what are the symptoms/signs of bad front wheel bearings? I have a whining /humming noise from the front from 50-80 mph. I have eiback dampers 1 & 1/4 drop with Hotchkis springs and sway bar. I'm running 255 45 20 Toyo Proxes 4s on Milano wheels. Could the struts be causing the constant road noise. How would I know if the bearings need replacing?
