When Your Tires are Tired (Tire Replacement)

Tires are so reliable these days that few drivers pay much attention to them.  But tires wear out.  They have a tough job since they are the only point of contact between your vehicle and the road.  They have to get your vehicle going from a stop, keep it going, make sure it is headed in the direction you want it to go, and –importantly – slow and stop it.  

The only time many drivers think about their tires is when there's a problem, such as a flat.  Or, they may lose control when they find their vehicle isn't stopping or steering like it used to.  One major safety organization estimates that 1 out of every 11 crashes is related to a tire issue.  

Many of those problems are caused by tire tread wearing out.  The rubber is worn off by friction after hours and hours on roads.  The sidewalls can also be damaged by your tires hitting curbs, potholes, or other debris. Plus, rubber ages as time passes.  We recommend you let us inspect your tires periodically so we can spot potential problems before it's too late.  

When it's time for you to replace your tires, it's important to know which type is right for your driving habits and what environments your tires usually encounter.  The most common tires are called all-season. As the name says, they are pretty good in every season and their tread lasts a long time.  In other words, they're good all-purpose, all-around tires.

Another option is a performance all-season tire, which has a little more grip but won't last as long. Then there are ultra-high-performance tires (UHP) which have wonderful grip and handling but an even shorter lifespan. They also aren't the greatest in slippery conditions.

For those who live in more extreme climates, especially where there is a lot of snow, winter tires are definitely worth considering because their performance in cold, snowy conditions can make a huge difference in traction, improving steering, and stopping.  Some places require winter tires during certain periods of winter.

Don't underestimate how much of a difference tires can make on your vehicle.  Sure, you probably don't pay much attention to them, but they are one of the most important investments you can make, and they can pay valuable dividends when you need them to come through for you.

Smooth Operator (Shocks and Struts)

Few of us ever drive somewhere without encountering some pretty rough roads, and it's amazing how well our vehicles are able to smooth out the ride. Thank your shocks and struts.

The two parts are similar.  Some cars have shocks in the rear, and struts in the front.  Others have struts all around.  A shock absorber uses a cylinder filled with gas or liquid that's connected to your vehicle's frame and axle.  When your vehicle encounters an imperfection in the road, the shock dampens the motion. 

A strut is essentially a shock absorber mounted inside a spring and can support more weight than a shock by itself.

Shocks and struts take a lot of punishment and wear out.  When they do, your tires are not contacting the road as much as they should, and that can result in a bumpy, unstable ride. Worn-out shocks and struts also transfer the impacts of road imperfections directly to your vehicle's body which can cause further damage to other parts.

You can tell when your shocks and struts are wearing out when your vehicle's ride is bouncy, you feel the bumps and body motion a lot more than you used to, or you may see fluid leaking from the areas near the wheels.

How often your shocks and struts need replacing depends on what surfaces you drive on, how far they've traveled, and how long they've been on the vehicle.  Our technicians can check the condition of your shocks and struts and advise you when they need to be changed.  Shocks and struts should always be changed in pairs.  

Because shocks and struts wear out gradually over a long time and distance, experts recommend you have them checked at least once a year.  Plus, if you know you've recently hit something especially hard in the road, you should have your suspension checked just to make sure it's ok.

Avoiding Exhaustion (EGR Valve Replacement)

No, ERG isn’t the sound a pirate makes.  It’s a part in your vehicle that recirculates exhaust gas to reduce certain gases and pollutants in the atmosphere.  In fact, ERG stands for “Exhaust Gas Recirculation.”

One gas our vehicles may make when they burn fuel is nitric oxide, which can play a big role in creating smog and acid rain.  It’s better for our planet if our vehicles aren’t spewing that into the air.  

One inventive way of reducing it is by taking the exhaust and channeling it back to the vehicle’s air intake system. When it travels through the engine again, its composition is changed, and it comes out cleaner.  It also helps the engine be more efficient.

The EGR valve can fail after a while, and some signs you may notice are the engine is miss firing, it may suddenly lose power or your Check Engine light may come on.  You may also see your fuel economy decrease or hear your engine knock. A bad EGR valve can also make your vehicle fail an emissions test.

There are several different types, including newer ones that are electronically controlled rather than working on vacuum pressure.  They are found in newer gasoline and diesel vehicles. If you notice any of the symptoms of a failing EGR valve, bring your vehicle in so a technician can check to see if your EGR is still up to its “exhausting” job.

Why did my vehicle fail its emissions test?

We all want to breathe clean air and keep our planet green.  One of the ways to do that is by requiring all vehicles with internal combustion engines to pass an emissions test.  That’s because these vehicles can be big polluters.  

Everyone wants their car to pass the test so they can continue their day-to-day driving routine.  But then comes that one day when they tell you your vehicle has failed.  Why does that happen?

One of the most common reasons is that your gas cap is leaking or loose (or maybe you don’t even have one on your vehicle!).  The gas cap is supposed to seal in vapors, but sometimes its seals or gaskets dry out or crack. Replace it, and you’re good to go.

Another common reason your vehicle failed the test is that your catalytic converter isn’t doing its job. It is supposed to convert toxic gases from your engine into ones that don’t pollute the air.  There are many reasons the catalytic converter may not be working.  It may be physically damaged, or the steady flow of exhaust gases has fouled the converter. 

You may have a bad oxygen sensor. It’s supposed to measure how much oxygen is in your exhaust.  This can cause the air-fuel mixture to be too rich, resulting in too many hydrocarbons in the exhaust. Your ignition system may also have problems, such as worn-out spark plugs.  Dirty fuel injectors can contribute to excess emissions.

Believe it or not, a dirty engine air filter may be the culprit. If it hasn’t been replaced for a while, your vehicle may be emitting too many hydrocarbons -  something that will cause your vehicle to fail the emissions test.

You can usually avoid a failed emissions test by maintaining your vehicle regularly.  The best way to do that is by bringing it to our trained technicians, so your vehicle gets the service it needs, scheduled and non-scheduled.  Plus, you’ll be doing your part to keep our air clean.

Differential Essential (Differential Fluid Exchange)

What's the dif? To an automotive technician, it's the differential, a part of your vehicle that helps direct power from the engine to the wheels.  The differential is a gearbox that enables the drive wheels to turn at different speeds (they do that when you turn).  

Inside the differential is a fluid that makes sure those gears and other parts are lubricated since there are a lot of metal moving parts in there.  (Your vehicle may have more than one differential in it depending on the drivetrain.) 

As you can imagine, it's important that the lubricant in those differentials do its job.  Otherwise, the gears may be damaged by heat and friction. The more you drive your vehicle, the more likely it is for that lubricating fluid to break down.

So, it's important to have the differential fluid exchanged every so often.  Your vehicle's manufacturer recommends how often your model should have that done, but a common interval is every 30,000-60,000 miles/50,000 km-100,000km.  Regular exchange of differential fluid can reduce premature wear of the gears inside.

Scheduled maintenance goes a long way to preventing differential problems, but sometimes when they begin to fail, you may hear the vehicle sounding a little louder than usual where the differentials are located.  

When it comes to changing the differential fluid, some have a drain plug in them. Others require the entire cover to be removed to drain the fluid.  There are often gaskets that must be changed at the same time to make sure there are no leaks.
Now when someone asks you, "What's the dif?" You’ll know how essential the differential is and how to keep it running in top shape.
