The differential fluid is responsible for lubricating the gears and bearings in the differential system of your vehicle. Over time, it breaks down, becomes contaminated, and loses its viscosity, thus losing its effectiveness. If the differential fluid is not changed regularly, it can lead to significant damage to your vehicle’s differential system, including excessive wear on parts and permanent gear damage.

Causes of Differential Fluid Breakdown

Differential fluid plays a crucial role in ensuring the smooth operation of a vehicle’s differential system. However, over time, it can break down, leading to a host of problems such as gear wear and failure. Below are some of the leading causes of differential fluid breakdown:

  • Heat: High temperatures are a leading cause of differential fluid breakdown. When the differential gets too hot, the fluid starts to break down and lose its lubrication properties. This, in turn, leads to increased friction between the gears, causing wear and tear, which, if not addressed, can lead to complete system failure.
  • Water Contamination: Differential fluid is susceptible to water contamination, which can cause the fluid to break down prematurely. This is particularly the case if you frequently drive through deep puddles, streams, or any other areas with standing water. Water contamination in differential fluid leads to rust and corrosion, which can cause damage to the differential system’s gears and bearings.
  • Age: Differential fluid, like any other type of fluid, has a finite lifespan. Over time, it will start to break down and lose its lubrication properties, making it less effective in protecting the gears and bearings against wear and tear. Generally, differential fluid should be changed every 30,000 to 60,000 miles to ensure optimal performance.

Regularly checking your differential fluid is essential to prolonging the life of your vehicle’s differential system. Also, be sure to address any issues promptly to avoid costly repairs.
