Wheel bearings are essential to the proper functioning and performance of your car.They are the part which has to support all the weight of the vehicle and distribute it properly among all four wheels. By providing a smooth, even surface on which the wheels can turn, they also play a major part in giving drivers, passengers and cargo a smooth ride.
As well as supporting the weight of vehicle and occupants, wheel bearings also have to absorb the heat and friction which are generated during typical driving conditions.
Most wheel bearings consist of a set of steel ball bearings, which move around inside a metal frame called a race. This is a bit like a railway track in that it consists of two parallel rings, which should ideally be perfectly circular. The outer rims should be able to hold the bearings tightly, yet still allow the inner bearings to move around freely within this frame.

Disc brake service has become routine for most ­import repair shops. Many shops in the rust-belt service disc brake calipers by simply replacing them with loaded caliper assemblies, but in drier climates, calipers can last for many years and may ­require only routine inspection during a disc brake pad replacement. In order to appreciate some of the fine points of disc brake repair, it’s important to review the basic elements of caliper service.

A bad car thermostat can be difficult on your wallet because it can ruin the car’s engine if you’re not careful. This is a critical component that, when faulty, must be repaired immediately. Read on to know more about the symptoms or warning signs of a bad car thermostat.

The transmission valve body is made up of three major components:

• The upper valve body.
• The lower valve body.
• The manual valve body.

The transmission’s valves manage fluid direction and pressure. They accomplish this through hydraulic circuits that connect to the main transmission housing. The valves receive oil from the governor, which varies fluid pressure in accordance with vehicle speed.

The mass air flow sensor is an important component which the engine control unit depends on. When the flow of air enters the fuel injection system of the engine, the mass air flow sensor will analyze how much air is flowing in there. It will then relay this information back to the engine control unit. From there, the engine control unit will be able to control how much fuel gets injected into the engine. As you may know, there needs to be just the right amount of air and fuel mixed together in the internal combustion chamber of an engine. Therefore, if the mass airflow sensor goes bad then it will ultimately jeopardize the performance of the engine.

​A camshaft sensor is an integral part of the modern automobile. It is one of the devices that helps the engine run smoothly. The camshaft sensor is located under the hood, beside the engine, however, it isn’t always easy to find it. This is because the exact position of the camshaft sensor depends on the car brand. That said, whichever the car, you’ll find the camshaft sensor in either one of three locations: beside the engine block, behind the cylinder head, or in the car’s lifter valley.

A properly working torque converter is something your car’s transmission needs to function. If there is a problem causing it to malfunction then there are some symptoms that your car will exhibit. Here, you will get a brief idea of what a torque converter is and some of the most common ways to tell if yours is going bad. Keep in mind that other problems with your vehicle might show these same signs, so it’s best to check for more than one of these symptoms to confirm that the cause lies with your torque converter.

Modern automobile engineering has made the crankshaft position sensor an important part of the car’s engine. This small device is instrumental in monitoring the engine’s multiple components via the car’s computerized engine management system. The sensor tracks the speed of crankshaft rotation, monitors the engine valves in relation to the pistons, and observes overall engine function.
The crankshaft position sensor is usually placed on the crankshaft near the main pulley. It passes on information, and as with any other component of the engine, when things begin going south, it needs immediate attention. Ignoring the symptoms of a bad crankshaft position sensor will result in rapid wear and tear of the various parts of the engine and will quickly lead to engine wear-out. Fortunately, warning signs of a bad crankshaft position sensor are easy for the driver to detect. Read through the following points and keep an eye out for any one of these warning signs.
