FAQs
Q1: Why does a hub bearing sometimes fail without making much noise?
A: If the seal fails slowly, grease can leak out over time without immediate contamination. The bearing may lose lubrication gradually, causing increased temperature and internal wear before any audible symptom appears.
Q2: Why should grease never be injected into a sealed hub bearing?
A: Sealed units are packed with a specific type and amount of grease at the factory. Adding grease can overfill the cavity, increase internal pressure, damage the seal, and introduce incompatible lubricants.
Q3: Why does a hub feel hot after a short drive when the bearing is failing?
A: Increased friction from damaged rollers or raceways generates heat. A noticeably hot hub compared with the opposite side is a strong sign that the bearing is deteriorating internally.
