Anyone having this heatshield rattle when closing the rear deck lid or back doors? Mine has rattled, then fixed by the dealership only to rattle again later. I should get under there myself to look but figured I’d ask here first just in case someone had dealt with this and has a quick fix.
Noisy heatshield between spare tire and exhaust

Yes I’m sure, I can pound on the floor of the rear storage area and produce the same noise, I’m certain it’s the heat shield.

It's a 4th gen, not a 1st, it's probably an easy fix. Get it to someone who's experienced and fix it. I've posted this before, find a shop that has the Snap on audio ears that can be placed around underneath of vehicle. Then the tech can pinpoint where the sounds coming from. Easy, peasy.

Lol for real. It’s not even that annoying, I just hear it occasionally and that’s all it takes for me to obsess over it.

The service techs at my dealership are really good and have isolated and remedied it twice already but it’s returned. I’m just wondering if it’s missing some washers or vibration gasket or something.

Artie, your a Lincoln guy like me. We like quiet, and we like perfection. Nothing wrong with that. When I worked on and rode Harley's, I always took home a totally stock and quiet Electra Glide, or road King. Never liked loud in my vehicles or women. You rarely see a loud doctor or lawyer, or any professional. You want your SUV quiet like when you bought it. To have a 20 year old vehicle behave like day 1, that's Rolls Royce's goal.

That must be why I didn't stay in pre-med Biology major in college!! I'm loud and annoying to most.

You'd have one heck of a bed side manner screaming your an idiot, why didn't you stay on your diet. See, now we did a bypass on you! Yeah, what recovery patient wouldn't want their doctor yelling at them! Ha Ha.

I’m starting to wonder if the heat shield/exhaust setup are the same on the Navi and Expy, especially since no one else has heard anything back there. I promise I’ll get under there tomorrow and post some pictures and poke around.

You could always buy a hunk of that high heat muffler tape or packing, and shove it in there. If your right it should go away. The high heat stuff you should be able to leave in there. Or just re bend the shield, if that quiets it down.

Not a bad idea, I think I’ll try that tape stuff and see how it goes. I should drop the spare anyway just to have done it in a non emergency situation so if I ever do need to change it I’ve been down that path already.

There you go. My 2000 got all tangled up last time I tried lowering it cause of a leaky r/f tire. Better to find out now, than on the side of road. I think your supposed to grease the cable to keep it from getting all jacked up. I got a used cable assembly about 5 months back off eBay. It's messy enough lowering and raising the spare tire, I don't want to get all greasy too!

This method is actually approved by Ford for fixing converter heat shield rattle. I am not certain it is appropriate in this situation.
Buy a few very large worm gear hose clamps. Depending on the size you can find you might need as many as 8 ! (Home Depot or Lowes has large sizes in the HVAC area.) The reason you need multiple clamps is that they may have to be opened up and "daisy chained" together to reach around both the shield and the pipe. Use 2 sets if necessary.
Converter heat shields have a small "standoff" (bump) built into the shield so that even when clamped in this manner there is an air gap between the pipe and the shield. This is CRITICAL !

Better make sure they're stainless steel or they'll rust out and fall off in no time flat. I made that mistake once on a vehicle and regular worm gear clamps only lasted a couple years in the salty winters before they rotted through.

This is what I did yeaterday, took all of 5 minutes and it solved the problem. There is a bracket that’s less than a quarter inch from that heat shield that was causing the rattle. Thanks for the quick simple solution!!
