FAQs

Q1: Can a hub bearing cause my vehicle to make a clicking noise when accelerating?

A: Hub bearings typically produce humming or growling sounds. Clicking during acceleration is more commonly caused by worn CV joints, especially on FWD vehicles.

Q2: Why is there a thin layer of grease on the new hub's mounting surface?

A: This prevents corrosion between the hub and knuckle during storage. During installation, wipe it clean and apply a very thin coat of anti-seize if recommended by the manufacturer.

Q3: Can I replace a hub assembly myself to save money?

A: Yes, if you have the proper tools including a torque wrench, jack stands, and possibly a hub puller. However, improper installation can lead to premature failure or safety issues.
