Have a hum in right front that gets louder and increases vibration both by about 50% when turning to the right. Used to disappear when driving straight or turning left. Now still aparant when at all times. With four wheel drive activated, hum changes to a louder noise and vibration increases 200%-300%. Obvious oil/grease stain on lower control arm just inside the wheel. CV boots not torn or visibly damaged. Any thoughts?
You've got a bad axle shaft in the front and possibly a bad bearing in the hub. 4/wheel drive makes the front axle actually work. Theys no real pressure on these shafts when in 2/wheel drive.

You must replace wheel bearings in pairs to avoid loading the old bearing and, in time ruining your new bearing hub it is possible that you have already damaged the new hub
