Suspension Strut Disposal
WARNING: This page is about a different car, the 2002 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
Clamp the strut in a vise horizontally with the rod (1) completely extended. See Fig 1. Drill a hole in the strut at the center of the end cap (3) using a 5 mm (3/16 in) drill bit. Gas or a gas/oil mixture will exhaust when the drill bit penetrates the strut. Use shop towels in order to contain the escaping oil. Remove the strut from the vise. Hold the strut over a drain pan vertically with the hole down. Move the rod (1) in and out of the tube (2) to completely drain the oil from the strut. See Fig 1.
