Wear indicator load carrying ball joints should be inspected with the ball joints loaded.

Wear indicators on load-carrying ball joints are designed to reveal wear only when the joint is under the vehicle’s normal load. When the car sits on the tires, the suspension compresses and the joint carries weight, causing any wear to show in the indicator. If you inspect with the ball joints unloaded (jacked up, wheels off ground, no weight), the indicator may not reveal wear even if the joint is worn. So the correct approach is to inspect with the ball joints loaded, meaning with the vehicle weight on the suspension. This ensures the wear indicator reflects the joint’s condition under real operating forces. Lubrication status isn’t the factor here, and inspecting with no weight can lead to a false sense of safety.
