Rear lift gate glass hinge seperation?!

[chevrol8t]

Okay I popped my rear glass on my '00 Tahoe and I heard a "tearing" sound now my rear lift gate glass will no longer close. I soon discovered that the upper portion of the hinge that is connected to the glass is held together by some sort of adhesive? Please tell me that GM or someone make an adhesive like this. I really don't want to buy a replacement glass just because of "glue separation".

However I have a funny feeling my answers will not be what I want to hear...

Thanks in advance...

the glue on my 2012 glass did that, tried looking around to see if there was a fix or something "industrial" that would work but no luck, the glue remained "glued" to the other part of the hinge and was probably not going to come off without a fight, I asked the dealer and they said they did not know of anything either so I ended up just buying another glass

glue separation is common with GM


your not the first and not the last you have to get the glue and take off the old stuff and put new glue and hope it aligns correct

The right side hinge is "unglued" on our '01. It's been like that for about 5 years. I removed the lift support on that side, otherwise the glass was lifted at the top and had a gap. I can still open the glass, but I have to hold it, it will not stay up by itself with that lift support removed.

I thought about removing the glass and using something like JB weld over where the adhesive is cracked along the top of the hinge, or also trying to remove the existing adhesive with a wire wheel or something and using JB weld or another adhesive, but just never got around to it

I might try that. I would like to find the best adhesive I can get my hands on Vs paying 3-$500.00 for a replacement.

I would like to keep the functionality of the rear gate.

I just remembered about 6 years ago the fixed back glass on my Astro AWD busted out. Got an ebay replacement and used this 3M auto glass windshield adhesive for the install. Damn glass never budged again.

I came home to my Yukon rear glass shot up in the air like a spoiler last year. Easiest thing to do is go to the junkyard and get a whole new glass with good hinges.

I had same issue with my 2001. I used a 2 part epoxy and it’s been holding now for 2 months.

I had a hinge pop a little over a year ago. I bought a replacement glass and it failed withing a week. I had a replacement sent and it failed too. Both were GM parts. I cleaned off the old glue and used rubbing alcohol to clean the area. I then used this epoxy to glue the hinges back on: https://www.amazon.com/gp/product/B005K091ZU/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 . It's been holding for a few months.

Sorry for the late reply. Just want to thank everyone for their input. What I decided to do was purchase 3M one step primer and 3M Glass urethane Window adhesive. Been holding well and tough as a rock. no alignment issue when closing the hatch either. Hopefully it will stay that way.

I saved your link to my amazon favs just in case this fix gives me trouble!

Did you remove all the old adhesive or just apply it to/in the crack?

That is where it got interesting. I heard to not remove all of the old adhesive and to use it as a "base" and to just scuff the existing to promote adhesion, apply the primer then adhesive. Then there were others who removed everything, starting from scratch. I chose the former. To make things clear. Right after my initial post here, the following day both sides finally gave ripping at the same time. So with both already detached I scuffed, primer and applied a healthy dose of adhesive and mounted back to the window. I gave 48 hrs to cure and I'm telling you it's sturdy. I guess only time will tell if this path was the correct one or not.

I used JB weld on my one hinge. It busted again. Its very hard to keep it lined up to dry. I may get a junkyard one and use glue in future if it breaks away too.

So far the 3M adhesive is holding steady, even in the AZ heat. I still monitor it (hinges) however, checking for possible separation. If you do decide to go my route don't forget the adhesive primer. Is it necessary? Maybe not but I used it anyway before using the adhesive.
