of us.  Since vehicle emissions are among the main causes of air pollution, emission testing can alert you to problems in your vehicle than can be fixed so it won't needlessly pollute.

Emissions tests are looking for certain toxic gases internal combustion engines produce, such as nitrogen oxide, particulate matter, non-methane organic gases and formaldehyde.  Emissions control systems reduce these gases if they are working properly. 

The best way to minimize pollution is to keep those vehicle systems working properly, and periodic inspection and maintenance is the key.  So if you want to make sure your vehicle will pass an emissions test, it helps to know what might go wrong.

Let's start on the easy one.  Your gas cap could be loose, allowing vapors to escape into the atmosphere.  The most common solution is to replace it.  Or your air filter may be dirty.  A dirty air filter may push your hydrocarbons pass the acceptable level.

Now to the more complicated things.  The mixture of fuel and air in your engine may be tilted toward the "too much fuel" side.  That could cause problems for your vehicle's catalytic converter, a device that converts toxic gases from your exhaust into less toxic pollutants.

Your vehicle has a closed system that prevents fuel tank vapors from escaping into the air; it's called the EVAP system.  A technician can track down problems.

Vehicle engineers have gone to great lengths to minimize the amount of pollution your vehicle produces.  Your vehicle's manufacturer recommends how frequently those systems need servicing.  Keep those systems in good shape and you're likely to pass emissions tests with flying colors.  Neglect them and you might find your vehicle failing an emissions test.  When that happens, you'll have to get the problems repaired before you can get back on the road.
