When the car stops, there is a certain gap between turning the steering wheel left and right. The technical term is free travel. Every car has a standard data in degrees, which is the matching clearance of steering gear, steering gear and steering wheel.

When the free travel exceeds the standard data (becomes larger), it is generally the internal wear of the steering gear and steering gear, which can be adjusted by adjusting screws or adding or subtracting gaskets.

Other parts, such as the worn connecting ball head, can only be replaced.

Extended data:

The steering wheel is generally connected with the steering shaft through splines, and its function is to convert the force that the driver acts on the edge of the steering wheel into torque, and then transmit it to the steering shaft. When steering with a steering wheel with a larger diameter, the driver's hand force acting on the steering wheel is smaller.

As the connecting piece between the steering gear and the steering shaft, the steering transmission shaft is beneficial to the generalization of the steering gear, compensates the errors in the manufacturing and installation process, and makes the installation of the steering gear and the steering wheel more reasonable.
