Front End Noise - Driving Straight On Smooth Roads
-
NOTE: Wheel hub bearings can produce noise after achieving 56 km/h (35 mph) while driving straight if they are worn.
- Front end noises while driving straight involve parts which rotate continuously while the road wheels are rotating. Typically not a steering gear.
- Noises can also be caused by loose or un-retained parts affected by wind.
Possible Source Action - Possible Rotating Sources:
- Axle shafts or halfshafts
- Carrier bearing (noise is typically felt through the console)
- Drive shafts
- Transfer case assembly (if equipped)
- Wheel hub and wheel bearings (typically higher speeds)
- Possible Wind Sources:
- Air dams
- Heat shields
- Radiator ducts or shields
- Wheel well splash shields
