lower control arms

my front wheels are tilting inwards could that be my control arms and if it is where could i find some for cheap and how much should i exspect to pay for a mechanic to fix it?

Is your car lowered? That's a camber ( / or \ tilt of the wheels) problem.

My left from tire was doing the same thing, and I took it to the dealer and they replaced my a-arm, it was $180.. not sure if that is what is wrong with yours, but that sounds like what mine was doing
