How do you replace rear shocks for hatch?

Two different types, one is held on with clips and the other one screws in. Support the hatch so you can work on it. At the end if there is a clip around the end of the shaft, it pulls off. The shock clips over or rides on a ball. The clip goes 3/4 of the way around the shaft of the shock and locks it to the ball.

If there is no clip, the ends screw out of the side of the hatch and the body. Probably use a 12 mm wrench on most of them. A few do have a mounting plate on the end that should have 2 bolts or screws. If you have the new one for your car, looking at the ends will tell you how to remove the old one.
