Many people know how hard it is to change a hinge dust cover on a car, including how long it takes to do this procedure. It's about two hours! Not to mention the fact that it will require disassembling the entire car strut to remove the ball joint.. But recently, engineers have come up with a unique way to quickly replace the dust pieces of the ball joint on any car with the help of a new universal tool - a pneumatic puller of ball joints! Puller allows you to quickly and easily install the universal dust cover without removing the driveshaft from the car, disassembly of the ball joints is also not required. It allows you to install both dust covers - external, on the wheel side, and internal, on the gearbox side.
