Differential fluid, a lubricant essential for the proper function of a vehicle’s differential, requires periodic replacement. This fluid reduces friction and wear between the gears within the differential, enabling smooth power transfer to the wheels. An example would be changing this fluid every 30,000 to 60,000 miles under normal driving conditions or more frequently under severe conditions such as towing or off-roading.
Maintaining the differential with fresh fluid is crucial for extending its lifespan and preventing costly repairs. Deteriorated fluid loses its lubricating properties, potentially leading to increased friction, heat, and eventual gear failure. Regular fluid changes ensure optimal performance and help prevent premature wear on differential components, contributing to the vehicle’s overall reliability. Historically, manufacturers specified longer intervals; however, modern vehicles and demanding driving styles often necessitate more frequent servicing.
