A long time ago, before the advent of the internet, remember how you looked up for information in the fat yellow books- the yellow pages? And then the internet arrived and just one click of the button made it possible for you to find the information that you were looking for. It enabled you to find information about anything and everything- right from the best restaurant to eat in, to the best accessories for your car or best automotive car repair shop in your area, and everything in between.

It told you everything you needed to know (and more) about basic car maintenance and auto repair; wheels, tires motor oil, suspension, brakes ,gearboxes, transmissions, steering, engines, exhaust systems, motors, petrol, gasoline and general car maintenance and tune up. You learnt how the car works and you learnt about the speed of the engine.

Often times, when your car does not give you the mileage that it used to, you think of trading it in and buying a different one-preferably a hybrid. You believe that you are buying something that is more fuel efficient. But a word of caution here! Find out first how much you would get by selling your existing car and also how much you will pay for the new one. Remember your new car will pay for itself only after 5 years so unless you plan on keeping it for 5 years, maybe it isn't worth the trade in.

In case you decide that it isn't worth getting a new car, then it might be worth trying to get better mileage out of your existing car. This is where we come in. We at mufflerman. com provide tips and tricks that help you get better performance out of your car.

There are many automotive stores that offer parts like brakes, mufflers and exhaust systems, transmissions body parts, tires and automobile electrification windshields, and oil changes. They also offer bodywork for the car. Many body shops now offer paint-less dent repair, done by pushing the dents out from inside.

Cars work on the principle of a differential which allows the wheels to rotate at different speeds. Thus in a moving vehicle, the outside wheel traveling around the outside of the turning curve moves farther and faster than the others. The engine is connected to the shaft which rotates at angular velocity. If the engine runs at a constant speed, the rotational speed of each wheel varies but the sum of the speeds of the two wheels cannot change. If one wheel increases speed, the other decreases to maintain the balance.

Another application worth talking about is the differentials in epicyclical gearing. Different differentials make up the gearbox. One shaft is connected to through the clutch to the engine and another to the driving wheels and the third shaft can be braked so its angular velocity is zero. When the brake is applied, the gear ratio between the engine and the wheel is determined. Shifting gears involves releasing the braked shaft of one differential and braking the appropriate shaft on another. Epicyclical gearing is used in automatic cars, and is also used in some hybrid and electric vehicles.

In order to take a look at the engine, the transmission and the air conditioning, you need to crank open the hood which is then supported by a strut mechanism. Most cars open the hood by releasing a cable below the rim of the hood. Identify the right strut that your car needs. A faulty strut prevents you from keeping the hood open. Over time, the worn out strut does not provide the support that the hood needs. While replacing struts remember that they are replaced in pairs. When the bonnet is no longer able to support itself, is the time that you need to replace the struts.

The strut is usually attached to the bonnet and then connected to the engine bay with a clip and pin which allows for its functioning. In order to take it off, you need to first remove the pin. Work your way back to the bonnet and loosen the connection which may be fastened with a bolt or a nut. After you identify the mechanism keeping it in place, use the appropriate tools to effectively remove it without causing more damage.

Fasten the rod to the bonnet securely and then fasten apparatus to the pin and the clip where it connected to the chassis.

Gently release the support and check if the change has been successful.
