I drove the whole Tail of the Dragon SEC event with a wheel bearing making a droning roar at about 60 mph. By the time I replaced it there were a fair amount of shavings from the one siezed roller. Since I replaced and repacked the wheel bearings, the noise and twitch-shake I thouht was alaignment related had gone away! So if you got yhe shakes, you might want to examine those wheel berings.
