    Q:
    How should one safely handle gas charged shock absorbers during maintenance on GMC Canyon? Posted by Customer
    A:
    The snap ring within your gas charged shock absorber tube contains high pressure gas so removing it poses a safety risk of severe gas expulsion. Safety glasses and caution toward the shock absorber tube should be used to prevent injuries when performing spot drilling and center punching activities. A centerpunch should create a 10 mm (0.4 in) long indentation at the tube bottom prior to processing. Place the shock absorber inside a vise with its rod extended while keeping it horizontal position. Drill a 5 mm (3/16 in) hole at the centerpunch location while exhaust gas with potential oil mixture escapes through shop towels for containment. The second hole needs drilling at the middle centerpunch indentation using a 5 mm (3/16 in) bit to drain the shock absorber oil while shop towels protect against eventual liquid spillage. After releasing the shock absorber from the vise angle it with drain holes facing down and insert the shaft to pull out all remaining fluid from the tube.
