Many CHICAGO drivers probably don't think of their shock absorbers as an important safety system; but that's just what shocks and struts are. They're all about ride control – keeping your vehicle tires in contact with the road and managing body motion.Every time you hit a bump or pothole on a CHICAGO road, your tire wants to bounce up. The bigger the bump, the higher the bounce. Your shocks or struts push down on the tire to maintain the traction you need to start, stop and turn.If you've ever ridden in a vehicle with bad shocks, you know how it wallows on corners. The front end dives when you hit the brakes and the rear end squats when you accelerate. It's not only uncomfortable, it is difficult to handle.You may have heard vehicles described as having “flat cornering." That means that when you take a corner, the body doesn't roll very much. When shocks start to get worn, your vehicle will roll more on corners. The weight of your vehicle's bo ... read more

When they hear the word suspension, many drivers in CHICAGO may think back to those energetic days of grade school. Well, your vehicle's suspension is actually a good thing because it keeps your vehicle up off the road and helps provide a comfy ride around CHICAGO. Its job is to keep your wheels firmly planted over bumps and through curves. Your suspension system has many parts. If you look under your vehicle, it's basically everything that connects your wheels to the vehicle's frame. These are heavy duty parts that do a lot of work. They need to be inspected for damage and excessive wear at least once a year. A good time for this is when you get your annual alignment service at Thom's Four Wheel Drive. Here are some warning signs of suspension problems: the car pulls to one side it wanders the steering is erratic you see uneven tire wear you experience a poor ride or handling you see oil leaking from shocks Basically, you just don't feel in control when you're ... read more

A good suspension system gives a vehicle a smooth, even ride while providing CHICAGO drivers with good handling and control. But like any system on your vehicle, parts of the suspension system can wear out, leading to a lower ride quality and safety concerns. So it's a good idea for drivers in CHICAGO to remember their suspension system in their schedule of preventive maintenance. Springs do most of the work of the suspension system. The most common types of springs are coil and leaf, but air springs and torsion bars are becoming more common. The body of the vehicle is “suspended” by the springs.If springs were the only working component in your suspension system, however, you'd spend your travel time bouncing up and down like a bobblehead. That's where your shocks come in. They keep the rebound, or bounciness, of the springs under control. Shocks also keep your tires on the road, which keeps the driver in control of the vehicle. Some vehicles have struts in their suspensi ... 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

If you've ever ridden down a rough road on your bicycle, you know how hard a ride it can be.  Yet drive down the same road in your car, truck or SUV and it miraculously will smooth out the ride.  That's because it is equipped with shock absorbers.  They are built to dampen impacts from road irregularities.  But after taking hundreds of hits from potholes, railroad tracks and curbs, your shock absorbers can wear out.  Besides the rough ride that can cause, there are other ways your vehicle's performance can be affected. When it comes to braking for example, you may take a longer distance to stop.  That's because shocks help keep your tires in contact with the surface of the road.  If the shocks aren't working properly, the tires won't make contact like they should.  So when you slam on the brakes, your vehicle will take longer to stop. Consider what worn out shocks are doing to your tires.  Since the bumps aren't being dampened as much, your ... read more

You may have noticed your vehicle going through lean times.  By that, we mean it's literally leaning to one side.  When you notice that, you should get it checked out at your service facility soon because you could have a serious problem. Many things can cause a vehicle to lean.  You may have problems with your struts, shocks or springs.  They all work in tandem to make your ride more comfortable.  The struts bear the weight of the vehicle's body, the shock absorbers employ a piston that keeps your tires in contact with the road and controls movement of the vehicle's body.  Springs also absorb impacts from uneven road surfaces. If these components get stuck, either too high or too low, they cause your vehicle to lean.  That's because that side of the vehicle isn't at the height it is designed to be.  A technician will determine where the problem is.  Outside elements such as moisture plus hard knocks to these components can weaken them, even ... read more
