Thom's Four Wheel Drive

Every day you drive, you're sitting behind the dashboard. But how in the world did it get that name? Back in the days of the horse-drawn carriage, horses would kick up dirt and mud on the driver and passengers, "dashing" debris against the carriage. So those who built carriages began installing a board to protect them. So, dash-board. Dashboard. The dashboard is still there, though changed quite a bit from the early days. Now its main purpose is to house the controls and instruments for your vehicle's systems. Of course, you have the speedometer, tachometer and gas gauge. But there are four warning lights you need to pay attention to on your dashboard and instrument panel. Some of these may even be gauges, depending on your model of vehicle. Regardless, paying attention to them is a good idea if you want your vehicle to keep going as long as possible. Oil pressure—The oil pressure light will come on if your engine doesn't have enough pressure in its system. Low oil pressure means ... read more

Every vehicle on Illinois roads has a differential, and it is important to the proper operation of the vehicle.  But most CHICAGO residents don't have a clue what it is.The differential compensates for differing wheel speeds. For example, when you turn, the inside tire on the turn travels a much shorter distance than the outside wheel. So the inside wheel of the vehicle must move at a slower speed than the outside wheel. Without a differential, the wheels would hop and scrape while turning.Have you ever seen the large bulge in the middle of the rear axle of a truck? That's the differential. In a rear-wheel drive vehicle, the differential is located on the back axle. Four-wheel drive vehicles and SUV's have differentials on both the front and the rear axle.You might expect that the differential is located on the front axle of a front-wheel drive vehicle. You'd be right. But the differential is called a transaxle on a front-wheel dri ... read more

When properly aligned, all of your wheels are pointed in the same direction. Your vehicle will track true and handle the way it is designed. CHICAGO drivers often associate our wheels being “knocked” out of alignment with an event like a major crash, hitting a pothole, curb or some other object. While these can certainly take your wheels out of alignment, the bumps and bounces of everyday CHICAGO driving take their toll on wheel alignment as well. Your car can lose alignment over time with just normal driving. When your wheels are out of alignment, the team of automotive professionals at Thom's Four Wheel Drive in CHICAGO can return your wheels to the factory settings. Most owners’ manuals suggest an inspection every year or two.Give us a call.Thom's Four Wheel Drive4118 N PULASKI RDCHICAGO, Illinois 606417735775701http://thomsfourwheeldrive.com

If you've walked through the automotive fluids section of an auto parts store in CHICAGO, you'll know how overwhelming the sheer number of products available can be. How do you know what's right for your vehicle?As you know, these fluids all serve a function in making your car run as you drive around the CHICAGO area. Your vehicle manufacturer has specified a particular type of fluid for every system from the motor, to the cooling system, brake fluid and so on. When you realize that not every variation is applicable to your vehicle, the task becomes more manageable.First let's talk about why there are so many varieties. Starting with motor oil, we see that manufacturers match the properties of a particular weight or type of oil with the design needs of the engine. For example, engines with sophisticated valve trains often require a thinner weight of oil.Some vehicles around CHICAGO come from the factory filled with synthetic oil and the ... read more

A lot of people get custom wheels in CHICAGO. When you do this yourself (over the internet . . .) you could run into trouble if you're not careful.

There are several important factors that go into how often CHICAGO drivers should replace their wiper blades. Of course, the more you use your wipers, the faster the blades will wear out – especially if you use them on an icy windshield. Whether it’s a lot of bugs and road grime from Illinois freeway driving or lots of wet weather – your blades get a work out and start to wear. But your wiper blades break down even when they aren’t used frequently. They are damaged by sunlight and temperature changes as well. The rubber in the blades can dry out and crack and eventually fall apart. Check your wipers: If they’re not doing their important job, have them replaced at Thom's Four Wheel Drive in CHICAGO.

Do I keep my old vehicle or buy a new one? It's a question most CHICAGO drivers ask themselves at some time or another.Generally, what it comes down to is the choice between a car payment and the possibility of repair bills.

Perhaps you've found yourself driving when something all of a sudden splashes on your windshield, obstructing your view. You know that sinking feeling when you try to turn on the windshield washers and no fluid comes out. Now you're blinded even more. What can you do? The best thing is to make sure your windshield washer fluid is always topped off and ready for these situations. You probably figure you'll grab a bottle of that blue stuff you see in the store. But is that really the right choice? One thing you know isn't the right choice is plain water. It can freeze when temperatures drop. Plus, when it's close to the freezing mark outside, spraying water on your windshield can freeze, turning it literally into frosted glass and blinding you suddenly. Water freezing in your vehicle's washer lines can also damage them. There are different types of windshield washer fluid made for different climates. Many have alcohol to prevent them from freezing; their label will usually tell you at wh ... read more

With the weather getting colder, you might be tempted to start your vehicle up, let it idle for 15 or 20 minutes and then get in the nice, cozy cabin.  Some vehicles offer remote starting that let you do that from the comfort of your home or apartment.  But is letting your vehicle idle like that good for it? Manufacturers say it doesn't harm the vehicle.  They say it's because modern vehicles are made differently from those in the past.  Just about all newer vehicles employ fuel injection which uses computers to adjust the amount of gasoline that goes into the cylinders.  The engine gets only the fuel it needs, taking conditions into account. Older vehicles, on the other hand, used to use carburetors.  When you started a cold engine, the carburetor wasn't able to adjust the gasoline amount depending on conditions.  Some of the gasoline would mix with oil and the pistons wouldn't get the same lubrication as they would with undiluted oil. So yes, you ca ... read more
