I just noticed this yesterday. My driver's side door seems to really be "heavy" now. It doesn't swing open/closed as easy as it used to. It doesn't make any type of noise and nothing unusual has happened to the car. Do I just need a lube job?

 

Unless the car is mysteriously gaining weight then you should just use some WD-40 on the hinges.

 

 

Mine did the same, i had to grease up the hinges and there is a flat rod that goes into the door that helps hold it open and keeps it from slamong shut. That will need some lube. Lube it and open and close abunch of times and relube it.
