My front passenger side door takes either a running start
or if you hold it the whole way closed it closes just fine. I've yet to take the time to adjust it, but I got many of the other doors working better by lubing them up with some MB slide grease.
Ok now since it is lined up completely closed, how does it line up before all the way closed? My front door seems to be sagging perhaps 1/8", I just need to readjust the hinges so it hits the right spot. This is what I attribute the closing problem, such as you have to. It would be much easier to readjust the striker on the vehicle, but that means it'd sag that 1/8" all of the time rather than be perfectly aligned like it is now.
