Something fell off, what is it?

[explr1]

I hit a speed bump at 40 and heard a big groan sound and something metal hit the ground. I got out and found this in the road. What is it? Thanks........

 

[explr1]

Heres the other side.

 

[ahhjaws]

How big is it?

 

[JoshC]

Looks like it's about 2-3" OD. I don't have a clue what that would be.

Wow that's wierd. The sqaure hole is confusing. I would look under your truck for another one like it. How big is it?

 

[AlaskanJack]

Well if you don't figure it out just wait for something else to fall off and it was probably holding it on.

Are you sure it fell of your truck? Maybe you drove over it while driving. I work for the Highway Dept. And it kinda looks like a key top for either a water valve or a gas valve.

 

[X~FACTOR]

Did you look underneath the truck? Is there anything hanging down, loose, or something? It looks like some type of a washer that is on top of something round- like a ball joint or bushings...

 

[explr1]

It's 2.5" wide, nothing visually hanging down, or broken. Thats the thing, I don't know what it is. Maybe I kicked it up and it hit the wheel well and that was the noise. I just wanted to be sure. Thanks.....

That's what I'm thinking you might have kicked it up from the ground or something. I'm really curious to know what it is. I told you what it looks like to me. But you never know.

 

[MrShorty]

Could it be one of the harmonic balancer things that they attach to the differential or t-case or engine? Those usually have round holes though don't they?

 

[Robb]

Does it tick by chance? Cause if it does, it is probably a good thing that it fell off!

 

[jimbo74]

it looks too beat up to have come off your truck.... i am betting your suspension bottomed out or it flew up and hit your floorpan and made a thunking sound.......

 

[AspenX]

Oh man dont you guys know anything, its a fossilized doughnut.

 

[AspenX]

Could it have anything to do with the radius arm bushing?

 

[JMT1SOMR]

Is it ceramic and where there any fire hydrants near by? It looks like it came off the top of a fire hydrant (there's on in my front yard) -- I'll snap a pic of what I'm talking about tommorow. My guess it that you drove over it.

Not on a 97 (they dont have radius arms).

I think it came off some other car, but check all of the body mounts to make sure it isnt a big washer that came off after you lost a nut. It looks like a washer that goes next to the rubber mounts on a shock absorber except its too big. Maybe it came from a Peterbilt.

man I thought long and hard about this, and I think I MAY have an answer for you. Check your tensioner. I can't imagine this part would have come off, and I'm not even sure this is true on a 97, but on my 00 F-150, the tensioner uses a 1/2" square hole to loosen and tighten.
Dangit I just went back and read through the posts and it said thats about 2-3", which would make the hole bigger then 1/2"... hmm ok I'm stumped.

 

[Heath]

Is the square hole 2.5" wide or the whole piece 2.5" wide???

It can't be anything vital to the engine or the engine wouldn't run. Honestly, it doesn't look like anything that would be on a truck. Just by looking at the surface of the object, it looks like it has been sitting outside for a while because of the buildup that's developing on it.

You probably hit the bump, heard a clunking noise from the suspension or elsewhere, and thought something came loose. Then you went back and looked and found that random object.
