When the compoonents are tightened against their "natural" position of a loaded suspension, and then forced into the loaded suspension, the rubber must stretch into this new position. Therefore, the ruuber is essentially ALWAYS under stress and wears out prematurely. My theory is that the rubber is not stretching ALL the way and my ride is higher than it should be. I'm hoping to find out that YES, this is what's going on, before I spend money on an alignment after doing what joe p suggests. Furthermore, if the rubber has been stretched for 60Kmi then maybe I should just pony up the money for new links in rear , yuk yuk and then get an alignment...
