Getting familiar with the group...
I was getting a creaking/tapping noise,just one creak at a time when i went over light bumps. It was not from the impact but fron a flexing of the roof area. I thought I had traced it to the rear dome light but that was cose but no cigar. It's hard to pinpoint by listening to it. It sound like its further back like the sun shade but its NOT THE SUNSHADE. I reached back and pushed up on the headliner just to the right of the rear dome light while driving and it would not creak. I also sat in the back when parked and pushed up hard in that area and could reproduce the noise.What i did to to FIX it was remove the rear dome light and let it hang,then stuffed a large amount of foam rubber between the cross menbers and the headliner,mostly on the right side of the rear dome light but put some on the left for the hell of it. I got some scratches on my wrists sticking my hand up in there and the head liner buldged just a bit,not noticable. I did both front to back and left to right crossmenbers. I also put some above the two plastic tits on the dome ass. befor i put it back in,to keep plastic from touching plastic,just in case. MAKE SURE THE SUN ROOF SHADE STILL OPENS and the foam does not interfere with it,if so jam the foam down fully between the crossmember and the headliner. This put a stop to this sound, it took me like 20 min. I'm glad I did it the noise was driving me nuts. I may have had the only car with this problem but i doubt it,maybe a bad weld. Good Luck
