Assistance/ideas needed with creak/rattle noise behind instrument panel.
Lubed up the steering shaft and new grease around shaft boot.
Also, removed the panel under the column and insulated everything I could see. Removed cowl panel under the hood and insulated all hard lines that seemed like they could make noise by the brake booster.
Per suggestion of another member here, lubed up the inner wheel housing splash guards where they meet the fender.
Still, have this persistent creak/rattle. Does not seem to be suspension. Sounds like interior.
Probably more prominent on roads that put the chassis into torsional load rather than hearing it over bumps, which makes me think it's at a mounting point of something more rigid than what it's mounted to rather than something loose.
Any suggestions on things I can try other than a molotov cocktail?
Thanks!

What happens is the felt applied to the panel comes in contact with the clear plastic HUD lens and slightly dampens it or adds a bit of pressure to it so it will no longer rattle anymore.
PS I did have to revisit the felt ONE more time about 10000 miles later to add a bit more because the noise came back slightly but that has been about 40000 miles age.
I'm going to pull out the instrument panel and see if anything reveals itself.
Removed the cluster, insulated everything with self adhesive felt and foam. -No change
Took off panel on firewall behind engine, found heater control valve tapping on firewall, insulated -No change
Started looking at other areas and the noise while sounding to me like coming from the center of the dash was actually the storage compartment at the front/lower drivers seat.
Lubricated the latch and hinges, added foam underneath end cap that clips on = no more thoughts of parking it on train tracks
