Ever since I got my car back from the shop(ran into a ditch & tore the boot off of the left front CV joint) it makes this subtle humming noise at about 60+mph. You can only hear it over road noise on smooth pavement, but it's still annoying and concerns me. I kind of sounds like it's pulsating and coming from the front of the car.. can't hear it with the window down. I would be worried about my CV joint but I only drove about 15' with the boot off. The mechanic that fixed it is supposed to be pretty good and he said nothing was bent. I haven't had the car aligned since then; I probably should but it drives perfectly straight.
Anybody have an idea what it could be?
