When should ball joints with wear indicators be checked?

Ball joints with wear indicators should be checked when loaded and by visual observation because this provides the most accurate assessment of their condition. When the suspension system is under load, it simulates the actual working conditions that the ball joints experience while driving. The wear indicators are designed to help visualize any excessive wear that may affect the performance and safety of the vehicle. Observing them in this loaded state allows a technician to detect any play, cracks, or other signs of wear that might not be visible when the vehicle is lifted or unloaded.

Additionally, checking them visually while the vehicle is loaded ensures that the technician can assess how they function in real-world conditions, giving a better understanding of whether replacement or adjustment is needed. This practical approach to inspection is crucial for maintaining proper suspension and steering performance, ultimately contributing to the safety and reliability of the vehicle while on the road.
