Front seal area maintenance
A front stub axle slinger protects the seal area from the mud and muck that gets thrown up by the tire. It keeps that debris from collecting against the seal and working its way into the bearing grease. The part is small, but it does a steady job every time the vehicle runs in wet or dirty conditions.
Maintenance is mostly visual. Check that the slinger is seated correctly, not bent, and free of packed mud. When the hub or brake components come off, clean the area and look at the seal lip for hardening or wear. Dana 30 front axles often run in rough conditions, so a damaged slinger is worth replacing early instead of waiting for the seal to fail.
