Ok need a little advice it snowed 3 inches here in Tenn today. Had to lock my hubs in on my 2000 f-350 I replaced my hubs last year with a set of warn hubs. Going down the road with the front end locked I get a rumble sound from the left front I can take it out of 4wheel drive and I still get the sound in my left front . My u joints are in good shape everything I've looked at appears good when I unlock my hubs everything is quite.
It has to be the front axle does it not what do you think.

Check the front driveshaft including the double joint...
I'll second that. I have the same issue and have a bad u-joint on the double cardan joint. Will be fixing that as soon as I can get to it.

Take a prybar between the yokes and see if they will move relative to each other. Any movement = a bad u-joint.
