I looked over the excellent posts and pics about removal of the front seatback/headrest. But my question is about diagnosing a rattle. In my case, only on the passenger side. It seems like the headrest has some "play", but it's not obvious to me, from the pics of the mechanism, what would be causing the rattle. Is the headrest post just loose in it's mounting track? I'm trying to figure out if this is something I can troubleshoot without having to remove the seatback. Seem to rattle less when the headrest is all the way down, but it still does it. Driver side is silent. It's a 99 E300. Anyone with 1st-hand experience care to comment?
thx
