In my 2004 Sienna there was a weld in the door assembly that broke and caused a loud clunking noise when I opened the door. Toyota recently issued a recall for this problem and will fix it free of charge
I have the same problem on my 05' Sienna. My mechanic showed me that it was the door hinge making the noise (soon your window will not open unless door is open). My mechanic said he has seen this before, but Toyota dealer has to fix it. They want $1K to fix, so we are living with it. Toyota is going down hill.
