What to know about the Differential Gasket:
Your front differential is the device in your vehicle that converts power from the transmission to the horizontal axis. As is the case with most vehicle mechanisms, it requires lubrication, which in this case comes from differential oil. The front of the differential is sealed with either silicone or a gasket to contain the fluid inside, and is bolted in place. If the seal leaks and the fluid are low, you may experience grinding or whining noises from the front and the possibility of differential failure.
Facts to Note:
Front differential gasket seal replacement is included as part of regular maintenance if the fluid is being changed.
Contamination in the differential fluid comes from debris or metal shavings.
How to Fix:
The vehicle is put on jack stands then front and rear wheels are detached. A drain pan is placed under the front and rear differentials and they are drained of fluid.
The faulty front differential gasket ischanged following the removal and installation process detailed in the respective service manual. The front differential is then filled.
The rear differential cover is then removed. The new gasket is installed and the differential is filled.
The tires are reinstalled and the jack stands are removed. The tires are torqued to correct specifications.
The vehicle is road tested to ensure proper operation of differentials.
The differential gasket is changed when the fluid is replaced. If the seal leaks between maintenance intervals and the fluid run out, the differential could be spoilt, and then your vehicle will be rendered useless. If you suspect or are aware that the differential gasket is leaking, have one of your expert mechanics check it out and change it if necessary.

Importanceof this service:
Except you have a huge fluid leak, you can continue to drive your car for a while. However, like all fluid leaks, this needs to be fixed eventually, so you should have it checked by one of your expert mechanics at your earliest convenience so that the problem won’t drag on indefinitely.
