Round and Round (Wheel Balancing)

In a perfect world, all wheels and tires would be perfectly round and weigh exactly the same at every point of the wheel.  Unfortunately, they're not, and if they're out of balance, they can reduce the lifespan of your tires, make your vehicle shake like a carnival ride, and maybe even damage a few suspension parts along the way.  You don't want that!

Wheel balancing, sometimes known as tire balancing, is a process by which a technician makes sure your tire/wheel assembly has evenly distributed weight.  If it isn't, it can give your ride bad vibrations.  If you feel your vehicle's steering wheel shaking, it can mean unbalanced wheels in the front. If you can feel a vibration in your seats, it could be unbalanced rear wheels.

In addition to your vehicle vibrating at higher speeds, there are other signs that your wheels are out of balance. You may see uneven tread wear, or you may notice you aren't getting the kind of fuel economy you used to. 

When you experience these problems, bring your vehicle in, and we can put your wheels on a machine designed to detect any imbalance.  The technician will start your wheels spinning, and a computer will determine how much weight is needed where.  Then, the technician can add small weights on the inside or outside of your wheel rim to precisely balance out the uneven weight.  When the wheel is balanced correctly, it will spin evenly and smoothly.

Sometimes your vehicle will hit a pothole or object in the road that dislodges one of those weights, which can throw that wheel out of balance again.  If so, you'll have to bring it in to have that corrected

Some drivers confuse wheel balancing with wheel alignment. Alignment is making sure the wheels are perpendicular to the road and parallel with each other.  Sometimes your vehicle will need both balancing and alignment done at the same time.

No vibrations are good vibrations when it comes to your wheels.  Bring your vehicle to us, and we'll perform a balancing act to keep your vehicle riding smoothly down the road.

Bad Vibes

Your vehicle has a way of letting you know when something's wrong. Consider a vibrating steering wheel. It certainly didn't do that when it was new, so that shake is trying to tell you something.

There are a few things that can cause your steering wheel to vibrate as you drive down the road.  One of the most common is out-of-balance tires.  You may not only feel that wobble in your steering wheel, you might also feel it in the tires.  Sometimes it's not there when you're driving at lower speeds through residential areas, and sometimes it starts when you hit highway speeds. 

So what is tire balance anyway?  Well, you have a rubber tire that fits around a metal wheel.  It should have the same weight all the way around.  If it doesn't, it will start getting the shakes.  Ever load your washing machine so that all the clothes are at one side of that drum that spins?  When it hits the spin cycle, it can throw that washer against the wall. 

That's the same thing that's happening with an out-of-balance tire/wheel combination.  A technician has special equipment to figure out where to put small weights on the wheel to get things back in balance again.  But it could be that you hit a pothole some time ago and bent the rim.  Or your tire isn't as round and even as it once was.  That could be due to age, damage or wear and tear. The technician will know and offer you options.

Another possibility for that vibrating wheel is a faulty brake, such as warped rotors or a sticky caliper.  All of these issues can be evaluated as part of regular, routine maintenance with us.  There are many things that cause vibrations in your wheels.  But you don't want any bad vibes when it comes to your vehicle. 

Don't Stack the Mat

In the sloppy cold weather months, you might be tempted to pick up an all-weather mat and throw it on top of the mats you already have in your vehicle. After all, double protection is better, right? In this case, wrong. Here's why.

It's important to keep the accelerator and brake pedals clear so they can function the way they are supposed to. Stacking mats in the driver's side footwell can make them sit up too high on the floor. That can, in turn, jam your accelerator pedal forward, causing your vehicle to unintentionally speed up; it may get stuck in that position. Same thing applies to the brake pedal. The mats can get caught underneath it and prevent you from stopping.

Here are some other good practices when it comes to mats. It's best to get those designed for your vehicle. They are shaped to fit your specific car, truck, van or SUV. Ill-fitting mats can have the same untended consequences as stacked mats.

Good mats will have either a Velcro-type fastener on the back of them or a hook that fits into a hole in the mat. That way, the mat stays affixed to the floor so it doesn't slip and cause problems.

One more thing to keep in mind. If you have objects rolling around your vehicle, let's say under the driver's seat, just think about what happens when you jam on the brake. That object is thrown forward and can get caught in a pedal. You might find the accelerator stuck or the brake pedal inoperative.

Your service advisor at Matt Davis Auto can recommend the right mat for your vehicle. The right mat may save your carpeting, the wrong one may cost you an accident.

Cool Running (Water Pump)

Your vehicle is like you in a way.  When it gets hot, it needs to be cooled down.  And one of the key parts to keeping it cool is the water pump.

Now, that's a bit of a misnomer.  It IS a pump, but it's pumping coolant, not pure water.  Cooling off your engine is vital since it builds up heat when it creates power by burning fuel.  Your water pump acts as a way to recirculate that coolant.  It goes through a series of tubes and hoses through the engine where it picks up heat, then is sent off to the radiator to get rid of that heat.  Cooled off, the coolant is recycled through the water pump to start the journey again.

The water pump works by taking mechanical power from the engine, usually from a belt.  Obviously, that belt has to be in good condition and adjusted properly or else the water pump won't be able to do its job.

Here are some things to look for that will signal problems with your water pump.  If your heat gauge is erratic or showing a much higher than normal temperature, that could be a sign of trouble.  Another is if you hear a whine under the hood.  And if that gets louder when you go faster, get it checked right away.  You may see steam coming out from under the hood or coolant may be leaking. 

These signs signal that it's time for you to have a technician check to see where the problem is. Some water pumps are powered by a timing belt.  If your vehicle has that design and your timing belt is due for replacement, sometimes it's a good idea to replace the water pump too, even if it's working properly.  That's because the labor to replace the timing belt can be expensive and it may be wise to proactively take care of the water pump while it's disassembled.

Your service advisor will explain the options available and offer the best path to keeping your water pump doing its job.  Your engine's life depends on it.
