Fixed Vibration / Rattle in Rear Interior Area

[Sheriff]

Ever since I pruchased my used '06 (mid December), I noticed an annoying rattle coming form the rear interior area. It only occured after the engine has warmed up a little and at idle (slightly lower RPM after warm-up). Did a lot of searches here and other locations, but nothing came up that was similar to my situation.

Yesterday, I installed my new Magnaflow exhaust and during the process had the H3 idling (enjoying the new exhaust sound ) and heard the rattle, so the search was on. After a little time I realized it was coming from the jack storage area. However, nothing that I did to tighten the jack (even shoving towels around it) would eliminate the vibration noise.

I was just about to give up when I closed the back door and went around to the drivers seat and noticed the sound was gone!! I went back and opened the door and noticed that I had left the plastic cover off by accident. I put the plastic cover back on, closed the door, and sure enough the rattle was back. It is hard to believe that such a lightweight cover would cause that much noise, but when I added a little rubber padding around the edges and re-installed the cover, the noise was eliminated!

Thought I would share this in case anyone has a mysterious noise they can't find. Maybe this is unique to my H3, but who knows, this might help someone in the future!!

I'm glad you found it. Thanks for sharing your experience. Talk about finding a needle in a haystack!

Ditto, thanks X2!

Now if you could find that annoying distortion sound emulating from my left rear speaker, at certain bass levels only, we'd be in business....

I'd love to help if i could, but I get total brain shutdown on anything electrical related! From a mechanical side I could probably take my H3 apart and put it back together as long as someone was there to hook all the wires back up!!

It's not electrical, I just have to pull the inner door panel and find whatever's loose. Too lazy and don't trust the service department (dealer) to do it without jacking something up.

Throwing some SRV into the CD with the bass maxed out usually brings out the bone chilling vibration in that door.

the door is easy to pull off. just pry off the cover on the grab bar on the door, remove a couple of torx nuts an pull out the snaps on the perimeter of the door. When your done snap it back on in about 5 or 6 locations with a light tap and put back in the screws and cover.
