Posted on October 15,13 by truck2

Why are wheel bearings vital for Ashland car owners? It’s simple: your wheel bearings keep the wheels on your vehicle. In today’s Duffy’s Repair Service post, we’ll discuss more about wheel bearings and how you can make sure they can do their very important job while you drive around Mechanicsville, Virginia.

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 vital 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 pretty simple parts, 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 at Duffy’s Repair Service 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 expensive – 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.

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 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 technician at Duffy’s Repair Service 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.

Buying the Right Tires and Wheels In Ashland Virginia

Posted on March 21,13 by truck2

Everyone in Ashland Virginia eventually replaces their tires, whether it’s because they’re worn out or they’re just looking for something different. There are so many great tire choices in Ashland Virginia, it can be difficult to sort them out. Let’s group the broad spectrum into several categories that will help in the selection process.

One category is often referred to as “summer tires”. Summer tires are designed to be driven on the road when temperatures are generally above 45 degrees. Their tread design is optimized for traction on dry roads in Ashland Virginia and they’re also able to effectively displace water on rainy roads.

Now the rubber compound gets a little hard and stiff as temperatures drop below 45 degrees as it occasionally does here in Ashland Virginia. And the tread which handles dry roads so well, can get packed with snow or mud – which provides very little traction in those conditions.

So if you live where its summer all year round, these tires will work well for you. If you like maximum performance in warm weather, but still live where it gets cold and snowy, you’ll want to change your summer tires for winter tires as the weather starts to change.

Summer tires can be purchased with an emphasis on handling performance, smooth ride or long life. Your Ashland Virginia tire professional at Duffy’s Repair Service can help you find the right tire for the way you drive.

As you can imagine, winter tires are designed to work very well in snow and ice. Their tread is designed with many channels and grooves that throw the snow out of the tread as the wheel turns. This means the tire is always be able to bite into the snow.

The rubber compound used in winter tires is specially formulated to be flexible at temperatures below 45 degrees. This maximizes cold weather traction. When it gets warmer, the softer rubber will wear faster on warm dry pavement than summer tires, so change them out once the weather has turned.

There’s a range of tires within the winter tire category. If you live where there’s a lot of snow and ice, look for the mountain and snowflake icon that signifies a severe snow rating. If you have milder winters and still want a performance component, they make a winter tire for you as well.

For many people, an all-season tire is the answer. You will give up some of the performance at the extreme ends of the summer tire/ winter tire spectrum, but you will find a long wearing tire that gives both good highway performance and winter traction on our Ashland Virginia roads.

Within the all-season category, there are many choices that you tire advisor can help you evaluate.

Outside of these three main categories, some people in Ashland with trucks and SUVs like a tire that is designed for both on-highway and off-highway use. They can handle the rocks and bumps off-road, but still work well on the street. Again, many options depending on the relative emphasis on on-road verses off-road.

You may want new wheels to go with your new tires – well, there are hundreds and hundreds of styles to choose from. That’s a matter of personal taste. If you want to change the size of your wheels and tires, do get some professional help.

The computers on your vehicle are programmed to the size of wheel and tire combination that comes from the factory. Tire size affects various computer controlled functions like anti-lock brakes, traction and stability controls, speedometer and odometer. Of course, you want these systems to work properly. The computers can be re-programmed for different tire sizes.

And if you want to increase the size of your wheels and tires, you’ll want so help to make sure they’ll fit in the wheel wells of your vehicle without rubbing during turns or over bumps.
