Mine was built end of october and delivered end of november, so I'm assuming it has what they claim is "MIC 2.0" it has definitely has this rattle/pop right over the driver's head. I'm going to try this foam solution.
I don’t have my bronco yet but the size looks to about the size of a washer for a garden hose. Try those .The two door loaner I’ve been driving with a MIC 1.0 top has an annoying popping/rattling sound coming from the latch area just above/behind the drivers head (also happens to a lesser degree on the passenger side as well.) Hard to know if this is the same bothersome sound experienced by others here, but I would imagine its not unique to only this vehicle.
I’ve narrowed down the source to the interface between the rounded off pin in the roof panel and the hole this fits into on the painted bracket attached to the frame. I took a one inch square piece of 1/8” thick EVA closed cell foam (aka craft foam) and after unlatching at all four points and lifting the section of the top, I placed it over the hole and under the pin. I then let the roof panel puncture the foam by latching the panel back down. The attached photo hopefully helps to explain. After doing this at both the driver and passenger side, the popping/rattling are completely gone. I’m not sure if the bit of foam protruding down into the hole is what fixed it, the portion of the foam that isn’t punctured, or a combination of the two. I will definitely be experimenting with this further.
Who knows how long this foam will hold up but I think it’s a good starting place for finding a permanent solution to this problem. I’d be interested to know if this is something that has been addressed with the MIC 2.0.
Hopefully someone finds this useful.
UPDATE: 11/20 I’ve utilized this method to eliminate the MIC noise in two different Broncos, including my own. I’ve removed the roof panels and re-installed the original foam pieces when re-installing five or six times now and still having no rattles or pops coming from the top. As easy as it is to just hold on to the foam pieces and re-install and as well as it works, I’m fine with this being the long term solution at this point. I may try experimenting with using some heavy duty 3M double sided tape to permanently attach the foam.
I have a mic 2.0 that had same issue on rear driver side panel. I put a 1” square piece of 3m double sided tape next to the alignment pin leaving the red adhesive cover on the panel side of the tape. Rattling stopped. The 3m tape is a little thinner than the foam you described but I think I will put a thin film of rubber or neoprene on the top of the tape and see how that works.
Good idea, let us know how that works. Hopefully Ford will make a new pin and or grommet to fix this problem.
Great to hear!Got my “mic2.0” delivered on 12/05.
VERY annoying rattling started a little over 500miles in and once temps dropped a bit (seems consistent with everybody else)
The craft foam worked like a charm!
200 miles with it so far and no more rattling.
AMAZING!
