Ball joint, front axle, left=right for Porsche 964

The ball joint ensures the connection from the wheel carrier to the wishbone and transfers the wheel loads that occur to the cross member. In many cases, the ball joint's rubber boot fails due to dynamic loading and material embrittlement, allowing dirt and water to enter the ball joint. Therefore, ball joints should be regularly inspected for play in the joint. The ball joints should always be changed by axis. You should definitely not continue driving with a defective ball joint, because in the worst case the ball head can come loose from the joint socket. As a result, the guidance of the wheel is no longer guaranteed and it can deflect unpredictably.
