Strange noise and can’t find it!!!

[DrWinkler]

Hi guys. Need help on a hard to explain noise. I have a vibrating noise in the back of my 4Runner. Sounds similar as if the spare tire orthe car jack was loose. Sounds no irregular roads and mostly after 30 MPH but does sound at low speed on irregular streets. Just vibrating, metal against metal noise. Not to loud but enjoying. It disappears if it’s rainy!!! Already changed the Drive Shaft U-Joints. Even got my daughter in the back to hear where it comes from. She points to the differencial. Open to all suggestions, please!!

Buy cheap frs radios. Tape one to key always on. Zip tie to various places on under carriage. Keep moving to isolate the noise.

What condition are your rear LCA bushings in?

Thanks for your attention. Also thought it could be there. Mechanic checked them and said all bushings in the back are in good condition.

Thanks for the suggestion. Sounds crazy but interesting. Wish I could strap a GoPro too.
