I would check the end links for any excessively sharp burrs - if there are any I would stone them off to create a more rounded surface.
You ant as little movement between the end link and the case as possible, so for the style of end links that can be bent, making sure they are tight is a good idea. Also using the correct spring bar can prevent abnormal movement (a thinner bar can allow more movement).
