New gears and alot of noise

Well I guess I misled you all a little, at time of first post I had only had it in the air and it made noise. After I took it out for a drive I had realized it was making too much noise especially on decel around 2300-2800 it was really loud and on accel it was still makin too much noise. I guess I didn't get the depth right (it looked good when I set it up!). I was also told I should check the backlash in more than one place. I will be taking it out again sometime in the next week. I would like to thank you all for your input it was very helpfull!! On another note though my baby sure gets up and goes with those gears!!!
