    Hello all,
    New to the forum. I just replaced the drivers side bearing hub assembly on my 2003 Chevy Silverado. I have a humming noise when driving that stops while turning left, taking the weight off the drivers side tire. So I assumed the bearings. however, after replacing the bearings I still have the humming noise. What else could be wrong?? I did notice a clicking noise from the differential when replacing the bearings. When I turned the wheel the differential would "click"?

    maybe it wasnt a bearing, do you have 2 or 4 wheel drive?

    My apologies, meant to tell everyone I have a 4-wheel drive. I'm guessing there is something wrong with the front differential?

    Sounds like it is coming from the constant velocity joints.

    Most of the time it is the bearings and it is CRITICAL to torque the axle nut properly or the new besring will quickly die. Also the chinese bearings on ebay or anywhere below like $100 will not last. I use timken and have not had an issue.
