Have only had my 2007 ranger since July but now getting a rattle or creaking sound in drivers door. Just wondering if anyone else had this problem. Didn't take it to dealer yet but wondering if it could be a misaligned latch, loose part, or just a result of colder weather and plastic parts.

 

could be the infamous ranger/Ford vehicle rattle. I.e., we can't put plastic on plastic without a rattle. Or it could be like me having a rattle in my passenger side suicide door which turned out to be a spare retainer for the door modeling that was tumbling about.
