How to fix the window rattle

Garemlin

Oct 22, 2022

One thing I noticed in the first day of ownership is if I had the window down around 4" it would get a nasty rattle when hitting any bumps. I chalked it up to the frameless window and figured I would live with it. Well I came across a thread over on B6G stating there was a service bulletin out for the window rattle. Several people took their Bronco to their dealers and either the problem was not fixed or it got worse. Well I came across a fix that you can do on your own in just a few minutes. I actually added my own steps that made it even easier.

What you need:
-Nut driver
-Long 10mm socket
-Long screwdriver
-A few minutes of your time

-First you want to roll the window all the way down on whichever window is rattling. Might be one. Might be all. For me it was just the drivers side front.
-Open the door and crawl under so you can see the bottom of the door. You will see two rubber plugs.

-Pull one plug off. You will see an adjustment screw.

-Use your 10mm socket to loosen the nut. Don't take it all the way off.
Insert the screwdriver into the area next to the metal clip. It will be on the inside side of the door.

-Apply a little pressure outwards (towards the outside of the door) until the screw is all the way to the outside.
-Hold that position and tighten the nut.
-Reinstall the rubber plug.
-Repeat for the other one.
-Take it out for a test drive and see if your rattle is gone.
-Pat yourself on the back for not having to waste half a day at the dealer with the potential of no fix.

I did this and it worked. Not only did it get rid of the rattle. It also got rid of the high pitch whistling when the window was cracked about an inch.

You're welcome.

I’ll need to give that a try - both my front windows rattle a bit and I was waiting for my next oil change to have the dealer address it via the “official” procedure.

Hope it works for you. I was skeptical but it worked like a charm.

Annnnnnd I bookmarked this for when I get home from work tomorrow.

I brought mine and had the dealer adjust, and it seems worse to me now.

Unfortunately this did NOT fix my window rattle. I think it helped a little but perhaps that’s just my wishful thinking or placebo effect.

You did make sure the screw was all the way to the outside of the door correct??

Indeed I did - I only changes the driver’s side as a test and confirmed that the screw was in the farthest outboard position. Thanks for checking in and I appreciate the assistance. 👍🏼

Well it was fun while it lasted. After a few days both the rattle and whistle have returned. I don't know if it came out of adjustment again. Going to get under and check it out this weekend.

I wonder if this would help my drivers side window from being so floppy when I open the door from the outside. My passenger side is good but the drivers side flops hard and is noisy when opening the door.

It's worth a shot. You have nothing to lose other than a few minutes of your time.

It is also an active SSM if you need to take it in

SSM 50711 - 2021-2022 Bronco - Window Rattle When Driving Over Bumps

Some 2021-2022 Bronco vehicles may exhibit a window rattle when driving over bumps with the windows placed in the partially down position. This may be due to incorrect window glass adjustment from the factory. To correct this condition, perform the Front/Rear Door Window Glass Adjustment procedure located in the Workshop Manual, Section 501-11 > Front doors > Steps 18-26, Rear Doors > Steps 21-25. It is not necessary to remove the door panel to perform this adjustment. During adjustment, set the window regulator nuts to their most outboard position (this will move the top of the window inboard), then reevaluate the noise. Be sure to place the window in the fully down position during adjustment.

my Driver‘s side window rattles a little at the front when I open the door from the outside as well. I wouldn’t call it a ”hard” rattle but definitely a little annoying. I don’t recall it doing it when I first picked it up. Will have to check and see if I have the half way down rattle.
