FAQs

Q1: Why does a failing hub bearing get hotter than a healthy one?

A: Internal damage increases friction between rollers, raceways, and seals. The extra friction generates heat that can be felt at the wheel center after driving.

Q2: Why can repeated hard braking shorten hub bearing life?

A: Brake heat transfers into the hub and bearing. Excessive temperature can soften grease, weaken seals, and reduce bearing hardness over time.

Q3: Why should a hot hub not be cooled with water immediately after driving?

A: Rapid cooling can distort the hub flange, damage seals, or create micro-cracks in hardened components. Allow the assembly to cool naturally before inspection.
