Doors Moving

[Jbraim]

This 2024 2500HD is my 5th since 2016. I feeling when I travel over railroad tracks, multiple bumps in a row, drive down a farm lane, and other occurrences the driver door is moving. I can feel and hear it. This doesn’t seem normal as none of my other truck do it and I have gotten in my buddies 2024 GMC Sierra 2500. Anyone have any suggestions? Striker and Latch look fine.

I would bring it in.  It's not normal, I am on my second 2024 and neither this nor my early build one did what you are describing.

Even though I had the driver's tow mirror replaced, my left ear would still clunking on certain bumps.  I didn't know if it was the door/latch or the shoulder belt reel in the pillar.  I live on a rattly dirt road so when I hit the bumpy spot in the road and heard the clunkity clunk, I cracked the door open and hit the next set of bumps - holy cow, there is a huge bunch of door movement up by the front of the door, like the door mount structure or the hinges aren't able to hold the world's heaviest towing mirror up.  I'll pull it into my shop soon and see if I can diagnose the issue.

The lower door hinge are of the lower A-pillar does flex a little but nothing can be done about that.

The hinge pins are tight although the hinges are much smaller in height than I remember on previous trucks.

The pendulum of the shoulder belt reel doesn't seem to be a cause of the clunk.  Holding the belt tight after pulling it out all the way doesn't affect the clunking.

There is more wear on the frame side of the door latch than normal.  

Maybe it's time to talk to a body shop and see what they do to remedy the issue...

 

Folding the mirrors eliminates most of the clunking so far.  I'll do it for a few days to see if it's a coincidence or the biggest culprit.

That’s not a proper way to diagnose anything. Opening the door while driving down the road is of course going to cause movement in the door structure. You’re losing one whole side of the door’s stability.

With the door closed, can you stick your finger in the jamb/rubber seal and see if you feel movement?

My 2022 is the same way.

You're saying the door latch is a structural element of the door/cab system?  oooooooook.

The door, hinges and the A-pillar are the structural elements in that system and the latch keeps you from falling out of the truck.  At least the door/window don't leak in a big side wind like all my RAMs did.  Your could  physically feel the window frame move away from the cab under the right conditions.  

Anyway, same bumps with the mirrors tucked and seat belt yanked all the way out and still get the same clunking in my left ear.  

Next steps are removing the driver's side door panels and the C pillar cover and hit the same bumps again.

After that will be mirror removal, then off to the dealer and let them look at it under warranty.

Thanks exactly what I’m saying. When the door is closed it is obviously more structurally stable than when the door is open.  Open your door and hang 500 pounds off the edge of it. Hinges will bend. Now close the door and hang the weight off the open window.

Agree.  It's sort of like framing a wall.  With just the studs it is fairly wobbly.  Add the sheathing and all of a sudden it's very solid.

Yeah. I just did my basement last year almost 60 sheets. What a project by myself. Framing, drywall, taping mudding sanding painting, trim etc. 

[Crazy Canuck]

Lol, i have a huge amount if respect for the people out there that can mud and tape well.  I would have to sand forever if I did it myself.

The door latch is a pin joint.  Pin joints are not as structural as you might think.  The door can slide fore and aft and rotate about the pin.  Since the latch fit is not perfect, the door will also move vertically on the pin.  I can see the wear on the latch in the doorframe so there is movement.  The only thing retarding those motions is the door seal, which is obviously not a structural element. 

Roll your window down with the door closed and drive about 20-25mph down a dirt road with some washboard in it.  Watch and feel your door and see how much it moves.  Ever notice how noisy the interior of the truck gets when quartering a stiff sidewind?  Put the ends of your fingers where the window frame meets the cab roof while driving and let us know how it changes.  

If your truck doesn't exhibit any clunks or other issues, good on you.  There are those of us that do experience door clunking and such and are looking for others that may have experience with it and had proper remedies applied.  Claiming my diagnostic techniques are not valid is a matter of opinion and everyone is surely entitled to one.  Since this thread has already devolved into structural OSB and drywall anecdotes, it will probably become inactive in a short time.

Anyway, removing the front door panel does not affect the door clunk much -  more like it is a bit less prevalent due to almost 10lbs of plastic and Styrofoam being removed.  Only have the C pillar cover left to remove and find out what's shaking in there...
