If you hear a knocking noise when driving your Audi A3 over bumps, start by checking for a loose spare tire or jack. If the issue persists, it could be due to a worn-out bushing, suspension ball and joint problem, or suspension shock/strut issue. It's essential to have your suspension inspected and repaired promptly. A leaking lubricant or worn-out boot may indicate a ball and joint problem, while a bumpy ride could signal an issue with the suspension shock or strut. Replacing the ball and joint typically costs between $340 and $450, while a strut replacement averages between $1000 and $1110.
