Ball Joint

Ball Joint Deflection

Lower 0-0.8 mm (0-0.032 in)





Upper 0-0.2 mm (0-0.008 in)





Measure the ball joint deflection while an assistant pushes up and pulls down on the wheel and tire assembly, by hand.
^ If the deflection exceeds the specification, a new lower or upper ball joint must be installed.
^ If the deflection meets the specification, no further action is required.
