On my way into work today I noticed a faint banging/thumping sound in rhythm to the tires as I turn right. It is more distinct the slower I go and less distinct if I apply the brakes. Turned the VDC off and it still happens. Sounds like it is coming from the right rear. Braking, handling, steering feels normal. I inspected the truck and can't see anything unusual, nor do I smell any unusual odors. Might take the wheel off when I get home tonight and have a more detailed look. I have a service appointment on Friday to have it checked out. Any ideas?
