Somtimes at a intersection or when driving slow the whole front end of my car starts to shudder and shake

Time for an inspection at a tire and alignment shop. Could be dragging brake calipers, warped front brake rotors, and worn ball joints are real common on this model. Ford has more than their share of steering and suspension trouble so noises and shakes are nothing you want to ignore. A separated ball joint is all too common and will send you into a ditch or into oncoming traffic. Get 'er checked to be safe.
