The most common suspension issues in cars include worn out shocks and struts, damaged bushings, loose or worn ball joints, and broken or worn control arms.

To address these issues, the specific faulty parts should be identified and replaced. Worn shocks and struts should be replaced with new ones, damaged bushings should also be replaced, and loose or worn ball joints should be replaced. Broken or worn control arms should also be replaced. It's important to have the suspension system inspected and repaired by a qualified mechanic to ensure it's properly diagnosed and repaired.
