FAQs

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

A: Over-torquing crushes the bearing internals, setting excessive preload. This causes premature wear, increased heat buildup, and significantly reduces the bearing's service life.

Q2: Why does my new hub make a brief whining sound during the first few miles?

A: New bearings often have a break-in period where the internal components seat together. A mild whining that diminishes after 50-100 miles is normal. If it persists or worsens, have it inspected.

Q3: Can road debris damage a hub bearing?

A: Yes. Rocks, gravel, and road debris can strike the hub housing or damage the ABS sensor wire. In severe cases, impact damage can crack the bearing raceway or bend the sensor bracket.
