Driving me Nucken Futz!!!

A trim in my pass. door rattles every time I'm low RPM. I nearly punched through the door trim once but did nothing to fix it.

 

Maybe Im just deaf from listening to loud music my whole life, but I dont ever hear noises.. lol Plus theres no squeak a loud radio wont fix...

 

I noticed a rattle in my 2010 by my head and found it to be the headrest. I just give it a tap when it starts up.

 

Chris4x4,
Any tips on getting the interior panel off to get to the seat belt retractors?
Must be some simple trick access but not obvious to me.

What are you trying to suggest???

 

I have this same issue. I've tried sanding and putting tape on the buckle where the belt loops through. STILL does it.
