Rear Drive Oil Black?
4,000 miles ago I installed a new rear drive bearing (17 ball bearing) and new seal along with the o-ring and 2 new bolts. I replaced it to make me feel good. I changed the oil (Mobil 1 75w-140) at 500, 1,500 and yesterday at 4,000 miles. All three times the oil has come out a light black in color. Has a little black slim around the drain plug, which is normal. No metal on the magnet.
WHY IS THE OIL COMING OUT LIGHT BLACK IN COLOR? Before I changed out the bearing the oil always came out looking like new.
