I picked up a 99 Dakota Club Cab Sport 4X4 (5.2, auto) a few months ago as a tow and trail truck. Recently I've noticed an occasional noise from what seems to be the left front wheel area when turning or backing up at slow speed. The noise might best be described as a high-frequency, low-pitch grinding sound that can be felt slightly through the brake pedal and floorboard. When the noise occurs, it will stop if I apply the brakes. I recently replaced the front pads and had the rotors turned; rechecking the work didn't show anything obviously wrong. I understand that there's a TSB for early (97-99) 4WD Dakota's front hubs, but the posts I've seen on it seem to involve higher drving speeds and a clicking or popping noise from the front end when stopping. I don't think the noise was there before the brake job, but I can't swear to it. I didn't think it was pad noise, since there's a vibration that can be felt. Any thought on the matter? Thanks for any help!
