7. Inspect the ball joint for relative movement by alternately pulling downward and pushing upward on the upper arm by hand. Note any relative
movement between the wheel knuckle and upper arm at the upper ball joint.
^
If relative movement is not felt or seen, the ball joint is OK. Do not install a new ball joint.
^
If relative movement is found, continue with Step 8.
Note:
^
In order to obtain an accurate measurement, the dial indicator should be aligned as close as possible with the center line of the ball joint.
8. To measure ball joint deflection, attach a suitable dial indicator with a flexible arm between the upper arm and the wheel knuckle or ball joint stud.
9. Measure the ball joint deflection while an assistant pushes upward and then pulls down on the upper arm, by hand.
^
If the deflection exceeds the specification, a new upper ball joint must be installed.
^
If the deflection meets the specification, no further action is required.
