Rear Shock Absorber Disposal

WARNING: This page is about a different car, the 2004 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Whenever drilling into a shock absorber, wear protective eye wear. The gas in the shock absorber is pressurized, and could spray metal chips into the eyes and face when drilling.

Clamp the shock absorber on a flat surface.
Drill a 2-3 mm (0.08-0.12 in) hole at a point 25 mm (0.98 in) from the bottom of the tube, so that the gas can escape.

Turn the hole downwards.
The oil can be collected by moving the piston rod several times up and down and cutting the tube at the end.
Dispose of waste oil according to local waste disposal law.
