Thom's Four Wheel Drive

We've all been there.  You park your vehicle on a steeper than usual hill and worry about it rolling down while you're running your errands.  So you decide you'll use the parking brake.  When you get back, you release the parking brake, hit the ignition, put it in gear and—uh, oh—you can feel the parking brake is still on.  It's stuck.  What do you do now? Welcome to the world of infrequently-used parking brakes.  Yes, they do stick for several reasons. It's common for components to corrode and get locked up.  Sometimes if you have applied it extra hard, it can jam.  Could be a rusty cable, could be a spring that doesn't return the brake to its disengaged position.  Some pieces just break when they're stressed for the first time in a while. A caliper or the pivot arm it's on can also stick. There are a few things you can try to unstick it.  Carefully rock your vehicle by putting it first in drive and then reverse.  You ... read more

Have you ever driven a vehicle without power steering? If you have, then you probably appreciate how much easier it is to drive today's modern vehicles. Before power steering, all of the force to turn a vehicle had to come from the driver's arms. That's why old cars had such large steering wheels: they needed plenty of leverage to steer. There were some CHICAGO folks who had difficulty driving because they just weren't strong enough.Power steering is now standard on all vehicles, but there are several ways that power can be delivered. Most vehicles use a hydraulic power steering system system. In this system, a serpentine belt from the engine powers a pump that pressurizes the power steering fluid. The pressure activates hydraulics that provides steering power.Other vehicles use an electric pump to pressurize the power steering fluid rather than the belt-driven pump. Some newer vehicles actually have electric motors that provide steering power and don't use steering fl ... read more

You've likely heard how important oil is to your vehicle's engine. Did you know that there's one part that's responsible for holding that oil so you can use it every day? It's called the oil pan, and it sits at the bottom of the engine. The oil pan is a vital, though simple, part of your engine's lubrication system. Oil circulates through parts of your engine to keep them lubricated. It reduces friction so everything works smoothly. Without oil, friction would quickly destroy your engine. The oil pan keeps that oil contained in the lubrication system, so it's important that the oil doesn't leak out. Since it's a metal part attached to another metal part, there is a gasket between the oil pan and the part of the engine it attaches to. Various things can put stress on the oil pan and gasket, including weather extremes, the speed you're traveling and the condition of the oil. You may drive over a couple of bad roads and kick up debris onto your oil pan. All this wear and tear, heat and ti ... read more

  Today we're talking to CHICAGO drivers about shocks and struts. They're so easy for Illinois folks to forget about because they last so long and wear out so slowly. But your shocks are really responsible for keeping your tires on the road – so they're very important.Without shocks, your wheels would be bouncing over bumps and lifting on corners. The shocks push the tire down to the road to maximize traction. Good shocks equal good ride quality and safe handling for CHICAGO drivers. There's a difference between shocks and springs. Springs support the weight of the vehicle, keeping it suspended up off the axles. The shocks moderate the rebound motion as wheels hit bumps. Now a strut combines a shock and a coil spring in one compact unit. It's best to replace all four shocks at the same time. That way you'll have even, predictable handling at all four corners. Anything less could be dangerous. Visit Thom's Four Wheel Drive to have you ... read more

It's bad enough when you mistakenly leave a window open in your vehicle on a rainy day and you find your carpet soaked.  But what in the world is going on when your windows are closed tight, not leaking and you STILL wind up with wet carpet? The answer could be something you might not even know your vehicle has. And the answer is? Drains. And those drains can get clogged.  Yes, your vehicle has several drains with tubes or hoses attached to them that you really never see.  There are some in and around the hood that channel rainwater down to the ground.  There are some that take condensation from the air conditioner and allow it to flow outside.  And if your vehicle has a retractable sunroof or moon roof, there are small drains at each corner that connect to tubes that go through the vehicle body down to an exit near the ground.  Considering all the leaves, dirt, dust and other debris your vehicle encounters on a daily basis, it's not surprising that these ... read more

You probably have heard that expression, "A stitch in time saves nine." In other words, if you fix an issue at its early stages, it will prevent a much more difficult problem later. That's certainly the case with your vehicle, and here's a true story to demonstrate it. A driver noticed his vehicle was due for an oil change, so he took it in to his service facility early in the morning so he could wait while the work was performed. The technician routinely checks the battery on vehicles just before extreme weather is approaching (cold or hot), so with winter coming up, he hooked up the load tester (it measures voltage while a load is put on the battery). It showed the battery wasn't holding a charge well. The technician checked the manufacturing date on the battery, too (most batteries have a date stamped in code somewhere on them). The date showed it was five years old. While batteries can last more than five years, many technicians say you should expect to get anywhere from three to s ... read more

When we CHICAGO residents get a car repair bill, we really shouldn't be surprised to find “diagnostic fees” as one of the line items. When we get a computer fixed, there is usually a charge for the time it takes to diagnose the problem. When we go to a medical doctor, most of his fee is for his ability to diagnose what's wrong. It's no different with our vehicles.Some diagnoses are fairly simple. Brake repairs at Thom's Four Wheel Drive usually require only a visual inspection, for instance. But other problems are much more difficult to diagnose. An intermittent engine problem, for example, takes time and expertise to pinpoint.Modern vehicles have multiple computers that monitor a variety of sensors throughout the vehicle. When one of those sensors has a reading that is higher or lower than the standard parameters, the computer turns on the Check Engine light. Technicians at a service center such as Thom's Four Wheel Drive in CHICAGO can scan the engine's computer for a tro ... read more

You've just arrived at the store shopping and you're ready to head home.  You put your key in the ignition and… oh, no! The ignition won't turn! What do you do now? Don't panic.  There are some things you can do to get going again.  The first thing to do is see if you have a locking steering wheel, an anti-theft feature that was introduced around 1970.  Sometimes it sticks.  Move the steering wheel side to side while you try to turn the key and you might be able to get it to release.  Another thing to check is to see if your vehicle is in gear.  Most vehicles will only allow you to start the ignition if it's in park or neutral.  If you have an automatic transmission vehicle and it is in park, try jiggling the shift lever and try the key again.  Sometimes the safety mechanism doesn't properly make contact or gets a little sloppy.  If both of these don't work, it could be your vehicle's battery is dead.  Some newer electronic ... read more
