I have an 2005 Montego and the past few days it sounds like something is draggin

What is your question?

Sounds like something is dragging under the bottom possibly rear driver side. After reaching 35+ miles you can't hear it anymore until you slow down. Also sounds like the rear brakes are scrubbing, any ideas on what it could be? Balljoints, rotors, etc???

What makes this problem better or worse?

Worse when driving under 35 mph

How long has your 2005 Mercury Montego had this problem?

A few days
