Shock Absorber Disposal
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Gas charged shock absorbers contain high pressure gas. Do not remove the snap ring from inside the top of the tube. If the snap ring is removed, the contents of the shock absorber will come out with extreme force which may result in personal injury.
WARNING:
To prevent personal injury, wear safety glasses when center punching and drilling the shock absorber. Use care not to puncture the shock absorber tube with the center punch.
- Make an indentation 10 mm (0.4 in) from the bottom (4) of the tube (3) using a center punch.
- Clamp the shock absorber in a vise horizontally with the shock absorber rod (1) completely extended.
- 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.
- Make an indentation in the middle (2) of the tube (3) with a center punch.
- 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.
- 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.
