    Hi Guy's

    2006 Chevy Silverado lt extended cab 4.8 I bought new. I have a loud humming noise from front end and I just put brand new tires on yesterday and replaced both front wheel bearings and this noise will not go away. I have jacked up rear end with the wheels off ground and pushed it and found no noise like from universal joints etc. and now I am at a total loss on what to look for now. This noise gets more pronounced the faster I go.:neutral: I am also new to the site and belong to motorcycle sites also for my bikes which help is great and hopefully this site will help as I am sure it will

    Sounds like the Front differential needs to be checked out.

    When was the last time the front differential was serviced/checked? I know this sounds funny but ALOT of people forget to service/check the front differentail. I change my front diff. fluid every year because it does get used several times a week.
