Dodge avenger 2008 when I hit a bump on the drivers side I here a squeaking noise what could it be?

The squeaking noise you're hearing when hitting a bump on the driver's side of your 2008 Dodge Avenger could be caused by worn suspension components, such as struts, shock absorbers, or bushings. It might also be related to loose or damaged parts in the suspension system, like sway bar links or control arms. Additionally, check for any debris or rust that could be causing friction. A thorough inspection by a mechanic would help identify the exact cause.
