How should one safely drain oil from gas charged shock absorbers on Chevrolet Astro?

Do not take out the snap ring from inside the tube of gas charged shock absorbers because high-pressure contents will forcefully eject which could lead to serious injuries. Safety glasses should be worn throughout center punching and shock absorber drilling to reduce the risk of personal injury alongside keeping the tube from puncture. A 10 mm (0.4 inch) indentation should be created 10 mm (0.4 inch) from the tube's bottom edge using a center punch tool. Horizontal positioning of the shock absorber in a vise requires a complete extension of the shock absorber rod before clamping the unit. Use a 5 mm (3/16 inch) drill bit to create a hole at the center punch spot on the shock absorber to release either gas or its oil mixture. The process requires shop towels to catch leaking oil. Drill another hole at the center-punched mark of the tube while containing the oil discharge with shop towels. The shock absorber removal process ends by positioning the drain pan under the drain holes while using the rod to move inside the tube until all oil empties out from the shock.
