Every time you corner, you put the differential of your vehicle to great work. It has to supply the drive wheels (left and right) with a separate amount of torque since the wheels do not spin at the same rate whenever your vehicle turns-the inner wheel spins more slowly while the outer wheel spins faster. For the differential to work efficiently, it has to have parts in excellent conditions. Most importantly, the differential bearing must work well. This bearing is the part employed to keep the differential gears properly aligned. It also reduces friction among moving components in order to preserve the life of the said parts. While doing all these, the differential bearing should also put up with the weight of your vehicle. Given the right conditions, the bearing is able to handle all the stress as long as it's properly lubricated. There are instances, however, when the bearing is damaged. Improper installation, overload, and oil contamination are just some of the causes of differential bearing failure. If you notice that your car's stock bearing is already damaged, find a replacement at once. We at Car Stuff have a wide array of differential parts, and finding a good differential bearing should be easy. Check our catalog today.
