[QUOTE="hmwave, post: 1976055, member: 10968"] Here's my thoughts on the failure mode. 1. The bushings were an extremely tight fit in my Strange shocks so I had to press them in while out of the car with a 3' breaker bar and heavy bolt and washers. I had to use enough force that I thought something would snap but it didn't. [B]Result[/B]: there's no way the bushings can rotate inside the shock eyelets. And the eyelet was already under 'splitting pressure' from the tight bushings. 2. The lower mounting bolt is torqued to 98lb/ft firmly locating the hard bushings against the two thin washers and LCA mounting face. [B]Result[/B]: the shock eye is likely to have zero to near zero rotational articulation around the LCA mounting bolt. 3. As the LCA articulates in normal driving the rotationally immovable shock shell is repeatedly rocked left to right along the driver-passenger axis of the car. In shocks with rubber bushings the rubber alternately gives as this occurs so allows a few degrees of rotation to accomodate the LCA movement. With the hard bushings bolted hard into and against the LCA the shock eyelet doesn't rotate so the rotational stress is transferred into the top of the shock eyelet. [B]Result[/B]: the eyelet is repeatedly stressed and the metal eventually fatigues and seperates. My shocks tore along the shell dimension that was receiving the majority of the 'rocking' stress, consistent with this failure mode theory. [/QUOTE]
