Ball Joint

General Specifications:

NOTE: In order to obtain an accurate measurement, the dial indicator should be aligned as close as possible with the vertical axis (center line) of the ball joint.

To measure ball Joint deflection, attach a suitable dial indicator with a flexible arm between the lower control arm and the wheel knuckle or ball Joint stud.

Measure the ball Joint deflection while pushing tip and pulling down on the lower control arm, by hand.
^ If the deflection exceeds the specification, a new ball Joint must be installed.
^ If the deflection meets the specification, no further action is required.
