When should all wheel studs be replaced?

The recommendation to replace all wheel studs when indicated by the vehicle manufacturer is based on the importance of adhering to the specific guidelines provided by the vehicle's design and safety standards. Vehicle manufacturers conduct rigorous testing and derive conclusions regarding the longevity and safety of their components, including wheel studs.

Replacing all wheel studs as directed ensures that they maintain structural integrity, proper load distribution, and safe vehicle operation. Manufacturer guidelines may take into account various factors such as the type of materials used, the application of forces during regular use, and the lifespan of the components under different conditions.

While replacing only a damaged or cracked stud may seem practical, it could lead to a situation where the remaining studs are compromised or do not match in strength, which could affect the performance and safety of the vehicle. Thus, following the manufacturer's advice provides a comprehensive and safety-focused approach to maintenance.
