When Metal Meets Metal (Wheel Bearings)

What part of your vehicle has little metal balls inside that are lubricated and allow you to cruise on down the road?  They are wheel bearings, and automotive designers might argue they are human beings' second greatest invention of all time (the first is, of course, the wheel!).

You have a wheel bearing at each wheel.  They allow your wheels to turn freely, minimizing friction that would ordinarily slow you down when metal meets metal.  When one of your wheel bearings starts to go bad, it lets you know. A wheel bearing does its work quietly when it's in good health but starts getting noisy when it isn't.  People describe the noise differently.  Sometimes it sounds like road noise, a pulsating, rhythmic, sound.  That pulse speeds up when your vehicle speeds up. 

Here's what's happening when you hear that sound.  As mentioned, the bearing has these little metal balls inside a ring.  They have a lubricant inside to reduce friction between the balls; modern wheel bearings are sealed and they're intended to do their job without any maintenance. 

Wheel bearings take a beating; you hit some rough potholes or go over some uneven railroad tracks. Sometimes water can get into a bearing and reduce the ability of the lubricant to do its job.  Time starts to take its toll, too. When the lubricant isn't reducing friction like it should, the bearing can heat up. One of those little balls can start shedding pieces of metal and soon those shards start grinding up the other balls.  Friction takes over and soon your wheel isn't turning smoothly. That's what's causing the sound.  If a wheel bearing is not fixed, it could eventually seize up completely, and you can be stranded.

It's a lot easier if you heed the early warning signals, that pulsating noise.  Now, sometimes a similar noise can be caused by a bad tire, but in either case, it's important to have it checked out. Our Westside Automotive technicians will be able to tell you fairly quickly what the problem is and offer a solution.

Wheel bearings generally don't fail often and usually last from 85,000-100,000 miles/140,000km to 160,000km. But consider them a long-term maintenance item that, once fixed, will keep you heading smoothly to the next destination.

Slipping into Fall (Driving with ABS Brakes)

As the weather changes over from hot to colder, drivers will have to deal with more slippery streets.  And it's important to know how to drive with the brakes you have on your vehicle. 

In the 1970s, anti-lock braking systems (ABS) started to be installed on vehicles and they've been a game changer for drivers.  Most modern vehicles have ABS and it's important to know how to drive with them.

In older vehicles without ABS, the driver applies the brakes by pushing down the pedal.  That, in turn, sends braking pressure to all four wheels at once.  But all four tires don't have the same traction because the road surface they're each on isn't exactly the same.

ABS allows sensors to determine when particular wheels are slowing down more quickly.  The ABS then reduces braking pressure to the wheels that are about to lock up.  That way the wheel turns and the tires keep some grip. (You have to have grip to stop.) It's kind of what drivers try to achieve when they pump the older-style brakes without ABS.

Another engineered feature of ABS is that it makes sure your front wheels will continue to rotate and maintain some traction.  That's important because the front wheels are used to steer, and being able to steer gives a driver more control in a quickly-changing situation.  So ABS is all about stopping as fast as the road surface will allow but at the same time enabling the driver to maintain control. 

ABS is designed for the driver to put steady pressure on the brake pedal and let the vehicle’s computerized system handle the braking.  Pumping the pedal in a vehicle with ABS can defeat what the system is trying to do to help you maintain control.

Because stopping techniques in a vehicle with ABS are different than those without, it’s important to know which brakes you have so you can operate them accordingly. 

If you have any doubt, consult your service advisor.  ABS involves sophisticated technology and must be maintained in order for it to work properly.  Your service advisor can recommend a maintenance schedule for you to follow so your ABS is always on the ready to help you stop when you need to.

The Best Book that's Not a Best-Seller

Sometimes the movie is better than the book, sometimes it's the other way around.  But when it comes to your vehicle, the best book of all is the owner's manual. The plot is simple: Owner wants long life and dependable performance from the vehicle, manual has the way to achieve that long life and dependable performance.

And yet, it's amazing that some people will own a vehicle for years and never even crack this book.  They'll only read it when they absolutely have to, for things like finding out how to change the clock. 

Ok, so you're probably not going to rush right over to your glove box and start reading the owner's manual cover to cover.  We know that.  But just think of what you can get out of it.

Consider this.  Those who wrote or helped write this book include the engineers who designed it and the people who tested and refined it.  They know more about your vehicle than anyone, period.  They know how long a part is likely to last and what you need to do to take care of it. They know how far a distance or how long a time you can drive before you have to change certain fluids in it.  They know what temperature it can reach before things will start to break.

And they've put your vehicle model through torture, testing it in the absolute worst conditions to see how to make it stand up to more abuse than it will ever receive.  They've then torn it down, examined it and, in many cases, redesigned the parts to make them even better. 

And they've put down—in fairly minute detail—this blueprint that, if you and our experts at Westside Automotive follow their suggestions, will make it very likely that your vehicle will serve you well for a long time.  If you don't follow those suggestions, all bets are off.

We didn't even mention that the owner's manual tells you how to operate everything in your car.  How to adjust the heat and air conditioning, how to pair your smartphone with the audio system, how to program your key fob so it won't sound the horn when you lock your vehicle.

Have you lost your manual or did you buy a vehicle that didn't come with one?  Many are available either online or in paper form. If you don't know where to begin with such a long book, try a couple of pages a week, just three minutes.  You’ll discover your vehicle does things you never even knew it could do.  And the movie will never be as good.

I NEED All Wheel Drive (Pros and Cons of AWD)

So winter has arrived and you don't feel confident in how your 2-wheel drive vehicle does in the snow and ice.  You envy all those people with all-wheel-drive (AWD) and 4-wheel-drive (4WD) cars, trucks and SUVs.  You start thinking, "I need one of those.  I'll be able to go anywhere without any worries."  The truth is there might be another option for you that you might not have thought of. 

Sure, you've seen the ads that tout the advantages of AWD and 4WD, and some of the videos make it look like they can handle everything Mother Nature can throw their way.  The truth, though, is that vehicles with drive wheels at all four corners can't stop any more quickly than those with 2-wheel-drive.  Yes, AWD and 4WD vehicle have advantages when it comes to acceleration, but when it comes to stopping and handling, they generally don't. 

If you buy a new AWD or 4WD vehicle, you are going to spend thousands of dollars.  Maintenance and upkeep costs are higher due to the vehicle's increased complexity and weight, and you're likely to take a hit in fuel economy.  So, what's the option we mentioned above?  It's simple.  Winter tires. 

If you have a front-wheel-drive (FWD) vehicle with winter tires, you'll notice a tremendous difference in your winter traction and stopping than the all-season tires that are on most vehicles.  One tire company, Michelin, wanted to find out which was better in the snow: an AWD car with all-season tires or a FWD car with winter tires.  And they found while the AWD car could get going a little more easily, in most of the other comparisons, the FWD car with winter tires handled equally or better and stopped in a shorter distance.  The optimal combination would be, of course, AWD or 4WD with winter tires.  But one major consumer testing magazine found that only about 12 percent of their subscribers who drove AWD or 4WD vehicle in the snow for more than 6 days in the previous winter even used winter tires!

So a set of winter tires may give you the handling and stopping you're looking for and for a lot less cash than a new AWD vehicle.  Consult your service advisor for some recommendations.  You may be pleasantly surprised at how you can handle winter roads without having to handle a new, big, fat monthly payment for a new vehicle.

All Lined Up (Alignment Inspection)

When you head down a straight road, does your vehicle pull to one side?  Do you feel vibration in any of the wheels? If you've noticed any of these things, it's probably time for you to get your wheel alignment checked.

When your vehicle left the factory, its wheels were parallel to each other and perpendicular to the ground.  That maximizes traction for good steering and braking. Every time you take your vehicle on the road, normal wear and tear will affect your alignment. Hit a bump, a pothole or a curb and all those little knocks will add up

Bad alignment not only can cause your steering wheel to pull unevenly, it can also wear your tires out a lot faster than they should. In fact, if you look at your tires and see one side of the tread is a lot smoother than the other, it could be another sign of bad alignment.

Since different problems can cause similar symptoms, the first thing our trained technician will do is test drive your vehicle. Then, they'll check the front end and steering linkage as well as look for tire wear.  Then, the technician will put your vehicle on a lift and use computerized diagnostic equipment to measure alignment angles so they can precisely align your vehicle's components.

There are different kinds of alignments.  One is a front-end alignment that aligns components of the vehicle's front axle.  Another is a thrust alignment that makes sure the front wheels are lined up with the direction the rear wheels are pointed.  A third type is four-wheel alignment which is usually used on all-wheel drive and  4-wheel drive vehicles.  It's also recommended for front-wheel drive vehicles that have independent rear suspensions.  It makes sure the angles of all the wheels are where they should be relative to each other and also the vehicle's body or frame.

Your steering wheel should be perfectly centered if you are heading straight down the road, so the technician will adjust it so it is. Finally, they'll take your vehicle back on the road for a final test drive to make sure it's performing the way engineers intended.

Your service adviser can recommend how often you should have your alignment inspection, since it depends on the type of vehicle you drive (SUV, sporty car, etc.) and your driving environment.  Properly aligned wheels can help your vehicle perform better and save you from expensive repairs down the road.
