i got a 05 f250. just got home and saw a baseball size puddle leak under my truck. when i went to investigate it, i saw these two bolts on the ground. any idea what they are. How/why they came lose. i imagine they came off somehow.

 

do you see where the leak is? What kind of fluid?

 

I can't tell - do they have a shoulder on the threads? What size is the head? Look kinda small for a pulley bracket.

 

ya the leak seems to be from my oil drain plug
as for the bolts i can measure them and everything tomorrow.

 

Those look like flexplate bolts...are they 16mm? If so looks like one got partly mulched

 

i will measure them and see what size when i get home. my opinion i think they're to small to be 16mm. then again they could be. both was in different spots under my truck. i should also say.

 

welp they seem to be 16mm so i was wrong.. i got no idea how they came out. the truck runs and drives.
any ideas how it came out the flywheel and what i should do to fix?
i posted better pictures of the bolts
i did just replace my front calipers any way they could of came from that? i dont get how they came from my flywheel

 

 

Was the truck recently worked on and/or the trans removed?

 

Well, I haven't taken enough apart on these trucks to know what these are from but it seems odd that they would come from the flywheel. But, of course, ANYTHING is possible it seems like when it comes to vehicles.

I tried to do a search for 2005 F-250 6.0 brake caliper bolt and this is what came up for me. Even though it's from Parts Geek, there are other options if you scroll down. These look similar to those but yours may be a bit shorter. So, I'm not sure. Since you said you just worked on the calipers, I would consider that a possibility. However, YOU are the only one that would know if you tightened the bolts enough AND they weren't cross threaded so they came out on their own. I "hope" you're not the kind that doesn't at least start a bolt and give it a few turns BEFORE using an air ratchet or electric ratchet or other power tool and just letting the power tool do the tightening. That's just asking for problems if you're not at least starting the bolt and doing more than a turn.

I'm leaving more towards flywheel bolts since as someone else pointed out, they "look partly mulched". If they fell out of the flywheel, it would be likely that they would "grind" against a few other metal parts in the bellhousing before making their way out. I'm actually surprised that only one of them is "mulched".

Now, if they were caliper bolts, even if they made their way out, what are they going to hit on their way to the ground that would "mulch" them? I suppose if they somehow lodged themselves in between the inside of the rim and the rotor or caliper or something else, then they could have gotten "chewed" up. But, they almost appear to be too short for caliper bolts. I'm sure you know the unfortunate situation here which is to spend some time peeking through the bellhousing and rotating the engine while you observe each bolt hole and see what happened. I know that's probably not what you wanted to hear but you can obviously get underneath and spend a whole 5 seconds figuring out if these are the caliper bolts. And since you know that's all the time it takes and you haven't came back to tell us that the caliper bolts are still in the calipers, my guess is you either haven't done that yet or, you have and you just don't want to do the other task of looking inside the bellhousing and rotating the engine.

Have fun.

i replaced all hardware when i did the front calipers.
i did both sides. i had my buddy help me since its the first time i have done calipers. i just figured i could of left them outside by the truck. both bolts was not near each under my truck.
the chewed up bolt i figured i ran over which is possible.
it isnt like i dont want to figure out by looking. i honestly have no idea how to. im in no. way shape a mechanic. i know how to do basic stuff. and can do other stuff while watching a youtube video

 

A 10.9 is a relatively expensive high strength bolt. OEM's just don't put those on everything because of the cost. Whatever they're suppose to be holding on is important if it used those 10.9 bolts.

Caliper bolt sounds right. The short threads mean it's passing through more than sheet metal. The shoulder prolly has a purpose too - that made me think of the pulleys.

 

im going to try to figure out how to check my flywheel. just to see. i have only owned the truck a year.

 

Your girlfriend and/or ex-wife didn't sabotage your truck, I hope???.....just kidding (?).....
