A wheel hub bearing is part of a vehicle steering system. The trademark of a bad wheel bearing on a Cadillac is a roaring noise. In addition it may make a grinding noise when making turns. Another symptom is that your car might pull to one side when the brakes are applied.
Things You'll Need
- Lug wrench
- Hydraulic jack
- 15mm socket
- Breaker bar
- 32mm socket on 1/2 inch drive

Remove lugs from the wheel by using the lug wrench. Take the lug wrench, placing it on the wheel lug, and turn counterclockwise until the lugs are removed. Raise your vehicle with the hydraulic jack until the tire is completely off the ground. Remove the tire.
