A differential is a key component of a vehicle’s drivetrain. The differential is the unit that allows to maintain traction under a variety of different conditions. By utilizing a series of shafts, joints, and gears, a differential allows two wheels that are attached to the same axle to rotate at different speeds from one another. When the wheels of a vehicle are at different speeds, their rotational speeds will be inversely proportional to one another due to the differential.
Differentials can be attached either to the rear axle of a vehicle or the front axle of a vehicle. Where a differential is located depends on the drivetrain that the vehicle uses, among several other factors. Many vehicles use a rear differential but there are three types of differential categories that are based on the mechanics of the differential rather than the location.
Differentials can either be open differentials, limited-slip differentials, or torque-vectoring differentials. Torque-vectoring differentials are one of the latest upgrades to differential technology. Torque-vectoring differential systems use information gathered from the computer and numerous sensors on a vehicle to adjust the speed of the wheels. Contrary, open differentials are the first type of differential technology and use gear mechanics to transmit power between the wheels of a vehicle. Limited-slip differentials, like open differentials, use gears to provide traction to slipping wheels. However, limited-slip differentials utilize a clutch system to prevent power from completely being transferred from one wheel over the wheel that is slipping.
If you hear sounds coming from underneath your car while you are either accelerating or decelerating then it may be time for a rear differential service to be done on your car. It is important to keep your rear differential well-maintained and lubricated to prevent it from developing permanent damage. Most of the signs that your differential needs to be serviced will happen under conditions where you speed up and slow down. Aside from sounds, if you notice increased vibrations as you speed up or decrease vibrations as you slow down, your differential may need to be serviced as well.
Servicing a rear differential is usually as simple as adding lubricant to it so that the gears and shafts have adequate lubrication between one another. Avoid causing an even more complicated and expensive repair by routinely servicing your vehicle according to the recommendations of its manufacturer. At Deery Brothers, we are here to help. We want to provide our great service to you and keep your vehicle on the road for a long time. We are experienced in servicing rear differentials in addition to a variety of other auto parts.
