yes, it pops up a bit without the springs. Mine has done what yours is doing but new shocks fixed it. At the time it was happening, and it was infrequently, the shocks would still hold the hatch up. The springs are not needed if the shocks are good but they add lift and are an added convenience when your hands are full.
