If the assembly is not aligned after installation, the wheels may not turn accurately according to the steering wheel's instructions. This may cause the driver to feel that the steering is not sensitive, the steering wheel is tilted, or the vehicle is pulling away when driving in a straight line.

After replacement, the geometric relationship of the steering system may change due to possible size differences between the new and old parts or slight errors during installation. If calibration is not performed, these changes will cause problems in the operation of the steering system.
