To check for wear, support car with ball joints loaded. Clean off any dirt or grease on bottom of ball joint. There will be wear indicators protruding from the bottom of the joint. Measure the amount of indicator extended beyond the surface of the joint. If it is more than .047" your good, if less than that the joint is worn and needs to be replaced.
