Let me start by saying that your wheel bearings keep the wheels on your vehicle. Did that get your attention? In this article we’ll discuss more about wheel bearings and how you can keep them doing their very important job.

Wheel bearings are pretty simple parts. They’re made of high quality steel and are engineered to last 100,000 miles or more if properly cared for. The bearings do two very important jobs: First they allow the wheel to freely rotate with as little friction as possible. Second, they support the weight of the vehicle. For example, if your car weighs 3,600 pounds, each wheel has to support approximately 900 pounds. That’s a lot of heavy lifting over many, many thousands of miles.

Even though wheel bearings are relatively simple, they need to be in near perfect condition to do their job. The bearings are packed with heavy grease to lubricate and protect them. A seal keeps the grease in and water and dirt out. It’s when the seal starts to leak that problems begin. The grease can become contaminated; causing the wheel bearings to overheat and ultimately fail.

The first sign that your wheel bearings are in trouble is an unusual noise coming from a wheel. It could be a chirping, growling, rumbling or a cyclic sound. The noise could get louder or even disappear at certain speeds. Your technician can inspect for bearing wear by lifting the vehicle and checking for play in the wheel.

Now some wheel bearing assemblies are factory sealed. That means that they cannot be serviced – they can only be replaced. Those that aren’t sealed can be serviced on schedule. The bearings are removed, cleaned and inspected. If the bearings are still good, they’re re-installed – if not, they’re replaced. They are then packed in grease and a new seal is installed.

If your vehicle has a factory sealed wheel bearing assembly, the entire assembly needs to be replaced when trouble arises. Unfortunately, the parts are pretty pricy – but they usually last about 150,000 miles as long as the seals hold up.

Now, even a good seal cannot keep out water that’s exerting pressure on the seal. So if you’ve driven through hub deep water your bearings should be cleaned and repacked if they’re serviceable. If you have factory sealed bearings, you just need to watch for signs of premature failure.

If your wheel bearings can be serviced, your owner’s manual will recommend an interval, usually around 30,000 miles.

Now, if you have any sort of trailer, don’t forget its wheel bearings. They probably need to be serviced even more frequently. This is especially true for boat trailers that are used to launch the boat by backing it into the water. These should be serviced every year, usually at the end of the season so that the bearings don’t have the opportunity to sit and rust all winter.

So what happens if wheel bearings fail? Well, the wheel can literally fall off the vehicle. I don’t need to tell you how bad that could be. So check with your service adviser and see if your vehicle’s wheel bearings can be serviced and when it’s recommended. Listen for warning signs. If you’ve been fording streams or puddle surfing after rainstorms, be especially vigilant.

About 90% of our driving decisions are based solely on what we see. So having a good pair of windshield wipers is extremely important.

We’ve all experienced the frustration and fear of not being able to see clearly during a storm, or when our windshield is just dirty. In fact, it’s estimated that 46,000,000 motorists are driving with wipers that can’t adequately clear their windshield in a storm.

It seems like your wiper blades are always at their worst when you need them the most. If that sounds like you, you’ve got plenty of company. 78% of drivers only change their wiper blades after the blades function so poorly that they become a safety hazard.

We need to change our thinking. Instead of blades being something to replace when they fail, we need to consider wiper blades as an important safety component. Then we’ll stay ahead of the storm.

You really ought to replace your wiper blades twice a year; in the spring and the fall. If you live in a place that has harsh winters, you may even want to get special winter blades in the fall.

Winter blades are designed to resist freezing. Speaking of winter and freezing conditions, if your car has been sitting for a long time and the windshield becomes frozen, don’t use your wipers to clear off snow and ice. That can just shred your blades and may even damage the wiper motor.

Your wiper blades live outside; freezing cold and blistering sun. Over time, they become hard and brittle, and then tear. They also lose their flexibility and just don’t clear the windshield effectively. Worn wiper blades aren’t just a safety hazard; they can also scratch your windshield. That may require replacing the entire windshield – a big cost for such a little part.

AutoNetTV recommends you replace worn blades right away. Your local service center can provide you with a quality replacement blade. They cost about the same as they would at the store – but installation is included at the service center.

Of course you also need washer fluid to help your blades do their work. Even though your local service center will top off the washer fluid with a full service oil change, it is a good idea to have some extra fluid at home. It’s a good idea to keep a bottle in the car if you’re on a road trip.

Always use windshield washer fluid. Plain water, even that fancy French bottled water, just doesn’t cut it. It can freeze in the fluid reservoir or on the windshield itself, making things worse. Besides, water won’t do as good job of cleaning your windows. So follow these tips to keep your windshield clear and your eye on the road.

Your cooling system is very important.  It circulates coolant through the radiator and your engine to protect your car from overheating. There are five main components to the cooling system: the radiator, the radiator cap, the hoses, the thermostat and the water pump.

The water pump’s like the heart of your cooling system, circulating the fluid throughout.  It’s a small pump that’s driven by the engine: usually by belt, but sometimes by a chain or gear.

The water pump only operates when the engine’s running. Water pump failure is pretty routine.  Some start failing at around 40,000 miles, but most fail by 100,000 miles.  Consult your owners’ manual or service technician to see what’s recommended.

Since a water pump either works or it doesn’t, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fail or they begin to leak.  It’s possible to have a leak from a cracked water pump, but it usually leaks at the gasket where it attaches to the engine.

So how can you tell when the water pump is failing? If you can hear a low-pitched grinding sound coming from the water pump – it’s got a problem.  If you can see coolant in that area, you’ve got a leak.

Some water pumps are driven off the timing belt.  They might be under a plastic cover so you can’t see the water pump.  Look for coolant on the driveway.  If you see some, have your service center check it out.

Most timing belts need to be changed at 60,000 miles – some longer.  It’s a good idea to change your water pump at the same time if it’s one of those that’s driven off the timing belt.  To start with, 90% of the work’s already done with the timing belt change. And, if you don’t, and develop a leak later, you’ll have to change the belt again along with the water pump because the belt will have been contaminated by the leaking coolant.

You can replace your water pump with a brand spankin’ new one or with a rebuilt pump.  Rebuilt will save you some money, but ask your technician what he thinks. Don’t feel too bad if your water pump gives out.  They will all wear out eventually.  Your service technician can get you back on the road and on with your life.
