FAQs

Q1: What happens if I over-torque the axle nut?

A: Over-torquing crushes the internal bearing rollers and races, eliminating the necessary clearance. This creates extreme friction and heat, which will cause the new hub to fail very quickly. Always use a calibrated torque wrench.

Q2: How do I know if the noise is coming from the tire or the hub?

A: Tire noise usually sounds rhythmic and changes with the tread pattern. A failing hub produces a continuous humming or growling noise that increases in pitch and volume as vehicle speed increases, regardless of the road surface.

Q3: Can a worn hub assembly damage my CV axle?

A: Yes. If the hub has severe lateral play, the constant wobbling puts excessive stress on the CV axle splines and joints, potentially causing the axle to wear out or fail prematurely.
