I'm OCD when it comes to squeaks and although the RX is pretty solid, it's had its fair share of annoying squeaks. One squeak I can safely say the source has been found, and now eliminated is the infamous ticking sound you hear by your left ear several have complained about. Now this is a specific sound which sounds like pin tapping on a hard surface
. There are other sounds more like squeaks around the door panel/frame that are mostly addressed by other posts.
So I'll cut to the chase. The source is the tape backing behind the felt material inside the B-Pillar.
Easily reproducible by touching on the felt once you pull out the lower cover.
. Simply pull away the plastic cover from the B-pillar (Pic 1). There's a little force required as there are three white clips (Pic 3) holding the cover into the metal frame of the car. If the clips fall to the bottom, you'll need to remove the driver's sill cover to be able to move the B-Pillar cover more fully outward and gain access to the clips (Pic 4). This is the smoking gun step. If you press on the felt and here the ticking sound, that's the source - proceed to the next steps.
Remove the felt from the cover and remove the tape backing (Pic 2).
Place the felt back, apply 3M Hockey tape (or equivalent fabric-type tape) in some spots to hold it in place. Also, add this tape to the contact points to help further minimizes plastic on plastic rubbing/squeaking. Slide in the 3 white clips back in their spots (Pic 3).
Snap the B-pillar cover back in starting from the bottom moving up. Should snap in easily with minimal effort.
Place the hockey tape on the contact points of the door sill cover (Pic 5) and snap back into place. This requires more careful alignment and slightly more effort to snap back in.
