FAQs

Q1: Why should an aftermarket hub be matched to the original generation rather than “upgraded” freely?

A: First-, second-, and third-generation hubs differ in flange design, preload method, and sensor integration. Using the wrong generation can create fitment, ABS, or safety issues.

Q2: Why is encoder compatibility more critical on modern vehicles than on older ones?

A: Newer ABS, ESC, and ADAS systems depend on precise wheel-speed signals. An incompatible encoder may cause intermittent warnings even if the bearing rotates smoothly.

Q3: Why should suppliers keep packaging and batch records for hub units?

A: Packaging protects seals and encoders during transport, while batch records support traceability if a quality issue appears later in the field.
