Awful sounds from rear bronco hardtop. Any ideas?

[bobzules]

Looking for help from the community and ford. Please see the attached video, sounds are awfully loud and occur especially at low speeds 0-40, worse on bumps.

Things I Tested:
1. I took the tire off thinking it was the tailgate as the issue and the big tire hardtop was still on and noise still there.
2. Rear hardtop off, tire off, noise gone.
3. Rear hardtop off, tire on, noise gone.

Confirmed source of problem but can't seem to narrow it down. Maybe @Ford Motor Company can fix this or has a resolution. Any help, thanks.

hard to tell but it might be the tailgate rubbing the rear glass seal. That's what made a similar noise on mine. Put some silicone grease on there, that quieted mine right up.

Don't use WD40 or any other petroleum based product as they have a tendency to degrade rubber over time.

Might try some graphite lubricant between where the top meets the body panel. It might give a little "slip" to stop the squeak and not attract dirt/dust like silicone or lithium lube.

Hi there! Will you send us a message with your VIN and your local Ford dealer? I can look into things on my end.

Sounds very much like the rear window rubber needs silicone grease as stated above. Mine does htat when I clean the seal too aggressively. This stuff works great. https://www.amazon.com/gp/product/B00MWLDALQ/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
