It protects your wheel bearings and axle spindle from contamination, which is critical for preventing premature bearing failure and expensive roadside breakdowns. You typically replace this seal any time the hub is pulled for brake work, bearing service, or if you notice oil leaking from the hub onto the inner tire or brake shoes. It uses a high-temperature elastomer and a durable sealing lip design to handle the heat, load, and harsh conditions of commercial truck drive axles.
