In the 2014 Ford F-150, the rear differential requires SAE 75W-140 fluid. It's crucial to maintain the proper level of oil in your rear differential as it is the last set of gears the power passes through before reaching the wheels. The oil for the rear differential needs to be thicker than the one used in the engine due to its smaller size and tendency to heat up quickly. Using thin oil can cause faster wear and may ultimately damage the gears, so avoid using it in your differential. Regularly check for leaks and promptly replace seals if you see any signs of oil leaking out.
For a 2014 Ford F-150, you'll want to use 75w140 fully synthetic fluid in the rear differential.
