Our well maintained 99 V70XC (98k) had a barely audible squeak (only in forward motion) that sounded like there was something (ice, pebble ??) stuck between the brake caliper and rotor. I removed the left front wheel and cleaned and inspected everything visible, but found nothing. I then had the wife slowly drive the car forward as I listened while standing near the driver’s side of the car. The sound seemed to be coming from, or near the center of the car. The next day she told me the squeak had gone silent. I then drove it and noticed a slight vibration on normal take off that is much more severe when making a slow left or right hand turn. Nothing at normal 40+ mph driving speeds. A bearing ????? Thank you
