This is one of the hardest things I have tried to diagnose. I get a moan noise while turning slightly left at a certain angle to the left 50mph and up roughly. It moans when i turn slightly left. I had an alignment done a while back and that changed the angle a bit when it made the noise but its the same noise. Now I tried to rotate the tires to see if the tire was causing the noise but it seems to be the same. All the suspension up front is new and that did not cure the symptoms. Iv'e checked the wheel bearings and everything is tight and a shop said they were all ok. Other than the wheel bearing the only other thing I am thinking may cause the noise is the power steering or the rack. Could this cause these symptoms.? Also the gas pedal vibrates some at the same time the groaning happens. From what I can see nothing is rubbing and the noise has remained the same no changes in pitch or amount. Thanks in advance for any suggestions.
