Over time, lubrication inside the ball joint can dry out, leading to joint wear. Even sealed ball joints can be exposed to air, and if the ball joint's protective boot is damaged, dirt and debris could further harm the life and function of the joint. Exposure to harsh driving conditions like pot holes, bumpy road surfaces, or road salt may also cause ball joints to fail, and worn ball joints could result loss of vehicle control or tire damage. Inspect your ball joints regularly, following exposure to events that may harm the component, or when you experience signs of ball joint wear. Good Maintenance Practices - Section 1 - Bullet 2: Use new installation components. If you replace your vehicle's ball joints, make sure to use new mounting hardware, rather than reusing the old. Good Maintenance Practices - Section 1 - Bullet 3: Avoid replacing only one ball joint at a time.

Good Maintenance Practices - Section 1 - Bullet 4: Installing a new ball joint can interfere with the alignment of your vehicle. Perform a full four-wheel vehicle alignment after any ball joint replacement.
