I used a regular flathead screwdriver to loosen the c-clips on the old shock absorbers and immediately pulled them out. The new ones immediately got up with a little bump, and now the hood of my wife's Volvo XC 90 doesn't fall on my head! Now the hood, which is tilted forward, slowly rises on its own. The main difference from the old, worn-out one! For the price, the dealer should have just swapped them out.
