Air Bags for Sale Pro Auto USA prides itself on their knowledge of airbag function and design. Airbags are a crucial occupant protection device which activate automatically in cases of collision or impact. Checking airbag functionality is a very important matter, and we make it easy to find airbags for sale. How Do Airbags Work? They have a central control unit that contains sensors, like accelerometers, impact detectors, gyroscopes, brake pressure indicators and wheel rotation sensors. The sensors are used for specific applications, depending upon the airbag location and function. These parts can be difficult to find. How Do Sensors Work? Upon an impact, a sensor alerts the ACU (airbag control unit) which triggers the release of propellant from inside a gas generator. The gas instantly inflates a thin, fabric bag. When body pressure is exerted against the bag, it releases the expanded gas from small vent holes, gradually deflating. Depending upon the severity of the collision, the control unite can trigger one or several airbags for any number of passengers. Types of Airbags Many are used in vehicles, particularly newer models which protect every type of directional impact and shock pressure a vehicle can experience. The types include front, shaped driver airbags, side door and side torso, side tubular or curtain, knee and rear curtain. Each type is monitored for pressure changes by a sensor, offering complete body protection in most accident scenarios. Common Issues Faulty operation is usually first detected from a dash indicator light, with the key in the Off or On position. Sometimes, a blinking dash light accompanied by a buzzing noise under the ACU means you have a grounded cable under the steering wheel. A bad fuse can keep the […]
Differentials for Sale
Differentials for Sale Pro Auto USA knows the importance of a differential and it’s key component functionality in the automotive vehicle. We also know how much of a pain it can be to find the right one for your car. What is a differential? Commonly called the rear end or pumpkin, it is a large case that contains various gears and is usually located at the rear of the vehicle, unless of course it is a front-wheel drive vehicle. They are housed in a container that is a combination of a transfer box and transmission. The differential gets its input power from a driving source, typically a drive or propeller shaft. It then transfers rotational energy via gears through the axle and onto the drive wheels. This permits the two outbound drive wheels to turn at different speeds when the vehicle makes a left or right turn. The outside wheel, in a turn, rotates faster and travels farther than the inside wheel. The speed of one wheel changes the rotational speed of the other wheel so there remains a synchronized balance or ratio. Limited slip differentials drive both wheels at the same time by using a clutch mechanism, and at the same time, permit the ratio of wheel revolution to change in a turn. Simple differentials use a ring and pinion gear to transfer torque energy to the wheels. When do I need to replace my differential? How do you know if your differential is worn or malfunctioning? A rear end will produce a loud knock or clunk when the transmission is shifted from neutral to drive or neutral to reverse. The clunking noise indicated excess play in the gears, a chipped tooth or a […]
Differentials & Axles for Sale
Differentials & Axles for Sale Pro Auto USA knows that automotive axles are an important part of any vehicle’s drivetrain system. An axle is commonly a shaft or link from the differential (rear end gears) to the drive wheels. Some have joints and some have splines. Axles function independently, slowing or speeding up the drive wheel, depending upon the turning direction of the vehicle. They receive the power or engine torque directly from the rear case differential, or in the case of a front-wheel drive, the CV or constant velocity joint. Axles receive constant stress and shock from sudden acceleration and gear shifting, which makes them vulnerable to bending and breakage. A bent axle can throw the rotational axis of the rim-tire into an out-of-round condition which can cause serious road jarring and vibration. Smooth axle rotation is essential in a well balanced drive-train that must perform perfectly during all manners of engine speed and maneuverability. Pro Auto USA carries a vast inventory of axles for all makes and models of vehicles on the road today, either foreign or domestic. Such makes include Ford, Chevy, VW, Dodge, Hyundai, Nissan, Jeep, Honda and many others. Axles are available for 2-wheel or 4-wheel drive car or trucks, including the different configurations: tandem drive, non-drive axles and single drive types. Our axles include high efficiency gearing, the proper weight and ratio specifications and the correct axle-to-brake design. We carry everything from used to re-manufactured axles for every customer application. You can be assured of the correct fit, design and performance criteria. We sell only the highest quality parts and components, whether they are tested, functioning used axles or brand-name re-manufactured units. Our re-manufactured axles come complete with warranties […]
