Post new gears break in

should they make alot of noise at first? they dont really make much or any noise when there is a load on them, only at the point where the engine and the drivetrain are spinning but with no drive or cost load. what do you think? it makes a high pitched whining noise. my old gearset did but not this intense.

I've been told certain gears are more noisy than others,did you brake the new gears in properly by running them easy for about 20 minutes,letting them cool down completely doing that 3-4 times before hard starts? gear lash set properly?

I have been running the break in and the first time the noise concerned me. it is a high pitched whine and its loudest at around 45 with no load. I can feel it though the car. I used the old shim new bearing and I came out with a bad pattern on the teeth so I swapped the carrier chims side to side and it gave me a pretty consistent pattern in the center of the teeth. I know what the pinion depth is all about but never understood what backlash is, could you explain?
