Hi. I have a 2002 Pontiac Bonneville.
There is a whining noise when I make a turn (right or left) and accelerating (pressing the gas pedal). This noise sounds similar to noise in low gear from a car with a bad gearbox in the old days.

If I turn but let the car coast, or when I am braking, then there is no noise.

Does anyone know what the problem is and if it should be fixed immediately?
Thanks a lot. :roll:

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Provide any existing inspection findings and clarify where the noise was heard during the previously reported episodes.

Guidance references and applicability

Source: Original question and visible replies. Owner reports and other participants' experiences are distinguished. Next steps are editorial requests for clarification or existing diagnostic findings, not a verified repair procedure or an independently confirmed component diagnosis.

CV joint? But hard to believe it would go bad on 2002 unless you have high miles or a broken CV boot to let dirt and water in.
