A: Ball joint, tie rod end and the dust cover should be inspected for 80,000 km. The upper and lower control arm, ball joints and the dust cover should be inspected for 80,000 km and replaced if necessary. The tie rod end of the vehicle is similar to the joints of the human body and is often in a rotating state and it needs to be well lubricated. Because it is wrapped in a cage, if the grease deteriorates or is damaged, the ball joint will be loose inside the cage.
