Give it the Boot (Ball Joint Boot Replacement)

Your vehicle may be wearing boots right now and you might not even know it.  They're called ball joint boots.  They're actually protective, flexible things that protect parts of your suspension (called ball joints) from all the hazards the road can fling at them.  If one of those ball joint boots fails and you don't get it replaced, the ball joints themselves could wind up failing, a repair that can be even more expensive. 

Ball joint boots not only keep things like rocks, salt, water and dirt out of your ball joints, they also help the ball joints keep their lubrication inside and working properly.  To do that, the boots have to be made of a flexible material, sometimes rubber, sometimes a synthetic.  They do take a beating, exposed to temperature extremes and debris, and eventually they can tear or crack just because of their age.  Unless someone is keeping an eye on your ball joint boots, you may never know there's a problem.  That's why when you regularly take your vehicle in to a repair facility for other things like oil changes and routine maintenance, a technician will inspect the ball joint boots to make sure they're still in top shape.

If they're not, your service advisor will let you know. Take care of that soon and you may avoid having to replace the ball joints themselves or other suspension parts which may be much more expensive.  Often it's best to replace boots on both sides of the vehicle since they frequently wear at about the same rate. 

If you want to make a fashion statement, some ball joint boots come in various colors other than run-of-the-mill black.  And some aftermarket boots are made of a more durable material than the original equipment that came on your vehicle.  Some drivers get a real "kick" out of flashy ball joint boots!

The Matt Davis Auto Basic Guide To Synthetic Oil

Synthetic motor oil has been around for a long time, and more and more new vehicles are leaving factories with synthetic in their engines. But a lot of drivers don't really know much about it.

Let's start with conventional oil – the kind folks are used to. Conventional oil is made up of naturally occurring hydrocarbon chains, which means its molecules are long and have various lengths. Like a pile of pencils, some of them new and some of them used.

Synthetic oil is man-made. Its molecules are more uniform and regular in shape – more similar to marbles than pencils. Some synthetic oil starts with a petroleum base that's modified and others are entirely synthesized from other materials.

Synthetic motor oil works better in both hot and cold temperatures. It's more chemically stable so it doesn't readily evaporate or break down in the high heat produced inside your vehicle engine. This means it resists turning to sludge, which is a real engine killer.

Remember that marbles and pencils thing we were talking about? Well, that makes synthetic oil slipperier than conventional oil which means less friction in your engine. Your vehicle engine runs cooler, wears less and lasts longer. You also get a boost in power and maybe even an improvement in fuel economy.

Synthetic oil also lasts longer so you change it less often – which is great for the environment. With longer oil change intervals, you need an oil filter specifically built for the longer service life of synthetic oil. Talk with your friendly and knowledgeable Matt Davis Auto service adviser about synthetic oil and synthetic blends – they might be just what you need to improve engine performance and extend the life of your vehicle.

Things Aren't Always What They Seem

If you drive, you know at some point, something's going to go wrong with your vehicle.  And sometimes, it's pretty easy to figure out what's wrong, like a flat tire.  But sometimes your vehicle's symptoms can be really puzzling.

One driver in NC was heading to work on a hot July day and noticed when he pressed the accelerator, sometimes it wouldn't do anything. He also noticed his cruise control wouldn't work and his traction control light was constantly on, very unusual.

He was trying to figure it out, but none of it made any sense.  His cruise control had always worked perfectly, his traction light never had gone on before and there was never any issue pressing on the accelerator.

It was time to take his car in for a professional diagnosis, and boy, was he surprised that it was a freak accident he'd had the previous WINTER that was the root of his problems.  You see, in January, his car had slipped on ice when he was in reverse and had gently tapped a tree.  That caused a tiny crack in his rear stoplight. 

That crack had gone unnoticed until that July day.  Turns out a summer rain allowed water to seep into the taillight casing, so this time when he drove to work, there was enough moisture inside it to cause his stop light to stick on.

When the stop light is on, the car's computer is programmed to act as if the driver is pressing the brakes. It also disables the cruise, accelerator and cruise control when the brakes are on, producing all of the symptoms.  Replacing the stop lamp switch fixed everything.

So, while some things that go wrong with your vehicle are pretty obvious, many seemingly defy all logic. That's when a trained technician can scope things out, replace the right part and get you going again.
