I have a 2004 Ford Focus ZX3, 2.3L Duratec engine, 5-speed MTX-75 transmission with 118,000 miles. When I enter and make quick turns in parking lots I hear a groaning noise coming from the front of the car. The tires are wearing normally. The car comes up and stops when either the front or rear bumpers are depressed. What is the trouble and about how much should I expect to pay in Northern California for repair? I can change my own brakes and service the oil. Is the repair of a skill level I can do myself?
