Green bearing.. a little noise cruising, a lot of noise on decel.. and back and forth noise when you get that perfect spot between decel and accel.. I have only put 15 miles on it, i figure better than i check it before i ruin something. Saw a video earlier of a place that had bad whine and redid the pinion shims and made it go away. I'm more annoyed that everything single thing on this car has had to be done 2-3 times minimum. And i HATE driving it so far. :) WAHHHHH i'm whiney as my rear end today...
