The trick to making them last a long time is pull the door closed but stop pulling when the door slams shut
Seriously, pull on the handle to get the door moving but let off on the pull as the door comes closed. (just like a quarter-mile race, HAMMER ON and let off
)
Like Hedgehog says, keep the latches and hinges adjusted and like I say, don`t use the arm-rest door pull to pull the door THROUGH the door opening
