What kind of gear oil goes in the differential?
The construction and maintenance of front differentials mirror that of the rear on the same vehicle. Most differentials call for SAE 75w90 gear oil, however some heavy-duty and limited-slip differentials need SAE 75w140 gear oil. Consult your owner’s manual for the proper weight oil to use.
What type of differential oil do I need?
Use the highest-quality gear oil you can afford to fill the differential. The weight and capacity will be listed in your owner’s manual; your differential will usually hold as much as 3 quarts. Be sure to read that manual, though, because some limited-slip differentials require a secondary friction-modifying additive.
