My truck has had a vibration in the steering for the last year or so, only when turning slightly to the left. Last year I took it in to the dealer for this and they replaced the right side wheel bearing (under warranty), the problem didn't go away. I thought it may be the tires causing it.

Over the winter I didn't notice it much. Now this spring it's started to do it again, plus there is a scraping/grinding noise at low speed (less then 40km/hr) at a rate of one tire revolution, and its not the brakes.

I found a post over on fullsizechevy, that described the same scraping/grinding noise, and it turned out to be the axle bearings in the front diff. I just checked my axles for play, and the drivers side has at least 0.100" of movement, and the right side has hardly any movement.

Has anybody else had this problem?

Just a wild guess here, and I mean wild, but could/would it maybe be the universal joints. Maybe there is some sort of free play in them causing noise.

Well I found the problem, its the left wheel bearing. I had the truck jacked up and when I spin the left wheel it makes the rumble, rumble noise. So I took the brakes off and pulled the cv shaft out to pinpoint the noise down to the wheel hub. I tried pulling the abs sensor out to check the condition of the grease, but the sensor broke off inside the hub, so now I need a wheel sensor and a hub.

I was hoping it was the axle bearings, they may be harder to change but I'm sure there cheaper then a $300 wheel hub .
