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 McPherson 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.

Do you have a Clue (Get the Most Out of a Service Visit)

When you head to the doctor, you probably have it in your mind what you're going to say about why you don't feel good.  That way your doctor can use that information to diagnose your problem. You might want to think of that same approach when you take your vehicle in for a repair.

Experts say what will help the service advisor most is for you to bring in some well-organized descriptions about your vehicle's issues.  You might even want to write them down so you don't forget.  Is there an unusual smell?  What does it smell like?  Does the problem happen first thing after starting out? If there's an odd sound you hear, is it dependent on speed?  Does it change when you turn a corner?  

Keep your expectations realistic.  Some conditions may take a long time to diagnose and repair.  If you go thinking you'll be in and out in no time, you might be disappointed when you're told there are other customers ahead of you and you may have to come back tomorrow.  If you can make alternate plans to have someone pick you up and take you back when the vehicle is finished, that way you won't feel like you've wasted your time. 

Most importantly, be available for any communication from the service advisor.  If they have your cell phone and they have a question or need an approval for a repair, the sooner they reach you, the sooner things can move forward. 

The service facility wants your experience with them to be good just as you do.  With a little help from you, they'll get your vehicle back on the road and you'll have a smile on your face.

Timing Belt Service to Save Big Bucks in Du Quoin

Your engine is like a finely choreographed dance. All the parts have to work together. If the timing is off at the ballet, dancers crash into each other and fall down. It the timing is off in your engine, it may not run at all. One of the most intricate dances in your engine has to do with the combustion cycle.

Your vehicle engine has cylinders in which a piston travels up and down. At the top of the cylinders are valves that open to bring in the air and fuel. And there are valves that open to let out the exhaust after the fuel has been burned.

Call McPherson Automotive at (618) 542-9203 for answers about your timing belt, or drop by our Du Quoin, IL, service center on 1 E Park St.

It's critical that the values be timed to open and close at precisely the right time in the combustion cycle, or the engine will run poorly or not at all.

The timing belt is responsible for rotating the shafts that control the valves. It's vital and precision work. Timing belts are made of very tough, flexible material. They can last a long time. But they eventually wear out and can break. The consequences can be disastrous.

In some engines, the valves actually protrude far enough into the cylinders that they could come in contact with the piston. If the timing belt breaks, the pistons will smash into the valves. Valves get bent or broken. If the engine is spinning fast enough, the broken parts will shred the cylinder head as well. Repairing this damage can cost several thousand dollars.

It's a sad day when this happens; especially since it usually can be avoided. Manufacturers have issued recommendations for when you should replace your timing belt. For some engines, it's at 60,000 miles/97,000 km. For others it's at 90,000 miles/145,000 km or more. If you're approaching 60,000 miles/97,000 km or have passed it, make sure you check your owner's manual or with your Du Quoin auto service advisor at McPherson Automotive for when the timing belt should be replaced. Don't let this one slip by.

Now some timing belts are visible and can be inspected. Others are hidden under a protective cover and are hard to get to. Some timing belts also drive the water pump. If you have a leaky water pump, the coolant will contaminate the timing belt and could make it fail sooner. So if you have this kind of engine, get it in to McPherson Automotive for an inspection right away if you have a coolant leak.

Most people in the Du Quoin area with this engine design end up with a new timing belt when they replace the water pump. And when you're having your timing belt replaced on schedule, check with your McPherson Automotive auto service advisor to see if it makes sense to install a new water pump, even if it isn't currently having problems, since most of the labor is already being done any way for the timing belt replacement.

As a heads up; larger engines will often have metal timing chains rather than belts. The chains don't need to be replaced like belts.

We've already told you how very expensive it can be to get your car running again after a timing belt fails. You also need to know that replacing the timing belt is very labor intensive and is one of the most costly maintenance services you will have. So if you will be at the point where your timing belt should be replaced in the next year or so, ask for an estimate from McPherson Automotive in Du Quoin, IL, so you can begin to prepare for the expense.

We at McPherson Automotive, your Du Quoin service center, can be a valuable partner. Please take advantage of our knowledge and experience.

Give Your Engine Clean Fuel with a New Fuel Filter from McPherson Automotive

Your vehicle requires plenty of clean fuel to run. If your fuel contains contaminants, your fuel injectors will eventually become clogged up. When this happens, your vehicle engine may not get the proper amount of fuel at the correct pressure to run at peak performance. This hurts performance as you drive around the Du Quoin area. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.

That's why all vehicles, including vehicles, come equipped with a fuel filter. The job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and keeps them out of the fuel stream. Of course, like all filters, it will eventually get clogged up and need to be replaced at McPherson Automotive in Du Quoin.

If your fuel filter is clogged, the vehicle engine can't get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a bypass valve that will allow unfiltered fuel through when they are clogged. This keeps your vehicle engine running but doesn't protect it from  contaminated fuel.

Du Quoin drivers may find that they need to change their fuel filter at McPherson Automotive more frequently as their vehicle ages. Over the years, additional sediment and rust accumulates in the fuel tank and can be drawn into the fuel system. Your fuel filter stands guard at the gates to your engine to protect parts and to maintain performance.

Differential Service

When you're driving and turn a corner, you probably aren't aware of all that's going on with your wheels.  The outside wheels have a longer distance to travel than the inside wheels, so there are gears that allow the wheels to go at different speeds when you turn. 

That set of gears is called a differential.  In front-wheel drive vehicles, it's by the transmission and called a transaxle.  Rear-wheel drive vehicles have the differential, naturally, on the rear axle. Many all-wheel and four-wheel drives add a center differential since power has to go to the front and rear wheels. (Some newer vehicles power wheels with electric motors, but that's a whole different story.)

Time and distance traveled eventually can take their toll on the differential, and you may notice some noises you hadn't heard when your vehicle was newer.  Sometimes you'll hear a whir that might change in pitch when you turn.  You may hear clicking sounds when you're moving.  Others describe rumbling sounds coming from underneath during a turn. Another symptom of possible differential problems may be vibrations or shakes the faster you go. 

All of these could be signs that you have problems with a differential. One common cause of differential problems is the gears aren't getting enough lubrication.

These can all have serious effects on your driving.  You may find it hard to turn, or your wheels may lock up. That could put you or drivers around you in a dangerous position. 

It's better to take care of differential problems before they get too serious.  Bring in your vehicle so we can have a technician check yours out.  They can see if there are any differential fluid leaks or failing gaskets.  In some cases, we may recommend your differential fluid be replaced.  And if there are any mechanical issues, some components may need to be replaced as well. 

When your differential is maintained, you'll be doing your vehicle a good turn.
