The differential is the element in the vehicle responsible for the transfer of power from the engine to the wheels. It is also crucial in compensating the difference in the wheel movement when you are navigating turns on the road. In simple terms, when you are making a turn, the outer wheels must turn faster than the inner ones for pace uniformity. The differential allows you to maintain control while the wheels are turning at different speeds. This component has internal gears to promote the functionality and require a coat of oil for lubrication. It is important to change this differential fluid regularly to ensure that the vehicle performs well. Here are some simple guidelines to help you understand changing differential fluid.

Knowing When to Change the Oil

The interval for changing differential fluid will depend on aspects such as the vehicle model and the age of the automotive. One of the most appropriate times to perform this maintenance is during regular servicing of the rear auto axles. Generally, the fluid has to be drained for this service, so it is economical to have the two tasks carried out at the same time. On the other hand, it is recommended for you to follow the manufacturer’s instructions. This endorsed frequency is favourable, because it is tailored according to your exact vehicle model.

Choosing the Oil

There are diverse types of differential fluids in the auto market, so choosing the right product for the vehicle can be confusing. Poor quality oil will lead to continued friction in the internal gears, which can reduce safety when navigating sharp corners. In addition, the poor functionality will lead to eventual or sudden breakdown of the components. The differential module can be costly to repair or rebuild if the damage is severe. Ideally, the best fluid for your vehicle is the type originally utilised in the vehicle. The viscosity of the recommended fluid is selected to match the vehicle’s requirements. If you select a new type, ensure that the thickness rating of the original fluid matches the new choice.

Changing the Oil

You can engage a professional technician, like those at Gearbox Express, or change the differential oil at home if you have mechanical know-how. Locate the differential drain bolt and remove it. Allow the existing fluid to drain out completely and then replace the bolt. Locate the oil-fill bolt and remove it. Use a differential fluid pump to fill the hole until the oil starts to trickle out. Finally, reinstall the fill bolt, tighten and wipe of the oil around the differential fluid case.
