First of all, thank you for the video. Then, according to you, for a normal use (not extreme), what is the frequency of change of the differential oil. Is it the same as for the engine oil: minimum 1 time per year? Or is it possible to stretch the frequency?
On the SmartLok there are several. One for the rear and 2 in the front diff to sense slip and lock the front end. For the non SmartLok it’s on the driver’s side of the rear trans.
