Poll: Trunk rubber gasket - Who should it look, as designed?

[jebinc]

Moderator note: Fixed a typo in text and thread title "truck" -> "trunk".

Hello all,

I'm trying to determine what the proper, by Tesla design, large perimeter trunk gasket should look like, when installed properly. Specifically, if the outer flange is supposed to be tucked behind the bumper cover or riding outside and on top of the bumper cover. I've attached pictures of mine, as delivered in June 2019. My guess is the flange is supposed to be tucked, for a clean look. The hump I have is due to some other issue with the gasket.

Please post pictures of yours and offer evidence to support your view on this.

I think the proper nomenclature is “Trunk Gasket”. You have “Truck” gasket in BOTH your improperly worded Thread Title as well as your thread text.

P.S. in no way should the word “Truck” be associated with a Tesla!!! Just sayin’. Carry on!

Damn autocorrect... Thanks for pointing that out; unfortunately I can't edit the post. Perhaps a mod can make the fix? So, do you have any input, re the intended request?

I stand corrected! Tesla Pickup and the Semi!!! (I was thinking in relation to the Rolling Coalers!) and hundred and one road rage incidents they’ve attempted on me).

There's a rubber flange on the gasket. By definition that flange should stick out to cover the unfinished edge of the bumper cover.

but if it's tucked in, it's still protecting the "unfinished" edge as you say. if the flange is pulled out, it's creating more wear on the painted surfaces.

Mine is tucked all the way around, like the left half of the photo with the nice labels. July 2018 build.

Confirmed mine is completely tucked too.

So, in favor of gasket flange out:
• why would there be a gasket flange if it wasn't meant to cover the plastic trim of the bumper? Is there any other gasket flange tucked in on the car?
• quite a few people have complained of gaps between gasket and bumper in the corners, would be covered by flange
• the bumper cover edge isn't even a straight line, it's irregular; the flange would hide that

In favor of gasket flange in:
• that's the way Tesla installed it!

Well, I would agree the flange out does cover a lot of sins your car has, as pictured (e.g., gaps, irregular bumper edges, etc.), so that would seem like the best alternative for you. I still would like to know what Tesla engineers envisioned (even if different than how Tesla production workers/robots did the "tucked" installation).

For me, I have no gaps or irregular bumper cover edges, and in fact the "tucked" looks very clean. The "humping" issue down the middle seems to stem from a stiff body part sticking up.

I think the KenC final pick nails it for me, it's supposed to be in! The return flange at the top of the bumper piece and it's slope angle matches the small indenture above what you're calling the cover flange. The bumper fits perfectly into the indent and looks really clean on my 3, IMHO of course!

So, another "tucked" with no humps, gaps, or jagged bumper edges. That seals it for me, thanks! I have since fixed my hump without pulling the flange out. The problem seemed to be a triangular clip "down under" between the bumper skin and sheet metal.

Yeah, I just think it's too coincidental that the pieces fit so exactly.

Can you describe the process to fix the hump? I have an identical hump in my model 3 june 2019 build and I would like to fix it. Thanks.
