What fell off my truck?

I crawl over the curb to park my truck in my side yard gravel. Tonight I pulled out to go to the store and when I came home I felt myself run over something.
Did I lose this? If so, what the hell is it?

Thanks guys, I'm a little pissed right now.

 

Looks like a bump stop maybe. Look on both sides above the rear axel and see if ther is one of those in there.

 

Is that a mini skid plate for the transfer case? Not sure, just throwing darts here.

 

I would have said the same thing if it was a 79-85. Do the 1st gens have them?

 

Could be a bump stop up front as well. I would start by checking the four corners.

 

What does the top look like?

 

Looking at the pictures it looks like it was broke off before and welded back by a third grader.

 

Is it rubber or hard plastic or nylon? the top.

 

Looks like a dampener....something used to absorb or counter vibrations.

 

Still thinking bump stop

 

What about an aftermarket muffler isolation hanger?

 

Maybe its off your lawn mower and fell off the last time you mowed. lol.

 

Doubtful, there's nowhere to hang anything from. In the first pic there's a giant weld gob across it and in one of the following you can see the crack on the backside. If not some sort of bump stop I will say motor mount support of some kind.

 

I was thinking transmission mount, but it looks nothing like mine. Does the 5 speed have a different set up than an auto?

 

I don't think it's "yours", but it is now ! Glad it didn't take out a tire !

 

It feels like a weight, little bastard is heavier than it looks. Daylight tomorrow I'll go look for another one or where it fell off of.

Honestly, I'm hoping it's not mine. But I wouldn't be surprised if it was. Just has me nervous.

 

I still say dampener. The mount doesn't look robust enough for a bumpstop.

 

Probably right. Whatever it is it was broke before and repaired poorly.

 

Is that a nail going through that hole that is then welded to the large round part?
