I took the drivers door off recently to polish the hinges and replace the securing bolts with Stainless. The hinges on my 2009 car are heavy die cast stainless and the pins a very tight fit.
After 5 / 22,000 miles years the door hinges are without any free play. If I try to lift the catch end of the door there is no free movement, the car rocks on its springs.
BUT just checking the bolts isn't enough as the bolts into the door are not captive, so can seem to be tight when they are not. To be 100% cetain you have to remove the door trim card. Not difficult, just a few screws.
