How to judge the wear of the ball head

1. You can feel whether the ball head is worn by turning the steering wheel; the amount of freedom of the steering wheel is generally within 15 degrees. If it exceeds this range and the steering rod moves but the horns do not move, this means that the steering ball head is worn.

2. Lift the car so that the wheels are off the ground, and drag the tires up and down. The tires can be easily dragged up and down, indicating that the ball head is large. If the above situation occurs, the ball head needs to be replaced as soon as possible to avoid driving hazards.
