The slightest movement of the steering wheel causes a loud squeeking noise in the undercarriage. I stopped by Firestone to make an appointment and they told me that newer cars like mine (actually it's 14 years old) no longer have grease fittings. Does that mean I will need to replace parts? Have any idea what the cost will be? The car only has 74K miles on it and it seems to me that it should not need replacement already. I can make it squeek by pushing down on the fender while parked.Does that mean anything?
