When do you need to replace a wheel bearing hub?
But, if the tone ring is corroded or damaged, it must be replaced.

But nothing is perfect, and when moisture seeps into the hub, it corrodes the tone ring.
What causes a wheel hub to back off?
Cause: Loss of bearing retention is the leading cause of hub bearing damage, resulting in wheel vibration and/or noise. The axle-retaining nut backs off when bearings demonstrate improper torque or have lost their self-retention features. This changes the setting of the bearings inside the hub, causing misalignment and accelerating wear.
