| FAQ - Answer 1 | Yes. Replacing ball joints is not part of routine maintenance. However, they should be checked according to the manufacturer scheduled maintenance or mileage intervals, or at every oil and filter service. Most ball joints on later vehicles are sealed and do not require any grease. There are still some ball joints that should be greased every time the oil and filter is changed. Check your vehicle application for the correct service required. |
| FAQ - Answer 2 | Yes. It may change the alignment angles. Have the alignment checked after replacing any steering components. |

| Good Maintenance Practices - Section 1 - Bullet 1 | Inspect or have your ball joints inspected for signs of wear. 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. If you choose to replace a ball joint, you should consider replacing ball joints as a set to make front end alignment easier. |
| 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. |
