Firewall grommet replacement

Anybody got a replacement part # for that main grommet on the drivers side? Mines split pretty bad, anybody tried to replace there’s? Or do I just throw the silicone to it and call it a day?

 

I'm pretty sure the boot/grommet you're talking about is part of a larger assembly and not necessarily sold separately. The larger p/n is 82111-0C3xx where xx can vary between '06 models as 20, 40, 60, 11, 31, and 51 (to name a few).

If Toyota did sell it independently, you should be able to find a part number embossed on your existing rubber seal, somewhere, likely on an edge or something. And/or you may be able to find the manuf'er.

 

@shifty` dang for that money I’ll throw the silicone to it inside and out and call it good. I did see a guy on some 4Runners boards get lucky and find one in a junkyard

I cut mine in my 4runner when running new amp and subwoofer cables. I put a bead of roofing / flashing caulk to fill the hole that was cut and never had an issue. I wouldn’t even attempt to replace the grommet if it were me - that thing is a pain in the ass

 

That's the downside too. To replace, unless you slice it in half, which makes it lose integrity, you're basically unplugging everything either on the cab side or engine bay side (cab probably easier), fishing it back through the firewall, sliding off the boot/grommet, sliding on the new boot/grommet, then reinstalling everything. It's a pretty significant job.

 

I siliconed the ever lovin hell out it. It ain’t pretty but it should effective

 

I remember when I was cash-strapped and buying packs of Culprit worms really ate into my beer $$. There were these 'worm welder' tools that were almost like a soldering iron, and you could use them to - within reason, assuming whatever lunker you pulled in didn't destroy it - "mend" your worms. It worked pretty well to cleanup gashes from when you'd go to set your hook and miss, stupid crap like that.

I can't help but wonder if there isn't a similar tool for rubber grommets and the like. Surely there must be a way to meld that rubber back together?

 

@Shifty’ - remember back in the I had this vulcanizing kit that had a clamp and a bunch of small metal trays with a rubber patch for inner tubes. You clamped the tray with the patch over the hole in the tube and light the material in the tray with a match. When the fire went out you removed the clamp and tray and the patch was vulcanized to the tube. Maybe someone could develop something similar for grommets.

 

To your point, I wonder if this is being overthought. Maybe simple bike tire patches with vulcanizing glue would work? OR whatever the glue is I use to patch innertubes...
