-----You don;t say how many miles you have on the car, but wheel bearings going bad within two years of driving suggests either an installation problem or poor bearings. Without seeing how they were installed (did the guy on the press force them in by using the inner race?) it's impossible to guess.
-----And, I have to ask, are you sure it isn;t the rear bearings going this time?
About 85K. not sure about the installation process, that is did he force them using the inner race. I'm pretty sure it's the front . Since it's happen quite often with this car, I've gotten accustomed to the presence / location of the sound.
