There's a black box of sorts under the rear drivers side of my '04 4dr (4wd, if it matters) Blazer. What's it for and can I rip the bastard out and stomp on it? (It got in the way of the bolts on my new shackles.) It looks like it's got at least one fluid type line and maybe an electrical harness attached to the back of it. Kinda flimsy, too.

 

Charcoal canister for fuel tank vapors. Be nice to it or you'll be bathed in the glow of a check engine light.

 

what the bleep is it doing inside the passenger compartment its got fuel vapors going into it. god forbid gm put it under the body where it cant kill anyone with gas fumes.

 

I misunderstood you.... inside drivers side rear quarter panel is charcoal canister, but it is outside of the truck. By shackles I assumed you meant "spring shackles" underneath the truck.

 

Yeah, that is outside of the truck...

 

Yup. Outside the truck body, under the drivers side rear by the rear bumper. About 2 freakin' inches from the drivers side leaf spring shackle. Thanks for the replies, guys. I guess I'll leave it alone. I was hoping to remove it and try out my new shotgun on it.

 

Nope! Bad idea. LOL

 

well, even knowing what you know now, you STILL can

 

Don't want to damage the truck itself.
