Replaced front control arm on my '14 Explorer. Had a clunk up there and I could feel it with my feet on the floor. Common issue with the bushing going bad. After doing the driver's side last week, I learned that the reciprocating saw makes the job much easier. Couldn't get the ball joint nut all the way off, so just chopped the stud off below the nut. Driver's side was a 2.5+hr job. Passenger side was about an hour.
