Sunroof Issues on '08 GX 470

[Azarmorer]

The sunroof on my GX 470 has been noisy for awhile now but seems to be getting worse. I was on a slightly washboard road the other day and it was awful. Rattles like crazy. So bad that I'm afraid to really take it offroad. I tried to see if I could find screws or anything else that seemed loose and did snug a couple screws but it didn't do any good. Anyone else had this issue and know what the fix is? Parts numbers? Any help is appreciated.

Does it help to pull the inner cover closed as sometimes this secures the glass roof in place
