humming noise driver side front end
2015 dodge ram 1500 pick-up the truck has started to make a humming noise in the front end like a whining noise because when you go faster the noise gets louder and when you slow down the whine gets lower. I jacked up driver side to spin wheel didn't seem to be from there

Still under warranty? Take it in. 
If not, find a nice straight stretch of clear road. One that has little or no traffic. Get the truck moving enough that you can clearly hear the noise. Start changing lanes, abruptly. If the noise changes when you do, you have a wheel bearing going out. It will be on the side on the OUTSIDE of your turn, when the noise gets louder.

Sudden change or gradual change in appearance of this new sound?
If there is no obvious vibrations .... then humming or whining or whirring noises that increase or decrease in pitch and intensity with speed are:
- Tires
have you recently changed the tires? more aggressive AT type tires are louder.
how is the alignment, any recent hits that may have put it out of alignment? tires may be scrubbing.
are the tires getting old and worn down? May be getting into the harder under layers of the lugs rubber which are always noisier
Is the sound there in 2wd? How about in 4wd? 4wd operation is always louder as there is internal binding in the gearing and differences between the front and rear tires. Always!
- Bearings
Front wheel bearing hub. Does the sound get louder in turns at speed? Louder in a left turn, passenger hub bearing. Louder in a right turn, driver hub bearing.
Transfer case bearing wear. Is the sound in 2wd? Rear output shaft bearing. Is same in 4wd? Rear output shaft bearing. Is only in 4wd? Front output shaft bearing
- Fluid levels
Low fluid levels in differentials or transfer case; the truck will let you know soon and quickly that it doesn't like it. Especially humming and whining about it. Check them.
Hope that helps to give you some ideas of where to start looking and testing!
