If the linkage isn't broke and nothing else is broke or cracked I will bet that you need to take apart all points that pivot and clean and grease them well. My friend had the same exact sypmtoms and that was the fix. Now he hits the zirks every couple of rides. When this first started to happen he thought the shock was shot too. He bought a clicker and stiffer torsion springs. We put them on, put it back together and it still did the same thing. We took the entire skid apart and discovered that the grease was dried up/gone, a couple of the shafts where pitted, and the bushings where shot. He cleaned up the shafts, put in new bushings, greased it well and back to new... When you do this you can inspect the linkage well. His started to crack about 1500 miles after he discovered the lack of grease deal binding the skid so at about 3000 miles. He pounds his phazer so I am amazed at the guys that seem to be able to break their linkages every other ride!
