I have a couple of near heart stopping incidents when making a right had turn and having the door fly open. Fortunately there is a steering wheel to hold on to but the first time it happened I was totallyunprepared and was halfway out the door.! I now drive with the door locked but still worry about it. I have lubed the door latch mechanism with Kroil and cleaned all the built up gunk on it but there is little to no improvement (it does lock easier). When I shut the door, even slamming it, there is some amount of movement in and out, maybe about 1/16" All my door rubber is original and quite ragged and I don't know if that would help but think that the latch is just not doing its job. Any suggestions on how I might fix this?
