Also, since locking hubs generally do not require a key to operate, they can be maliciously locked or unlocked by persons other than the vehicle owner. Retrieved from ” https: Other benefits also include keeping the front-differential free from unnecessary wear, quieter operation, less vibration, and lower wear in other drive line components.
