The white is the gear pattern, ran out of yellow so had to use white non hardening/drying paint. Any good advise is appreciated. I used the pinion shim that came with the pinion gear and got preload set to 20 in lbs, got the carrier bearings set at .000, but not preloaded yet, backlash at .007 and carrier bearing caps torqued to 65 ft lbs. All within GM specs. Thanks for the input guys!
