Thom's Four Wheel Drive

These days many people in the CHICAGO area are really committed to making their cars last a long time. First thing: you've got to start with what you've got. It'd be ideal if people started with a brand new car, never missed a scheduled service item, paid attention to the severe service maintenance schedule and had regular inspections. But if you've had the vehicle for a while or bought it used, its maintenance history is what it is; and that's where you start.Go through the maintenance schedule for your vehicle and see what's been done and when. Have your CHICAGO service advisor at Thom's Four Wheel Drive do an inspection and come up with a list of stuff that needs to be done. Review the list and prioritize the work, talk about budget and make a plan to get caught up.Making a plan is so important. Suppose you go in for an oil change and learn you need your cooling system serviced, a transmission service and are coming up on a timing belt replacement in the next ... read more

The drive train in your vehicle includes all the components that transfer power from the transmission to the wheels. Those components differ depending on what type of vehicle you drive, namely, front-wheel drive, rear-wheel drive, all-wheel drive or four-wheel drive. The preventive maintenance your driveshaft needs will also differ by what type of vehicle you drive.Let's start with front-wheel drive. In this vehicle, the transmission and the differential are combined in one component, known as the transaxle. The transaxle is connected to two half-shafts (axles), which are then connected to the wheels with a constant velocity (or CV) joint, which is protected by an airtight rubber boot.Thom's Four Wheel Drive service for this type of driveline includes servicing the transaxle and inspecting the CV boot. If the boot is damaged, the CV joint will need to be inspected, and the boot will need to be replaced. If you hear a clicking ... read more

Hey CHICAGO - this is something really amazing: Your vehicle uses 12,000 times as much air as fuel when you drive it. All of that air has to be filtered to keep your engine clean.That's like 100 gallons (380 liters) of air every block! The engine air filter is just another example of a very important but inexpensive part that has to do a tremendous amount of work. And when it works, everything goes well. But, when it doesn't, well, it can lead to problems. Of course, your vehicle manufacturer recommends how often to change your air filter. But like most service intervals, where and how you drive your vehicle in Illinois affects when your filter needs to be changed.Dusty conditions around CHICAGO or polluted city driving means you'll need to change your filter more often. Our trained professionals at Thom's Four Wheel Drive can check your filter for you. In fact, it's often a routine part of an oil change.When you think about it, a clogged air ... read more

One thing all CHICAGO drivers can do to extend the life of their battery is to keep it clean. A greasy, dirty battery holds in damaging heat. Same goes for removing corrosion from the terminals. Thom's Four Wheel Drive can help maintain your battery.Allowing your battery to be deeply depleted – like from using your headlights when the engine is off – is very harmful to your battery. Most automotive batteries can only take that about 10 times before they are ruined.Also, making sure you have a full charge every month or so extends battery life. Either an extended drive at freeway speeds around the CHICAGO are or using a battery charger will preserve your battery’s ability to hold a full charge.Give us a call.Thom's Four Wheel Drive4118 N PULASKI RDCHICAGO, Illinois 606417735775701http://thomsfourwheeldrive.com

With the recent focus in the CHICAGO area on improving fuel economy, we've been told how important it is to maintain our tire pressure.CHICAGO drivers know that tires wear out, but we want to make them last as long as possible because they're not cheap to replace. In addition to saving gas, properly inflated tires last longer. Underinflated tires will wear out more quickly.Some people in CHICAGO wonder if they should add a few extra pounds of pressure when they fill up their tires. Bad idea. In fact, there are very good reasons not to overinflate your tires. For one, the middle of the tread will wear unevenly because the full tread is not contacting the road properly. That also adversely affects your handling. Stop by Thom's Four Wheel Drive to see about tire maintenance for your vehicle.

We live in a disposable society. Everything from elaborate packaging to our clothing. Even cell phones are disposable. When replacement is cheaper than repair, the term "built to last" goes by the wayside. An exception is our vehicles. They're still a very big investment and CHICAGO drivers want to make them last as long as possible.  We also want to make keeping them running as cheap as possible. When talking vehicles, it's all about preventive maintenance. There is an old saying that says, "A stitch in time saves nine," and that is really true when it comes to taking care of your vehicle. A great example is coolant service in CHICAGO.Your coolant not only protects your engine from overheating and freezing, it must also protect cooling system components from corrosion. Over time, coolant becomes corrosive and actually starts to damage your radiator and other parts. That's why you need to have your cooling system serviced on a regular schedule.The same is true for your power ... read more

There are a lot of drivers in CHICAGO who are due for a differential service, but had never heard of a differential before.With front-wheel drive being so common in Illinois these days, the differential is just taken care of during a transmission service, so most CHICAGO folks don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of your mind. It's not uncommon for people in CHICAGO to not know they have a differential, let alone know that it needs service.To better understand what a differential does, think about a track at any Illinois high school. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the longer length of the outside lanes. Staggering the starting lines means that each ru ... read more

Synthetic motor oil has been around for a long time, and more and more new vehicles are leaving factories with synthetic in their engines. But a lot of drivers don't really know much about it.Let's start with conventional oil – the kind folks are used to. Conventional oil is made up of naturally occurring hydrocarbon chains, which means its molecules are long and have various lengths. Like a pile of pencils, some of them new and some of them used.Synthetic oil is man-made. Its molecules are more uniform and regular in shape – more similar to marbles than pencils. Some synthetic oil starts with a petroleum base that's modified and others are entirely synthesized from other materials.Synthetic motor oil works better in both hot and cold temperatures. It's more chemically stable so it doesn't readily evaporate or break down in the high heat produced inside your vehicle engine. This means it resists turning to sludge, which is a real engine killer.Remember that marbles and ... read more

Think of how much abuse your brakes take. Day in and day out, they stop your vehicle when it's going fast and when it's going slow. Maybe your vehicle has been vibrating when you brake, or maybe it seems like your stopping distance is a little bit longer than it used to be. Then it's time to get your brakes checked out. After all, you have to be able to stop if you want to be safe. Nearly all newer vehicles have disc brakes on the front, and many have that type of brake on all four wheels. That makes it likely you'll be getting disc brakes fixed at some time in your vehicle's lifetime. Knowing how disc brakes work is as easy as riding a bicycle. If your bike had hand brakes, you'll probably remember a mechanism that squeezed a couple of pads on each side of your bicycle wheel when you applied the brakes. Disc brakes are similar; but instead of the bike wheel, there's a metal disc instead. If that disc is warped or has irregularities in it, it's going to vibrate. It used to be that roto ... read more

If you've ever been driving around CHICAGO and had a headlamp go out, you've probably just wanted to replace the bad bulb. If your car uses halogen headlamps, they dim over time. So if you just put in one, they won't have the same brightness, which can be distracting and will affect your field of vision.To have your headlights inspected, visit us at Thom's Four Wheel Drive. We're at 4118 N PULASKI RD in CHICAGO, Illinois 60641. Or give us a call at 7735775701.Experts at Thom's Four Wheel Drive recommend replacing your halogen headlamps every year. It's easy to remember if you do it when Daylight Saving Time changes in the fall. That way you'll have bright headlamps for those long Illinois winter nights.There are other types of headlamps in addition to halogen. There are the old standard bulbs that have been around for decades. These are OK, but you can usually upgrade to halogen. They cost a little more but you can't believe the difference. If you do a ... read more
