8-3/4 Noise After Rebuild..What's Normal??

Guys, I've been running the car around town, not hammering it, just to get the gears broken in a bit..... the noise is equal on accel and decel, BUT, it whines abnormally (perhaps not for new gears, but I've never heard it before) when you corner tightly from street to street........both directions are equal whines, and definitely in the gearset.....kind of high pitched going around the corner.

BUT..........try to back out of a parking spot, and the gears try to lock up......bumping and grinding........really nasty........not when you back up straight, only when you turn either direction............

I don't think the gears are set up right, but I could be wrong........what's your first impression here from your experience???????

....................this is a good shop that did this.....racers themselves........I'm not sure how to handle this one..........if I just need a friction modifier to start making this slip freely, I'd hate to take the car back and give them a hard time...........................

Help......................:shaking:
