Chirping noise from car when turning

Hi.

I have a subaru impreza 2006 with about 100K miles on it and it makes a chirping noise–which i think might not be coming from the engine or the belts because i had the belts, transmission and stuff all replaced about 8 months ago when i got a tune-up–but i dont know.

The sound most of the time usually happens when i am making a left turn(but sometimes happens while going straight but never in reverse or right turns) while accelerating from a complete stop. However when i take my foot off the accelerator while in motion it the sound stops.

This sound occurs maybe 25-30% of the time.

What is going on???

Thanks

Chances are you need a belt adjusted.
