Help Please, front door hindge rattle

[RojoGray]

Please help! Around the driver side top door hidge I'm hearing a high pitch tingy rattle. It's difficult to reproduce or determine exact area. Sounds like small metal balls in a can, hollow sounding. It seems to be from the area of the door hindge but could be between fnt quarter panel and firewall. It's been to shop 3 time for a total of 10 days. They found a broken window regulator??? whatever that is and they fixed it. They replaced the whole door panel with all associated plastic worn attatchment plugs and double check all wire and parts inside panel. I have checked all wires and cable I can get access to from under hood and under carriage. They did turn rotors, replace brakes, replace belts all before I noticed the rattle. The Tahoe is in perfect shape with 61,000 miles. Ideas??

I'd look into a door hinge bushing.
