I checked my drivers door and it is solid from moving up and down - no play that way at all, but it has like a half inch of play moving out and back in again. I was incorrect in saying it had up and down motion in my first post. It just seemed that way when i was driving it on a rough road. I think adding the weather stripping will help. But curious if anyone else has had this issue of the door moving out and in, and if rebuilding the hinges would still help with this? Thanks.
