Understanding the Role of Transfer Case Fluid
The transfer case distributes power from the transmission to the front and rear axles, allowing your vehicle to operate in different drive modes. This intricate system relies on the transfer case fluid to function smoothly. The fluid lubricates the moving parts, reducing friction and wear. It also helps dissipate heat generated during operation, preventing overheating and damage.
Just like transfer case fluid, power steering fluid also plays a vital role in your vehicle’s operation. Learn more about its ideal color in our article on what color is power steering fluid supposed to be.
