Rattling Sources

It's road construction season where I live. If there's a lose part anywhere in the interior, now is the time of year I'm going to hear it! I've been chasing a toy-like rattling sound coming from the windshield area. I thought it was the defroster vents at first, but it wasn't. One rattle was coming from the radio bezel. I pulled that apart, snapped it together, and the rattle disappeared.

Another rattle persisted. I took apart the rear view mirror plastic assembly, snapped it back together, and nothing changed. I next realized the rattle was coming from the ceiling console. It would rattle even if I didn't have my sunglasses in the holder. I thought I broke it when I pulled the plastic cover away from the headliner... it took a lot of muscle to fight the clips. Everything was OK up there, except the pictured T20 torx screw. That loose screw was wiggling around nearby plastic causing the rattle. I never would have thought one screw could cause that much noise! I tightened that, and snapped the console back into place.

If you find yourself chasing a rattle, try using a sine-wave signal generator app. Route the audio into your radio, and scan up and down the low frequencies with the volume up high. Once I found the "sweet spot", the rattle I was trying to find would vibrate like crazy, and I could easily identify it's location. I found that method much easier to manage rather than trying to figure it out while driving.

I'm looking forward to a reasonably rattle-free ride into work tomorrow

Re: Rattling Sources

Any recommendation on which app to use?

I have been chasing rattles for a few weeks now. One source I have found is the doors. I adjusted the jam latch to tighten them up a tad and it helped. There is only going to be a tiny amount of adjustment available, but it was enough to get rid of some of the more irritating creeks when the body would flex when turning.

I use Signal Gen from Media Punk for iOS

Yup, I've noticed that the plastic door trim will rattle if I have the music up loud enough! I wonder if I can replace them with the wood inserts that come with the summit
