Understanding the Differential and Its Lubrication Needs The differential is a gearbox that allows the wheels to rotate at different speeds while distributing torque. A grinding sensation or vibration during turns may signal advanced wear or a failing differential.
Differential Gear Oil Viscosity Guide: Selection and Importance
It is critical to adhere to the Original Equipment Manufacturer (OEM) specifications, as using an incorrect viscosity can lead to poor lubrication, increased wear, or reduced fuel efficiency. In front-wheel-drive cars, the differential is often integrated into the transaxle.
Heavier gears, such as those in trucks or performance vehicles, often require higher viscosity oils like 90 or 140 to prevent metal-to-metal contact under extreme loads. Corrosion and oxidation inhibitors protect the metal components from moisture and the high temperatures generated during operation, extending the functional life of the fluid itself.
Differential Gear Oil Viscosity Guide Selection
Viscosity and Gear Oil Specifications Viscosity is the primary physical property of gear oil, dictating how easily it flows and how effectively it maintains a film between gear teeth. Furthermore, contamination from water or metal particles can thicken the oil or cause it to appear milky or dark.
