Lug nuts keep coming loose on one wheel despite proper cleaning and torquing, presenting a safety risk.

Workarounds Described

• re-torquing lug nuts multiple times
• considering using Loctite as a fix

Implied Software Gaps

• Diagnostic software that systematically identifies causes of recurring lug nut loosening beyond torque

LugGuard Diagnostic

A mobile app that guides technicians through a structured diagnostic process for recurring wheel fastener issues. It logs torque specs, cleaning steps, and vehicle history to suggest the root cause (e.g., hub deformation, stud damage, or thread wear) and recommends the correct repair procedure, reducing trial-and-error and ensuring safety.
