Ball Joint: Testing and Inspection
Ball Joint, Upper
Checking Upper Ball Joint For Wear
1.
Raise car on floor jacks placed beneath lower control arms.
2.
Grasp lower edge of tire and move wheel in and out.
3.
As wheel is being moved in and out, observe upper end of spindle and upper arm.
4.
Any movement between upper end of spindle and upper arm indicates ball joint wear and loss of preload. If any such movement is observed,
replace upper ball joint.
NOTE: During the foregoing check, lower ball joint will be unloaded and may move. Disregard all such movement of lower ball joint. Also, do
not mistake loose wheel bearings for a worn ball joint.
