Front axel (4wd) "clunk"

So I just finished (a few days ago) cleaning up the turbo AGAIN!, and installing a BPD egr cooler and a new oil cooler. What does my truck reward me with??? Well the front left wheel/hub has (4 times now) caught and popped with a good clunk like something is catching in the wheel locker. All four times it occurred was when I was coasting with light braking up to a stop (under 10mph). Something is going to break! I can hear it making a sound like a one way gear buzzing just before it happens with my head out the window.
Any ideas?

U joint possibly. I just had to replace mine because it would bind in one position.

It's more like the hub trying to engage 4wd. You can hear the gears rubbing on each other then catches with a somewhat violent bang.

BTW, I did put the grease gun to the U joints. They havn't been greased in a couple of years. Thanks for the reminder.

Glad I could help with something. Do you have the esof system, or just the manual lockouts?

ESOF ('06 F-250). I'm wondering if the esof is pressurising and trying to engage the hub. Is that possible?

No clue from this end. I would think it could be a problem, but wouldn't you hear the vacuum pump going? I bought manual everything for this reason. Lol.
