Fried hub
Boy I feel stupid. On my way back to Tulsa from my farm in Jackson, MS I started having a severe vibration doing 80 at about Pine Bluff. Felt sort of like a flat but I knew it wasn't. Pulled over to check the tires, lug nuts, and obvious front end problems. About the time I crossed the OK line I thought, oh no, I bet I left the hubs locked at the farm. Yep, that was it. Guess I need to order some new Warn or Mile Marker hubs. What hubs would you recommend and do you think that's all I tore up?

You weren't going 80 mph down the road in 4-wheel drive I hope? 
Locking the hubs and just driving with the hubs locked and in 2-wheel drive shouldn't hurt anything at all. In fact, many people on here recommend doing this in the winter months so you don't have to get out of the cab to go into 4x4 in severe weather.
I'd make sure I went over everything elsewhere before you mess with the hubs.
Does the "flat tire" feeling still happen at slow speeds, or just around 80 mph?
Might be symptoms of an alignment problem/bushing/ball joint problem.

No, I wasn't in 4wd. Yes, it feels even worse at slower speeds. The most comfortable speed is between 60-65. It's still plenty rough, but is voilent over or under that speed. It just started doing it out of nowhere going down the interstate. I would have expected some noticeable visual front end damage if I hit something or was offroad , but I was just cruising along.???

Until you pull that wheel apart, you wont really know. Between the diff and the tire you have 1 or 2 u-joints, bearings between the axle and spindle, and then spindle and hub. All the locking hub does is depress a ring with inner and outer teeth providing a connection between the wheel hub and axle.
If you think its your hub lock, remove the cap and extract the springs and gear, and put the cap back on. If the noise goes away, it was your hub-lock, spindle/axle bearings, or axle u-joint. If it doesn't, likely you have a hub / spindle bearing issue.
