Ya, i put a bottle of the sure grip additive in there. I started pulling the unit apart. 0.008" of backlash. I think the pinion nut started backing itself off. It was only reading 7.5 inch pounds. Since they were new bearings, i think i had it set up at 25 inch pounds. I'm gonna pull it all the way apart and check the cross shafts and spider gears. If all is good i think i might chalk it up to not tightening the pinion nut enough and reassemble.
