4WD Hub Locking Actuator Delete - Doorman 600-405
Hey,
So I installed these a few months back on my 2015 F-150 FX4. Should I upgrade my front differential oil with 75w140 like the one in the back?
The front has 80w90 oil. But now the front axles and differential are spinning all the time, and at higher speed...
Thanks!
