Re: IMPORTANT: Changing front differential oil
The factory manual specifies the fill level to be 1/4 inch below the fill hole, or else aeration of the fluid will occur. When gears run at high speed, the gear oil foams if you fill it up to the fill hole level. Gear oil is not compressible, but bubbles are, and direct metal to metal contact results, and bubbles act as an insulator so higher temps / oxidation of internal metals is accellerated This applies particularly to the Mopar fluid with friction modifier, while higher quality synth. fluids have less tendancy to foam, e.g. Mobil 1, Amsoil.
