My wife's Malibu exhibits an occasional "whine" coming from the right front while driving. Seems to come on mostly when turning right but has done it just going straight. Does not increase or decrease with engine speed. I cant reproduce the sound when I want to under the hood.
My guess is a power steering or alternator noise but it sounds fine sitting still and only occassionally going down the read.
How can i diagnose this? Any helo is appreciated!
