Rattle noise underneath vehicle

[Saker]

There is no pop rivet, 6M nuts holding that shield on body studs.

Ahhh, ok.
Kinda looked like it was. May be an easy fix then.

Get some JB weld and cram it on the studs where the hole is wallered out. Will keep it from rattling until your ready to remove or replace.
