2005 Buick Century Shock Absorber

You need to clamp the strut in a vise horizontally with the rod completely extended and drill a hole in the strut at the center of the end cap using a 5 mm (3/16 inch) drill bit. Gas or a gas/oil mixture will exhaust when the drill bit penetrates the strut. Then use shop towels to contain the escaping oil, remove the strut from the vise, hold the strut over a drain pan vertically with the hole down and move the rod in and out of the tube to completely drain the oil from the strut.

The recommended torque is 85 Nm (63 ft. lbs.).

You need to install the coil spring and upper strut mount to the J 45400, turn the spring compressor forcing screw until the coil spring is compressed, install the strut to the coil spring and upper strut mount and the strut retaining nut, and use the J 42991 and a 45 TORX socket to install the strut mount nut, remove the strut from the J 45400 and install the strut to the vehicle.

You need to install the strut, the strut upper nuts, and the strut lower bolts and nuts, align the strut to the mark on the knuckle, install the tire and wheel, lower the vehicle and align the front wheels.
