My doors -drivers door especially, also had that 'clanking' sound and feel to them.
I replaced the door strap on the drivers door yesterday and it's like new! The feel when opening and closing is great. And it's got the good old expensive-sounding 'thunk' back.
The part is only around $16 (in Europe) and it's a real easy 30 min DIY job. Description in DIY section here
