Differential fluid reduces the heat caused by the friction of moving parts inside the differential. But friction and heat will progressively break down differential fluid. Worn-out differential fluid can lead to unreliable differential performance, noise, excessive wear, breakdown, or failure. Complete differential failure will result in your entire differential system needing to be replaced. Always be sure to refer to the owner’s manual in your vehicle when determining the proper service intervals for changing your differential fluid. A differential fluid service prepares your vehicle for new fluid by draining out the old fluid and replacing it with fresh differential fluid. During a fluid change, our service staff may inspect other differential components, like gears and shafts, for excessive wear so that the differential continues to work properly.

Heat from friction will gradually cause the differential fluid to break down, making it harder to keep the differential properly lubricated. Degraded differential fluid causes poor differential performance, excessive noise, and disproportionate wear. In severe causes, old fluid will eventually cause a differential breakdown, if not a complete differential failure, which means that your entire differential system will need to be replaced. Replacing an entire differential system is costly and can be avoided with routine maintenance as indicated by your owner’s manual, which will provide you with specific intervals for servicing your differential. Depending on your needs, when you undergo a differential service, various components of your differential system will be checked and possibly repaired or replaced in order to keep your vehicle running efficiently.
