Wheel bearings are an integral part of the vehicle’s brakes and suspension, so you need to look at the overall condition of all three (brakes, bearings and suspension) when doing service work. It is also important to go for a test drive to confirm the customer’s complaint. Often, tire noise is mistaken for bearing noise. Check the technical service bulletins (TSB). Often an OEM will release a TSB regarding new procedures and tools for the wheel bearing replacement after a vehicle has been in the field.
