What indicates that there is a gap that may point to an issue with the wheel assembly?

A gap between the nut and wheel is a critical indicator that there may be an issue with the wheel assembly. This gap can suggest that the wheel is not securely fastened to the hub, which raises concerns about the integrity and safety of the wheel. A properly installed wheel should have no gaps, as even a small separation can lead to the nut loosening further over time, resulting in potential wheel detachment while driving and significantly increasing the risk of an accident.

Monitoring the condition of the wheel assembly includes ensuring that all components are tightly secured and in proper alignment. Other indicators may suggest general wear or aesthetic issues but do not directly signal a functional problem with the wheel assembly itself.
