FAQs

Q1: Is it necessary to use thread locker on the hub bolts?

A: Check your service manual. Some manufacturers require blue thread locker on the knuckle-to-hub bolts to prevent them from backing out due to vibration, while others rely on specific torque specs alone.

Q2: Can I drive with a humming noise coming from the wheel?

A: You should not drive long distances. A humming or growling noise usually indicates bearing failure. If it seizes while driving, you could lose control of the wheel or damage the axle and brake components.

Q3: Does the new hub come with pre-applied grease?

A: Yes. Modern hub assemblies are sealed units packed with high-temperature grease at the factory. Never try to add more grease through a seal, as this will damage the internal components.
