and a big rubber gromet fell out and I don't know where it goes.
The truck is a 2003 tacoma extra-cab 4x4 TRD 5 speed.

Thanks,

That's pretty vague... you got any more descriptors? Maybe even a pic?

 

OOPs realized I didn't put in when I droped the front skidplate -sorry
its about a 1" dia rubber gromet - fell out when I drop the skip plate.

 

Any way you can get any pictures?

There are some pretty tech savvy folks here. Maybe they'll know just by the description

 

My theory is that if it isn't a peice of broken/sheared off metal, it's probably nothing.

 

Sounds like something that was previously dropped on top of the skid. When you removed it, it fell out.

 

here are a couple of pic-

 

this is pic2

 

whats the diameter? that just looks like a firewall plug/grommet. check around the back of the engine wall for any holes that go into the cab. may have fallen out, though i dont know why it would be caught up in your skid plate

 

I'd be interested to know what would need a grommet like that but not have something going through it.

 

This might help.

My 2003 4Runner has a couple of holes in the front skid plate that is plugged with these rubber plugs. I already lost a few in action, so dont worry too much. Check you skidplate(s) for holes that is the same in diameter. There are a couple towrds the sides and front of the front skid plate that might fit, check both sides of the skid plate you might see one hole plugged and one open.

 

i have a grommet like that in my firewall on the drivers side for my 4runner, nothing was going through it at all, just a hole with a plug. thats where i now run wires through from switches for my lights. its located down and to the left(toward passenger side) of my brake booster. most vehicles have them

 

Might just be me but kind of looks like a grommet for a pcv valve.

 

There are several of those in the cab area. Get underneath the truck and look up at the floor area carefully with a flashlight. One of the O2 sensors passes thru the floor on the passenger side to a connector under the seat. It uses a plug similar (...but NOT the same, has a wire going thru it...)as the pictured.

It is pouring rain here or I would go under mine and look around. Better stay out of deep water until you find where this came from. Life could get interesting otherwise.

 

This will sound really nit picky, but that grommet - wherever it came from - is covered under warranty. Just a thought.
