I have a 2002 silverado 4wd and I am getting a rough scraping or
grinding noise from the front right wheel. Not the brakes. This
happens in 2 and 4wd and is much louder when doing a left turn or lane
change to the left . What is this, a bad wheel bearing? I raised the
truck on a hoist and the axle shafts seems tight, ball joints are
tight, tie rod are tight. Thanks for any help.
