Hi. I'm new to this site. I have a 2007 Mustang (Grabber Orange) with 66,000 miles -- during routine maintenance (oil change) at the dealership, was told that the lower ball joints need to be replaced. Is this something that usually gets replaced at 66,000 miles? After I started questioning the service adviser, I was informed that it was an oil change technician that noted the problem and that I should bring it back for them to really look at it (cost: $105 to look) and then if they needed repair it would be $300 for the parts and $900 for the labor! Is this something I should take outside of the dealership? Is there something I would feel/hear when I'm driving the car? I love my car but it seems Ford has had plenty of issues .... specifically with mine the front hood paint had to be repaired (at my cost) due to early corrosion, water leaking into front passenger cabin, electrical problems caused by the rear defroster, etc.
