Sliding Glass Latch Rubber Isolator

[TeKdo]

Does anyone know the thickness of the rubber isolators that are supposed to go behind the split window latch are? Or at least it's what I think feels like a rubber isolator.

 

Ever since the weather's been in the 30s and 40s here my rear glass has been rattling at the latch and I can see/feel what is supposed to be a rubber isolator on the back of the latch that has just shrunk over time. I'm guestimating it to be between 1 or 2mm but wanted to double check to see if anyone has an exact measurement so I can order a rubber sheet to make a new isolator.

 

I've got a piece of cardboard wedge in right now just to stop the rattle.

I didn't realize there was supposed to be a piece of rubber there, mine rattles too.

There is no rubber there, the latch is attached directly to the glass just like the rearview mirror button.

If that's the case, then I'm gonna add silicon or putty or something to the back of this thing. The screws are tightened as far as they'll go and I can't stand the rattle on this thing right next to my head. My Comanche is my daily for the winter and I definitely can't live with the rattle every day for a couple hours.

What screws?

Mine has little Phillips head screws holding the latch to the glass. There's 2 screws per side and. They go to a backing plate on the outside of the window. I'll take a picture tomorrow if it's confusing too.

Been a busy morning but here's a pic of the setup on my glass...I'm assuming that since you're asking about the screws that they're not factory

 

The other side is fastened to the window the same way too

Yes, not a stock slider, is that a four panel? The stock clip looks like this with two fixed glass panels and a single slider.

I can get pictures of my 4 piece slider stuff in about a week in a half. I can’t recall any rubber there, but mine will rattle unless I have both windows square in the frame.

Yeah no, mine is 4 pieces. It's got a 2 piece center window that slider half to each side of the cab. It's the same from some old GM square bodies from what I've seen. I do know that all the glass except for the windshield in this truck is original and it's never been out.

That's probably my problem, the rubber seals on the sliders are perished and brittle. Can I replace those with the glass in the truck or I do have to disassemble everything to fix this?

That slider is not original, it’s probably a C.R. Laurence replacement.

That would probably explain why the rear glass is tinted too then

Could you get a Laurence slider to fit into the factory glass back in the day? I read that the Laurence ones have a metal frame but mine still has the big stock gasket

I’d bet that it needs to come apart. You should be able to get it positioned right so that it won’t rattle.

They have a metal frame and can use the stock gasket.

I can see that now. I also just noticed that the latch even cays CRL on it.

[fiatslug87]

Maybe CRL stands for Comanche Rear Latch

my CRL rattled when new over 20 years ago.

I guess that's mystery solved then, I'm gonna look into adding a vibration damper of some kind behind the latch. Confirmed my rattle is coming from the latch specifically since the window is square in the frame and goes away when I just touch the latch. I'll see how roadkill I can get with this solution soon
