Flapping Sound from Front Driver Side wheel Well Area

I have a 2013 Sahara Unlimited with 19,000 miles. Ever since it was new I've had a flapping sound coming from the left front wheel well area. The noise starts at 70 mph and sound like a piece of paper flapping in the wind. Gets even louder when I get behind an 18 wheeler above 70mph and pick up his wind turbulence.

At first I thought it was in the Dash area, but then determined it was closer to the floorboard or firewall. Then I though it might be the plastic wheel well hitting the body of the Jeep since I can move the wheel well around and it has a lot of play (all the screw bolts are tight).

Then I looked up behind the wheel well and notice what looks like a heat shield or sound deadening shield not tight against the firewall. There are two welded screws coming of the firewall thru the shield without any washers or nuts on them. (See pic).

Should the welded screws have something on them to hold the shield tight against the firewall? Also should the plastic wheel well be able to move around or should it be tight?

Hate to have the dealer keep my Jeep for two days to tell me that's the way it should look and the wheel well movement is normal.

Thanks for the help

Greg

Put some nuts with big washers and see if it stops(use fender washers)

I have no idea what I'm looking at in that photo. Probably why the dealer said it looks normal.

But really... Wheel well movement is normal? WTF is that?

Gonna go with this. After I cut my stock fenders and removed the liners, no more flapping/tapping in the driver foot well area.

Mine doesn't have any nuts on those either, I keep meaning and forgetting to put some on, but I haven't heard any strange noises from there yet.

I believe they are an M6 nut.

The picture is looking upward from under the Jeep (Driver side) at the firewall. According to my dealer it is sound insulation and each of the screws welded to the firewall should have a push-on stainless washer to hold it firmly against the wall.
