I have a 2012 F250 and it has been clunking at low speeds, below 10 mph. I have read all the posts on here about clunking and they don't sound quite like mine so here it goes. Mine is making a good thud/clunk when I am at low speeds mainly when making turns. It doesn't seem to happen when I go over speed bumps or pot holes. It started happening only when backing up and making turns at the same time. Now it is happening when going forward too. For example if I back into a parking spot and then pull forward out of it. It will most likely clunk twice. It isn't a metal on metal sound, it's a thud. You can also clearly feel it in your feet. I have looked under it and don't see anything that catches my eye. Anybody have an experience similar to this?

It would be a good idea to have someone look at all the tie rod ends and ball joints as you move the wheel back and forth. How many miles? I just replaced ball joints and tie rod ends in my F450. But it has 195,000 VERY ABUSED miles. I took my truck to a small tire shop for an alignment, and they checked it first, so as not to waste their time trying to align it. They checked it for me for mo charge. It took all of five minutes.

I agree with taking it to a tire shop to have it all checked over. If they find nothing then grease the splines on the slip yoke.
Maybe ball joints, but this usually maninfests over bumps.
Maybe need to regrease the slip yoke in the drive shaft where it goes into the transmission. Motorcraft has a teflon grease for this, it was an issue on some 150s.
Could be a u joint, I've had bad u joints do that. When they get really bad they sound like raccoons fighting over a box of lucky charms while your driving.
Could be a cab mount or a swaybar link. I saw a tsb about a bad cab mount needing a spacer or something. Have someone rock the cab back and forth as hard as possible, (2 big guys bouncing on the running boards see saw style) while you listen to the cab mounts. Under the driver floor part in particular. 2xl big should be good enough, 5-6xl might snap em off...
Hopefully not something in the rear gears.
