rear glass rattle

[pt1965]

Does anyone have a solution for a rattling back glass? It comes from the 2 hinge pins.

Are the hinge pins worn? Maybe a new seal if your old one has lost tension? Struts ok?
If nothing works, maybe you can try and clock the hinge so there is less play, or pull it closer to the liftgate so there is more seal tension.

How is the rubber molding on the door around the window? If the upper part of the molding is compressed through age, it may not be providing enough pressure to keep the window from rattling when closed.

On this same topic my two back doors sound like they are slammed even when shut normally, almost as if there is metal to metal. So much so that when people get out and shut the door they are often startled and apologize for shutting so hard.

I checked to see if there was any molding or grommets missing but nothing was obvious. I let a mechanic hear it and his guess was it's something with the latch but i'm not convinced. The windows seem to have a little more play than i'm used to as well. Anybody else experienced this and what was it? I got this truck at 206,000 miles so no telling if something was done to(or removed from) the back doors over the years.

I approached a random in a parking lot with the same truck and asked to hear how theirs sounded when shut to see if it was the same. It sounded MUCH quieter and normal like a solid thud instead of a slam. I figure i'll bring it to a body shop or something if i can't figure it out

You do have the rubber bumpers at the top and bottom corners?




My windows are loose when not all the way up or down..

Truck has been squeaky while driving, I think I need to silicone the weatherstripping or back seat latches..

I do have both top and bottom bumpers on the right door but missing the top one on the left. Both doors sound identical so I ruled that out as the problem.

Check the door latch for unusual wear. How are your rear door seals?

 

[pt1965]

the seals seem ok, but hey, they are 13 yrs old. i'm going to try adding some temporary loose door seal around it before i buy a whole new seal kit.

My 23 Yukon just started this at 15k miles. I found this bulletin for 2021.

I need to find if it's still for 2023 models too. It's very annoying.
