Front Shock Absorber Disposal

WARNING: This page is about a different car, the 2016 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

Whenever drilling into a front shock absorber, wear protective eye wear. The gas in the shock absorber is pressurized and could spray metal filings into the eye.

Place the front shock absorber on a level surface or with the piston pointing downwards.
Drill a 2-3 mm {0.08-0.11 in} hole at the point 10 mm {0.39 in} from the lower end of the tube so that the gas can escape.

Turn the hole made in Step 2 downwards and drain the oil by pumping the piston rod up and down several times.
Cut off the bottom end of the front shock absorber.
Dispose of waste oil according to local waste disposal laws.
