Drain the Honda rear differential fluid according to the service procedure. Refill the differential housing using the correct type and amount of differential fluid or gear oil.

The rear differential contains components known as spider gears that allow the wheels to rotate at different speeds when turning. It also has a ring and pinion gear, which converts torque from the engine through the transmission and driveline into right angle torque. This is what enables the wheels to be driven by the engine. All of the gears and bearings in the differential are submersed in differential oil to project and lubricate them. Differentials create heat under normal driving conditions, which can eventually break down the fluid, causing its lubrication properties to deteriorate. This condition can lead to total differential failure and an expensive repair bill.

Proper service of your Honda rear differential fluid will make sure that the gears and bearings inside have the lubrication they require. With regular service, your differential can last the life of your vehicle. Changing the Honda differential fluid as part of a scheduled maintenance program will enhance the reliability of your vehicle, and save you money during the life of your vehicle.
