This has been going on intermittently for a year now, but is finally getting constant enough that I am confident that it will do it when my mechanic is driving it...
On my 2004 Silverado (120,000 miles, 5.3, 4x2), I am getting a rhythmic knock (from the inside of the cab) or a click (from the outside) from the front end. Happens most reliably at around 5 mph, upwards towards 10 mph. It goes away if I touch the brake pedal. It will continue to knock/tap when I turn the steering wheel. Best guess is that it is coming from the driver's side corner. I am not getting any moaning at highway speed, just the knock/click.
Last time I had the front end up in the air, I pulled and tugged on each front tire (at 12 and 6 position... and 3 and 9), and didn't get any play that I didn't expect.
I had a front driver's side wheel bearing/hub fail on the 2000 Sierra (150,000 miles, 5.3, 4x2), but it was making a moaning noise at highway speed and had the expected play/clunk at 12 and 6 when tugging on the wheel. It had the symptoms that I expected from a failing bearing.
It isn't anything in the tread of the tire, but that's what it sounds like.
