ANNOYING driver seat rattle!!

Have had an increasingly annoying rattle that keeps getting worse. I have narrowed it down to somewhere in my drivers seat. It mainly happens when I shift weight when turning. Its like there is something where the seat back and seat come together. I have stuffed towels in between which helps minimally. Anyone have this issue? The anchor bolts to the floor are extremely tight, so it has to be something inside the seat. I can actually feel it if I put my left hand down by the recline lever. I've added foam tape behind the recline spring and taken off the molding that covers up the bottom of the seat bracket to see if something is loose, but cant find anything on the outside of the seat. Still no luck in finding this issue!!

 

well, if no one has had this issue, can someone tell me an easy way to get into the seats "guts"? I have moved my seat all the way toward the steering wheel and lifted up the seat backing, but cant figure out how to really get in there and look and see whats clanking around in the seat.

 

Quite a few have had this issue including myself. Toyota replaced my seat and within weeks the noise was back. No idea what the issue is and toyota can't seem to narrow it down either..

 

I have stuffed some towels into the seat which seems to help out a bit, but the rattle is still there. Was hoping I could get into the seat and see what is is exactly thats rattling in there.
