Nissan Repair: Humming, nissan hardbody, brake drum

Question
Hi Von I have a humming noise at the rear of my Nissan Hardbody 1999 4x4. This noise comes and goes depending on speed. Could it be the bearings??

Answer
Michael,

Yes, if you have a whining noise coming from the rear it could be bearings or if there is vibration associated check the universal joint in the back as well.  Jack up the rear and put the truck in neutral and spin the tires with your hand and see if there is binding.  Sometimes a warped brake drum can make the noise too.
