horrible squeak in my door

2008 trd double cab

My drivers side door makes a very load and annoying squeak when my window is down all the way and I drive over bumps. But then goes away when I roll it up a few inches.

Can anyone instruct me on how to get rid of this? Do you have pics of your door without the panel on? Is it easy to take off the door panel so I can maybe add some grease?

Thanks for any information!!

 

actually check out the speaker installation DYI in the auido video. It shows you how to get the door panels off

 

That's a good idea, I'll check it out.

I took my door panel off, and after much looking around I found the source of the squeek was a loose nut. The one that connects the track the window is in to the door.

Finally I can roll my window all the way down and rest my arm on the door without that dang squeek.
