At around 300 miles in, my Bronco has developed a pretty gnarly rattle from the tailgate.

I will try to get a recording, but it is very loud and easily reproducible by driving basically any distance.

I had someone ride in the cargo area and they said it’s coming from within the tailgate itself, like metal pinging against metal. Not near hinges, latches, or where the tailgate interacts with the hard top window seal. I popped the accessory ready cover off on the inside of the tailgate and there are only some small holes into the interior of the tailgate, so no way to reach your hand in there or anything and it’s unclear how it could be disassembled any further, given it’s metal sandwiched together.

Ford dealership service departments around here aren’t rated well at all, and since they likely haven’t troubleshot many/any Broncos yet, I’m thinking about waiting and continuing to see if I can remediate before asking them to deal with it. Not sure how long I can go though, because it’s VERY loud!

Anyone with service manuals able to provide any insight? Is there better access from behind the spare tire? Not sure I would feel comfortable doing much more myself, but if there’s a quick and easy way in I may give it a shot..:
Hey, try using compressed air a flex magnet. Also, tape up some tubing to your shop vac and go fishing. Goodluck.....

This is not a normal Squeak or Rattle. It is BAD.

Feels like the swing gate is coming apart over rough pavement.
I have the same thing, just like the vid posted. It’s no big deal.

Reporting what worked for me in hopes it will help others:

1. I developed the same rattle as in the short videos posted on this thread. Noticed mine 2-3 weeks ago, at about 500 miles.

2. After reading another thread on B6G (but not this one) regarding a rattle from the cargo area, I applied GummiPflege to all window and seals in the rear. This didn't resolve the issue.

3. Rode in the rear seats yesterday morning and I isolated the sound as coming from inside the tailgate as others here observed.

4. On advice of a poster to this thread, I removed the rectangular black accessory cover from the tailgate and really doused (bathed) the 2-3 bolts that I could see with WD-40 Spray Lithium Grease. Test drove it again and the noise was better (i.e. less frequent) but still there. Figured I was on to something.

5. Found and read all 13 pages of this thread. I removed the accessory cover again and doused the lower bolt towards the driver side latch that I had missed on the first pass. (Tip: Use flashlight to see this and all other bolts to make sure you don't miss any).

6. At the same time, on the advice of another poster to this thread, I doused the latch mechanism on the tailgate and the slider on the body.

7. Test drove again and the rattle/tick-tick sound is completely gone.

Not sure what actually resolved my issue or whether it was a combination of all these things but I hope this helps others.
WD-40 spray lithium grease worked for me. This metallic/ticking rattle was driving me crazy. Took into dealer to make some adjustments on the tailgate/hardtop per the TSB that Ford has on this. They suggested not doing that but did take the hardtop on and off. Suffice it to say that didn't work. Also tried the weatherstripping and lubrication on the tailgate lip where it meets the back window. No luck there. Finally sprayed a lot of WD-40 spray lithium grease into the small access slit in the lower passenger side. I could hear a tick/click from this area when I opened and closed the tailgate. Let it sit overnight and took for a ride the next day and this rattle from hell is gone. :)

The OE spare tire carrier does have a rattle to it which reverbs throughout the cab, but it only starts doing that when the road gets bumpy..

The most annoying sound. It is random and cannot be replicated when stationary. Only hear it on rough roads. Seems like it is coming from inside the tailgate and kind of sounds like it is stretching sometimes...

I have the same exact noise coming from my 2 Door. Started at about 200 miles and has been doing it ever since. Do you still have the stock tires on? I swapped to a tire that’s 15lbs heavier so I thought that might be causing it. Looking at the other pages in this thread, it seems it might be the wiring harness, not the spare carrier itself.

Yes I am on stock tires still. Mine started around 1300 miles. I just tried the WD-40 hack people talk about in this thread today and I'm letting it sit. I hope it will be gone tomorrow.

I've done the WD 40 hack as well, lubed everything up, let it sit and still rattling. GRrrrrr

It seems like it worked for me! Not sure If it's a permanent fix but I didn't hear it when I drove this morning! Make sure you don't skip any of the screws...

That actually sounds like the spare is loose!

I have a noise that sounds like zippers rattling together... Maybe not the tailgate itself, but definitely in the back.... Over bumps but not every bump.
Behind the side panels or in the tailgate. I have not back seats or floor!

My rattle was one of the two rubber spacers at the bottom of the spare tire. The screw is stripped and whatever is on the backside in the tailgate holding that screw is causing the rattle. Now I am trying to figure out how to secure it. When the spare is off. No rattle.
It isn't a screw that holds these.... Just plastic push pins like what you see on the fender liners.

Hey...cut Ford some slack...they rushed this thing out the door after only 6 years of development & testing :)
Remember the early offroad testing videos and all that rattling racket..? Ford claiming it was supplemental harnesses or something...?
They knew/know all about this but didn't go back to the drawing board over it 🤷

Don’t think that will fix it it. I’m nearly sure it’s a rivet that is flexing or stressing the metal which is causing the tick over any uneven surface. My dealer has removed lubed and tightened every bolt and elements relating to the spare, parking light, rubber bumpers etc. The sound is in the cavity of the gate, closer to the hinges but inside. I suppose it could be related to hinges where they are welded to the inside. aside from driving, you can replicate it on mine when opening and closing the gate, when it’s almost fully opening or closing. tick tick tick.

they couldn’t replicate on another 4 door they had which is good. Meaning it’s not every single one and they are working on a solution.
Any solution? You describe EXACTLY my issue, I can replicate when opening/closing the tailgate like you.

I had a similar rattling sound coming from my 2-door. I put a piece of PPF on the top of the rear door where the back window rubs on the paint. That fixed mine.
