When i was coming home last night i heard what sounded like my right front tires "squeal" when i turned left onto our street. I thought i was just hearing things and didn't think much about it. So when I go to turn left into my driveway I heard it again and the steering felt sluggish. So i back up and go get my wife to look while i do it again but this time it just would not do it. So what could cause this and what should I look for?
