Thanks to an automotive technology called shocks, we enjoy a more comfortable and controlled ride. It wasn’t always like that, because back when cars were still relatively new machines the ride was bouncy and rough.
Automobile Shocks: How They Work
The common misconception is that car shock absorbers actually support the vehicle’s weight, but that’s far from the truth. What they really do is control any movement in the suspension and springs. To get a little scientific, shocks do this by taking 
the movement or kinetic energy and converting it into heat. That energy is stored inside the shocks’ hydraulic fluid, before escaping into the surrounding air.
If you were to cut a car shock in half lengthwise, you’d see a cross section of how it works. There’s a long piston rod with a piston on one end, which sits flush with the walls of the shock cylinder or pressure tube. Hydraulic fluid sits inside as well.
When the car drivers over a pothole or bump, the piston is forced up and down in the pressure tube. Small holes in the piston, called orifices, allow the hydraulic fluid to pass through. Because the flow is only slight, thanks to the size of the orifices, the shocks are able to absorb the energy transferred from the suspension and vehicle springs.
All shocks provide greater resistance the faster the suspension bounces. This allows for adjustments based on different surfaces, making for a more comfortable ride quality on rough pavement Of course, not all shock absorbers are made equal. Some provide more resistance than others, thanks to factors like the size and number of piston orifices.
Automobile Shocks: Recognizing Trouble
Now that you have a basic understanding of what shocks are and how they work, you’re ready to learn the different warning signs that they need to be replaced. Failure to replace worn shock absorbers not only means you’ll be enduring a rougher ride; it can also lead to damage as the undercarriage comes into contact with the road. That’s why you should always be watching for these warning signs, the taking action as soon as they crop up.
You should know that shocks don’t just suddenly wear out. It happens gradually over time, so you might not realize what’s going on until they’re pretty far gone. That’s why when you’re in doubt, have a trained auto tech take a look to see if the shocks are bad enough to justify swapping them out, preventing serious damage.
Also, know that you can’t just replace your shocks after a set number of miles. How quickly they wear depends on how you drive your car, what the roads are like where you live, etc.
One of the telltale signs of worn shock absorbers is a bouncier ride. If you notice that when you go over bumps in the road, your car dives up and down wildly, that means you need to have the shocks inspected. The problem could also manifest when you drive over a series of small bumps or ripples in a road, with the traction control system light flickering on in the instrument cluster as one or more wheels literally bounces up and down while struggling to attain enough grip.
Most people realize that bottoming-out is a bad thing, so that’s perhaps the most obvious sign of worn shocks. The problem usually first manifests when you go over railroad tracks or have trouble with steep driveway skirts.
If you hear a strange sound whenever the car goes over a bump, that also can signal trouble. As the shocks age and reach the end of their life, they can begin creaking, popping or making other noises that let you know it’s time to have them replaced.
When you hit the brakes hard, like during a panic stop, your car might lean forward slightly before coming to a complete stop. If the front end dives down hard, that can be a sign of worn shocks. The same is true with what’s called acceleration squat. If when you accelerate hard, the back end of the vehicle sinks down, that’s not a good sign.
Too much body lean is another indication something’s wrong. When they’re in good condition, a vehicle’s shocks regulate at least some of the body lean, which boosts handling ability and comfort when navigating through turns.
Perform This Simple Test
You can perform a simple test at home to tell if the shocks on your vehicle are worn enough that they need to be replaced. Push down as hard as you can at each corner of the car, then let go abruptly. If after you release the vehicle it keeps bouncing, you likely need new shocks.

The only way to tell for sure if a vehicle’s shock need to be replaced is to have a highly skilled technician look at them. At T3 Atlanta we have all of the necessary equipment and training to take great care of your car.
Connected to the gear reduction is a linkage, which is what actually moves the wipers back and forth across the windshield. A short cam is the piece that’s attached to the motor’s output shaft. As it spins while the motor runs, a long rod attached to the other end of the cam shifts back and forth. Attached to the other end of the long rod is a short rod, which is what turns the wiper blade on one side of the car (usually the driver’s side). Another long rod connects to the other wiper.
Basically, they’re made of rubber, with metal strips that help them maintain a constant shape. This is so the thin rubber edge that sits against the windshield swipes off water evenly. As the rubber ages, it starts to chip and crack, causing the wipers to leave streaks. Sometimes this streaking is caused by dirt buildup on the wipers, which is why it’s a good idea to clean them when washing your car. 
too technical, there are several gears fixed on two shafts. As the car is shifted into different gears by the driver or a computer, the gears from one shaft engage with the ones on the other. 
causes. Low fluid or the wrong type can cause some bumping sounds. If the transmission is particularly noisy, it could be from serious mechanical damage, such as worn bearings or gears. If the problem includes grinding or shaking, that can be from a worn clutch, maladjustments or other worn components. 
Of course, the brake system is actually set up to multiply the force you apply with your foot. After all, it would be pretty difficult to use sheer physical strength to stop the progression of a 4,000-plus pound vehicle traveling 65 mph. The actual pedal is designed as a lever, which multiplies the force you exert. The hydraulic force also multiplies your effort, routing through the brake lines and a master cylinder before winding its way to the wheels. 
One possible reason for low brake fluid is a leak. It could be present anywhere in the system, which runs throughout the undercarriage. Tracking down a leak can be tricky for someone who doesn’t have the right equipment, experience or training, which is where our techs come in. Ignoring the problem can make it worse, putting you and anyone riding in the car at risk.
Your car’s battery is located under the hood of the car. It contains sulfuric acid and water. There are two metal terminals on top of the battery. One is for the positive terminal and the other is for the negative terminal. The positive terminal can be identified by a “+” sign or the word “positive”. 
Most car batteries can be recycled. If your battery cannot be recycled, you need to dispose of it correctly since it contains hazardous materials. There are ways to make a few bucks off of recycling your old battery.
