Bad idler pulley (belt), bad alternator bearings, water pump..pretty much anything driven by the belt would be primary suspect. If all that checks out bad engine bearings are also a possibility. As well.
check the u- joints for looseness. The humming noise may be harmonic vibration from u- joints, un balanced drive shaft, or incorrect operating diff angles.. Check what tires you are running as certain tread patterns will produce a hum on certain hard surfaces.
most likely if its a hum it could be tires , if its a roar it could be the drive train
support the vehicle on jack stands , start the engine , put in drive and let it idle, if noise is gone ...its the tires if not check the drive train ...start with fluid levels
how does the trans fluid look?at proper level?it sounds like the front pump in trans is starving for fluid..filter may be plugged..does it shift ok?any fault codes?i would check these things and probably drop trans pan to see if any debris/dirt/metal in pan indicating an internal problem..i hope this helps
