FAQs

Q1: Why does my hub bearing make a roaring noise that sounds like an airplane taking off?
A: Severely worn bearings can produce a loud roaring or rumbling sound similar to an aircraft engine. This indicates advanced internal damage and the bearing should be replaced immediately to avoid wheel seizure.

Q2: Why does my new hub have a small sticker with a barcode on it?
A: This sticker contains the part number, batch information, and traceability data for quality control purposes. Keep it intact until after installation in case you need to verify the correct part was received or process a return.

Q3: Can I install a hub assembly without removing the brake rotor?
A: On most vehicles, the brake rotor must be removed to access the hub mounting bolts or to properly inspect the mounting surface. Check your vehicle's specific service procedure before starting.
