loud squeak when turning left
 

I get a very loud metal-on-metal squeak (continous) while turning left, especially while maintaining or accelerating. I know that the first answer is bad axle bearing, but I just changed them 2 months ago along with the seals. I also just got my car back from fixing my differential. The obvious answer is to take it back, but I don't trust the guys who fixed my car. I am hoping it could be something I could fix and avoid the scam artists that had my car. What could cause the squeal? I think it starts when the limited slip disengages. Doesn't do it when I turn right. But is extremely loud and embarrasing. Could it be the axle? Mabye slightly bent or something?
