Changing rear differential fluid is a crucial maintenance task that helps ensure the longevity and optimal performance of your vehicle’s drivetrain. The rear differential is responsible for distributing power from the transmission to the wheels, and the fluid within it lubricates moving components, reduces friction and wear, and dissipates heat.
Regularly changing the rear differential fluid is essential for maintaining its lubricating properties and preventing premature wear and tear. Over time, the fluid can become contaminated with metal shavings, dirt, and other debris, which can reduce its effectiveness and lead to damage to the differential. Additionally, the fluid can break down due to heat and exposure to oxygen, losing its viscosity and ability to protect components.
