I agree with dotail and underfire. I would seriously consider changing all wheel bearings by 300K . Can they last longer then that... In certain conditions sure they can lost longer.. However, think of how many revolutions those wheel bearings did at 300K miles. If they are not going bad by then.. They will be on the way to failing.
