Prior to inspecting ball joints, ensure wheel bearings are properly adjusted.
1.
Raise vehicle and position stands under right and left lower control arms near each lower ball joint. Vehicle should not rock while on stands and
the upper control arm bumper must not contact frame.
2.
Clean and inspect ball joint seals for cuts or tears. If seal is cut or torn, the ball joint must be replaced.
3.
Position dial indicator against the lowest outboard point on the wheel rim, Fig. 17.
4.
Rock the wheel in and out and observe gauge. Horizontal deflection should not exceed .125 inch.

If reading exceeds specification, or if ball stud had been disconnected from knuckle assembly and any looseness is evident, or if stud can be turned
by hand, replace ball joint.
