FAQs

Q1: Why does my hub make a metallic clicking sound that speeds up with vehicle speed?
A: This is typically caused by brinelling — small indentations in the bearing raceway from impact damage. As the rollers pass over each indentation during rotation, they produce a distinct clicking sound that increases in frequency with speed.

Q2: Why does my new hub have a small rubber seal around the ABS wire entry point?
A: This seal prevents water, dust, and road salt from entering the wire housing where it connects to the hub body. It helps protect the internal wiring from corrosion and environmental damage.

Q3: Can I use a hammer to seat the axle nut during installation?
A: No. Hammering the axle nut can damage the bearing internals and make it impossible to achieve the correct preload. Always use a torque wrench to tighten the nut to the manufacturer's specification.
