I occasionally hear a very distinct "CLUNK!" in the front end of my truck.
Sounds mechanical, like a bad ball-joint or something.
It happens most frequently when taking off from a stop where I have to turn.

I've gone underneath to ensure everything is good and snug, as well as lubed.
Nothing "jumps-out" as suspect.

For the weird part.... I usually does it when it's wet.... either during or after rain.

Ideas?

The vehicle is a 2003 F-250 4X4 PSD Supercrew, short wheel base.

Thanks in advance.
