Ball Joint
A ball joint is a crucial car part that connects the steering and suspension systems, working like a human hip joint. It allows wheels to move up and down while turning left and right. Auto technicians regularly check and replace ball joints because they're essential for safe driving and proper wheel alignment. When looking at resumes, you might see this term mentioned alongside steering repairs, suspension work, or front-end service. It's a fundamental skill for any automotive technician, similar to how brake service or tire rotation are basic services in auto repair.
