Cluncking noise
I have a 2008 F250 4x4 6.4. Just bought the truck 2 weeks ago. Now I hear a cluncking noise when hit a bump with passenger front tire. I thought GREAT ball joint is bad. So sent it to the very good shop in town to verify it. 2 mechanics test drove it and heard it. They checked the whole front end and said everything was tight and couldnt find where the sound was coming from. These guys are usually really good with gas vehicles, but they dont do alot of diesel work but that shouldnt matter. Anyone with any ideas, i have an appt at a diesel shop (for a different matter, a check engine coolant code just came on too) was gonna have them look at it. Im trying to save a little cash, im sure the ect or thermostats are gonna cost me enough. lol Any help is appreciated.

So, 2 mechanics drove the truck, heard the noise but can’t identify the cause? My recommendation is to find a new mechanic.

Three people have heard the noise. A clunk is usually created by a loose or broken part. Prying and pulling on stuff from underneath is where I'd be looking. Also, check simple things like the battery tie-down system. Perhaps it/they are loose and the battery is dancing while moving. Also front end equipment like radiator, coolers, grill etc. You know it's there ... now you just have to find it. What about the slip joint?
1terribleshot, Redford has an excellent point. Say you went to the doctor and you had on-going symptoms of a sharp pain on your right side. Would you be satisfied if the doctor said "I see you're in pain but I have no clue what is causing it". Wouldn't you look for another doctor who would keep going until they correctly diagnosed what was ailing you?

Got a funny story to tell quickly then will get to my point. Got up early in the morning, just me and my son awake. Went outside and fired up the truck (2015 F350 V8, 6.7L 4WD DRW) then went inside to get some coffee for the 50-mile trip I needed to make. My son went outside and came back in telling me my truck was making an unholy noise. Almost passed out thinking serious engine probs. Ran outside and sounded like my truck had changed into the loudest of tractors. Granted diesels sound like tractors to begin with but this was seriously pronounced. Turns out the moulding surrounding the cavity the small fog light sits in on the driver's side had warped just enough to vibrate against the outer bumper moulding. The resulting sound combined with the engine noise was awful. Needless to say I had no idea where to start so went with the KISS principle first before digging around into the more detailed stuff. Found it in like 5-min. Point being start with the simple stuff some of the folks suggested above first. Could be something very easy to correct. Will keep fingers crossed for you.

Get a 3' pry bar, truck in park, emergency brake on, safety glasses, update will, and start prying on engine mount, body mount, and everything else that moves. Rubber mallet on everything else. Good luck.
