Moaning/Grinding Noise

[masterpete]

From a stop if I accelerate slowly I dont hear anything, but if I accelerate kinda fast theres this grinding/moaning noise coming from what feels like the drivers side, like right under my feet. Took it into the shop and they said they didnt know. I love automotive repair facilities......hahahaha

Thanks,
Pete
