Differential/Gear Oil Replacement
A differential or gear oil replacement service helps maintain the performance and durability of your vehicle’s differential and other applicable gear assemblies by replacing old, contaminated, or degraded lubricant. Differential oil reduces friction between gears and bearings, helps control operating temperatures, and protects internal components from excessive wear during power transmission. Over time, the oil can deteriorate or become contaminated, reducing its ability to protect moving parts effectively. During this service, a technician checks the differential or relevant gear housing for leaks, inspects the condition of the existing lubricant where possible, and drains the old oil according to the manufacturer’s procedure. The assembly is then refilled with the correct grade and specification of gear oil recommended for your vehicle. The technician checks the fluid level, inspects the drain and fill plugs for leaks, and verifies that the assembly is properly sealed. Replacing differential or gear oil at the recommended service intervals helps protect gears and bearings, reduce friction and abnormal noise, support smooth power transfer, and extend the service life of your vehicle’s drivetrain components.
