I'm getting a metal on metal scraping/whirring noise, that directly correlates with speed, and doesnt seem to have any relation to the brakes. It seems to be coming from the passenger side front, but I havent had a chance to pinpoint it yet. I have the HP dana 30 with ABS, so it looks like I'll need to replace the whole hub assembly if it is a bad wheel bearing correct? I'm really leaning towards wheel bearing because even prior to swapping in my non ABS rear axle, my ABS light was on. I have read that a bad wheel bearing will throw an ABS light. The only other thing I could think of is a rock or something stuck between pad and rotor because I can see a pretty good groove in the rotor through the wheel. If it werent so damn cold I would have the wheel off, but maybe i'll take a peek tomorrow. Any imput guys?
