Step 1. With the small wrench loosen the nut under the adjustment knob. Be sure to lift up lightly on the knob and slide the wrench underneath. The nut loosens in the normal fashion (counter-clockwise). The knob and nut are removed as one piece. Do not try to separate.
Step 2. With the nut and adjustment knob removed, slide the 17mm socket over the nut on the shock and insert the 5mm allen key. Remove the nut and threadlock the threads. Reinstall and tighten. You will be able to tighten it by hand to sufficient tq.
Step 3. When you reinstall the nut/adjustment knob, use a small amount of threadlock on the threads of the OUTSIDE of the shock, and screw down the nut. You ONLY TQ THE ADJUSTMENT KNOB/NUT TO LIGHT PRESSURE. Maybe 3-5lbs. If that. Turn it till you feel light tension and stop. Too much pressure and the adjustment knob wont work correctly.
