Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to help with this today.I apologize for any delay.
If this is an all wheel drive model here and the front wheel bearings were replaced to try and correct this issue the other component that will cause this is the front differential output shaft bearings that the axle shafts ride on.These bearings tend to wear in the differential and cause this here.In this case the differential would most likely need removed and inspected internally to pinpoint if one is at fault needing replaced as well as for any other damage in it needing repaired.This would be part number 11 in the diagram here.https://www.dropbox.com/s/12afiggty897l2b/ax-10-30.gif?dl=0
Even though the wheel bearings were replaced if this noise did not occur until 7000 miles after they were replaced there is a chance (and a good chance) that one of the wheel bearings has failed prematurely.Usually when you turn side to side if the noise gets louder one way and quieter the other way this indicates a failed wheel bearing needing replaced.This may be a part that is covered under parts warranty at the facility that did the replacement.If you turn right this shifts the weight to the left side and if it gets quieter this indicates the right front wheel bearing needs replaced.If it gets louder this indicates the left front wheel bearing needs replaced.
