This invention is a unique mechanical combination devised to effect the rapid and efficient removal and replacement of the upper nut on the stem of the front shock-absorbers used in motor-vehicles. A round member, having a squared top, is scored in two places on the circumference thereof, which scores are adapted to receive and hold two snap-rings. The bottom part of the round member is relatively larger in exterior diameter than the body thereof and is interiorly oblongularly hollowed to fit over and to hold the stem of the shock-absorber. The round member with one snap-ring attached is adapted to be placed inside of and to move up and down in, a hollow cylindrical member for a distance governed by the position of the other snap-ring. The hollow cylindrical member has an exteriorly hexagonal hollow top section, the interior diameter of which is fractionally larger than the exterior diameter of the body of the round member and which holds the round member in movable working positions. The squared end of the round member, in place in the cylindrical member, is adapted to be held by a T-shaped handle, with an interiorly squared tail, by set-screw means in the tail of the handle. The cylindrical member has another section directly under the hexagonal top section, which is relatively larger in diameter than the top section. The bottom section of the cylindrical member is relatively smaller in exterior diameter than the diameter of the body of the cylindrical member and the bottom section is interiorly ridged to form an interior hexagon, designed to receive and hold the upper nut of a front shock-absorber.
