The IIRC rebound adjuster "know" (the one on the body of the shock by the "top" eye" is dead. No clicks.
Took the eye off and found that the small shaft inside the real shaft that normally acts like there is a spring behind it simple drops down into the bottom position. What could the cause be. Shock has gas pressure. Also pushing the shock into compression will cause the interior rod to pop up but will drop back down at the slightest touch.
