Rear lift gate glass hinge seperation?!

To all: If you do decide to get the primer (https://www.amazon.com/gp/product/B00473W5V8/ref=ppx_yo_dt_b_asin_title_o09_s01?ie=UTF8&psc=1), just remember. This stuff flows like water. Place this stuff on a foam brush or rag to apply to area that needs it. If not it's going to go all over the place and keep going until it dries.

I used the 5200 on my lift glass hinge a couple of years ago. It just gave away again yesterday, same hinge. I suspect I didn't prepare the surface properly, didn't cure it properly, didn't apply it properly, or something.

Should I use the primer before the 5200?

I didn't remove ALL the old adhesive from the glass so that I could ensure the hinge went in the original spot. Is there a trick to align the hinge if all the old adhesive is removed?

I'll admit I didn't overlap the hinge as much as the original hinge was. This may have been the reason for my failure.

It was cool and I couldn't get the temperature up as high as I'd have liked to get a good cure. The adhesive remained a little soft for weeks. However, it did last a couple of years so eventually it would have cured.

Anyway, I'll be trying this again.

@chevrol8t
How is the repair holding up now that is been a year?

 

[Larryjb]

I heard something about a TSB for the rear glass hinge, or an updated rear glass in following years?

Does anyone know what years and models are compatible with the 2002 glass?

I may get a junkyard glass so I can repair my existing hinge on my own time.

All the glass hinges from 2000-2006 will fit those year suvs. However in 2005 the rear hatch changed. The older style has a trim surrounding the glass and those were the ones that were prone to the hinges separating from the glass. The 2005 and 2006 glass didn’t have the trim surround the glass and just had a small handled bolted through the glass at the base. Not sure how the hinge setup is different they’re not prone to separating like the older ones.
Edit: I just figured out why the hinges are different and why the 2005 style glass hasn’t separated. I’ll post a couple pics.

 

[Larryjb]

So from what you are telling me, a 2005 glass should just slip onto my liftgate even though the hinge is mounted differently. If so, I'll look for one of these. Thanks.

 

[adventurenali92]

The hinges on the older style glass separate because the hinges is formed into the trim surround molding. It’s some sort of soft compound material. This is the 2004 esky hatch I just pulled off my truck:

 

[adventurenali92]

@Larryjb , yes the 2005 style is a direct “plug and play” swap as it were. The top hinges where it mounts to the tailgate itself are identical.
this is the 2006 hatch that was originally on my truck and is still just sitting around my house. I need to get rid of it. Lol. But the hinges are directly on the hatch itself instead of being on the surrounding trim piece:

I'm a little confused at the moment. The picture shows where the lift support attaches, not where the hinge attaches. I'm interested in comparing how the 2002 and 2005 hinge itself is attached to the glass

Oh you mean the top hinges where it mounts to the liftgate itself?!
I was referring to the lift support hinges.

 

[Larryjb]

That's right. It's the top hinge that is giving away.

 

[adventurenali92]

That's right. It's the top hinge that is giving away.

Oh.... that makes a big difference. I’ve never seen the top hinges give way. That’s interesting. But I can see how they would because the 2004 they’re molded into the the trim piece just like the lift support hinges are:


And the 2006 top hinges:

View attachment 258126 The "trim" is actually a structural urethane adhesive. Unfortunately, after a number of years of service, it can break away.

So, how is the hinge actually attached? Is that glass that it is attached to? Is the glass attached to a metal frame? What is that hole to the left of the hinge I see?

I have seen online many examples of this hinge giving away. Unless I can find a 2006 glass soon, I'll do another urethane repair.

I have no idea how the hinge is attached on the 2006 setup. There’s no metal frame that I can see. I’d guess it’s got adhesive right to the glass structure. All I know is that I was on my truck until a couple years ago when I swapped for an Escalade hatch and it never gave me any separation problems while it was mounted. Not like the other hatch. Anyways, the hole to the left you see is where the large black plastic trim that comes on every 2005 and 2006 tahoe, suburban, Yukon, and Yukon xl mounts. That’s where the screws go through the glass that mount that plastic piece. There’s three holes across the hatch just like the Escalade.

All the pictures from scrap yards of the 2006 seem to show the same glass used from 2002. I haven't found any 2006 to see yet.

So, I'm hearing that 2006 Tahoe/Yukon will fit. What about Suburban and Yukon XL? Can anyone confirm compatibility?

(I would expect so, but I've also learned to not expect in these matters.)

Nope glass changed in 2005. I see them driving around all the time and see the different style. So the junkyard you’re looking through doesn’t know the difference. Lol. And yes the glass hatches are interchangeable between tahoe, Yukon, suburban, and Yukon XL. They’re all the same mounting setup on the liftgate.

 

[Larryjb]

I may have found one. Depends on if they still have the truck. It looks like it's been in their system a year. I bet they don't keep their system updated so I'll have to phone.

My passenger side hinge is still separated on my 2001. That glass has that hard rubber surround and the hinge is molded into it.

So you're saying glass from an '05-'06 is a direct swap onto the '01 and the hinges are mounted to the glass and not the rubber surround?

 

[Larryjb]

I saw at a junkyard an 02 Escalade with the 05/06 glass. Must be true. The pictures look deceiving, but the 02-04 has a rubber flap glued to the top of the glass, the 05/06 has that plastic molding mounted to the glass. I'll see soon enough I suppose, when I find one.

For the third time!! Yes!! The glass from the 2005 and 2006 SUVs will fit directly onto an older SUV! Lol even though on the older glass the top hinges are integrated in to the trim they are still shaped exactly identical to the newer ones and the newer ones will match up the tailgate hinges on the older trucks. Lol
