Mueller-Kueps released a Vibro-Impact bell-shaped separator designed to help save time removing suspension joints while still on the car. The Vibro-Impact separator reduces the amount of force needed to remove the joint and does not damage the ball joint boot in the process. The spindle is impact proofed so that the force of the impact will strike the joint and not the tool. The tip of the spindle has a ball bearing to reduce friction and to eliminate some of the work required when removing suspension joints.
