I went around and found what causes my squeaks and rattles, and used thin foam tape between the parts to keep them from rattling. So far it's worked perfectly (and you can't see the tape if you take your time). My interior is pretty much rattle/squeak free......just need to get some dynamat now and do the floors and doors to quiet things down a bit.
Have one in the dash of my '03 X, never did find where it was coming from. :frown: Recently I've noticed one in my '07... think it's around the head unit... it comes & goes, so I'm still looking for it.
From the driver seat, I'd swear the noise on the '03 X was on the passenger side of the dash, but when my son was with me, he said it was towards the drivers side! To make it interesting, the sound isn't always there! :icon_eek:
