I have a ford taurus and for the last 2 winters I have been in complete fear of driving in the winter. one little bit of snow on the road and my car is all over the place like it is gonna go off the road. whatever is wrong is making my back tires bald and when I drive over manhole covers the whole back end is all over the place! Please help I have had the car checked twice and they keep telling me there is nothing wrong!
