2. A vise with some form of padded jaw works well to hold the shock during much of the rebuild process. Disassembly started with loosening the small setscrew in the bearing cap and loosening the cap using a spanner wrench. Nitrogen pressure should be discharged from the shock before completely removing the bearing cap. Once the bearing cap was unscrewed and slid up the shock shaft, the exposed internal snap-ring could be removed from inside the shock body.
