Me again-
I finally had a chance to read your responses. Thanks for your input. I decided to take apart the calipers and make sure they weren't sticking and the check for suspension slop. I didn't really think there would be slop because my mechanic had just replaced some sloppy components berfore we bought the car from him. But, there was. The brand new A arm inside bushings were both shot on the car's left side. The right side was fine (the bushing also looked better quality too). They only had a few thousand miles on them. I'm not sure what brand they were because there is nothing written on them. So, should I replace the entire A arm or just press in new bushings (I'd like to get the junky A arm out of there though)? And where can I get good quality parts?

I am hoping that my mechanic will step up and make the repairs at his nickle, but I'm not holding my breath (don't ask why).
Thanks
