Ok after my build i have about 600 miles on my truck, fresh motor and rebuilt rear end, the rear is a 77 BB 3.50 open
while i was replacing seals last night on the axle shafts i noticed that the gear oil is looking pretty metallic colored. The oil itself looks like dark silver metallic paint (if you mixed it you know the color effect i am talking about) and the sludge in the bottom of the axle housing (yea sludge already....) comes out looking like anti-seize with some metal pieces about the size of a grain of sand. My dad and i had never set up a 9in before but we bought the kit and all the tools and went by the book for setting it up and it all checked out fine. i don't see any excessive wear on the ring or pinion, the bearings all seem good, and there is no excessive backlash. I am thinking of taking the third member into a drive line shop just to see what they say, but i wanted to know what is normal break-in for a rear end. Thanks
