You need to have the front Lower Control Arms replaced. When they start to go bad it is intermittent. As the service manager at the Ford dealership I go to explained to me, Ford switched from rubber to hydraulic bushings on the control arms. As they continue to get exposed to heat, they start to go bad. So as they heat up, you will hear squeaking. Eventually, the heat will take it's toll and they will just be shot.
With 2K miles mine are just starting to go bad, they only make noise once I have driven for a while and they get heated up. But soon they will just be shot. They are replacing my LCAs on tuesday.
I see a recall in the near future...
My wheel bearings also went bad at 1K miles! I love my Mustang, but I can't believe all the bad front end parts on these brand new cars!!!
