Bad sounds from rear
 

HI everybody.

I received my 2013 convertible and find some problem when drove car from port to home.
Car has 53610 mileage and was sold to me from dealer and certified.

Attachment 151787

So problem is when I drive more than 10 miles. From rear wheels I hear sounds when turning left or right only. If I turn on gear it has sound with creak and scratch, but I try turning on neutral gear and scratches stop and has only peep. When drive straight no sounds.

On cold vehicle no sounds. And also we have cold temperature now in town about 7-8F.

Don't have ford dealer who know Mustang. but check suspension and it's like new. Thinking about bearings but it's ok. I don't have idea what the problem is.

Please help with advice.
