At highway speeds(60-75mph) I have a loud high pitched "hum". The sound drowns out around 80mph, and continues when accelerator is depressed. LTX Mich tires are in OK shape. Figuring its the wheel bearing(s), could it be other,i.e. driveline play, centerbearing?? I have the usual 80s thud upon accelerating, etc.etc. approx. 130k miles but well kept!
Any suggestions to look for before pulling the wheel apart and replacing bearings.
Thanks
