It fits between the axle spindle and the wheel hub to prevent lubricant leaks and protect the bearings from contamination. A failed seal can lead to bearing failure and wheel-end damage, so this part is typically replaced whenever brake or bearing service is performed. The 'Old Bearing Combo' description suggests it may be associated with legacy or specific bearing sets commonly used on older trailer axles.
