for a while my car has made a clanking noise when i shift or accelerated from stop sometimes but from looking at other forums it sounds like it happens to a lot of cars and dealerships are discouraged from fixing the problem because it is so common or something....recently my car started making a popping noise when i accelerate or when the car seems to be under some stress (hills, trailer, etc) does anyone know what the problem is? i'm guessing its either the u-joint or cv-joints...hopefully the u-joint. any ideas would be helpful thanks
