Hum/vibe/grind under feet!

Took a left turn at intersection,(slow turn on a slight decline; 5mph slow) wheels felt like they were loose, jiggling feeling and sound under my feet, slight play on steering wheel. Parked and looked around under front tires, nothing. Thought it was just a bad spot in the road. Continued driving, stopped here n there (running errands) with no other problems. On the way home, going about 55mph I feel it again, this time followed by a loud, high pitched screech/grind on driver side front! The hum/low vibration was back under my feet. Drove home slow (45mph) another 15 minutes, parked and went under the truck. Couldn't see or hear or smell anything different. Nothing leaking. Steering was fine. HELP!

 

maybe the front wheel bearing is gone. Lift the Left Front wheel off of the ground with a floor jack. Wiggle the wheel with it off the ground to check for looseness/play. Also, spin it to listen for any abnormal noise like grinding..

 

Thank you I'll give that a go.
