What is examined regarding the vehicle’s differential?

The examination of the vehicle’s differential focuses on leaks and lubrication levels because the differential is a critical component that allows the wheels to rotate at different speeds, especially when turning. Proper lubrication is essential to ensure smooth operation and to prevent excessive wear and tear on the gears inside the differential. Inspecting for leaks helps to identify whether the differential is properly sealed and whether it has sufficient lubrication. Insufficient fluid levels can lead to overheating and severe damage to the differential, potentially causing it to fail completely. Therefore, monitoring the condition and levels of lubricant, as well as checking for leaks, is a key part of vehicle maintenance and safety.
