  2. Clamp the shock absorber in a vise horizontally with the shock absorber rod (1) completely extended.
  3. Drill a hole in the shock absorber at the center punch (4) using a 5 mm (3/16 in) drill bit. Gas or a gas/oil mixture will exhaust when the drill bit penetrates the shock absorber. Use shop towels in order to contain the escaping oil.
  4. Make an indentation in the middle (2) of the tube (3) with a center punch.
  5. Drill a second hole in the shock absorber at the center punch (2) using a 5 mm (3/16 in) drill bit. Oil will exhaust when the drill bit penetrates the shock absorber. Use shop towels in order to contain the escaping oil.
  6. Remove the shock absorber from the vise. Hold the shock absorber over a drain pan horizontally with the holes down. Move the rod (1) in and out of the tube (3) to completely drain the oil from the shock absorber.
