Wrap the body in a cloth. Invert the body, pointing the metal shank down. Use a pair of channel locks or regular pliers and gently compress the front and back surfaces about a half inch above the base, allowing the sides to separate (forming an oval). At the same time, press the metal shank down against a stable wooden base, allowing the inner mechanism to slide out of the body. If the inner mechanism seems stuck, put a little more pressure on the pliers, as there are two small locking tabs on the sides that keep the mechanism in and may be restricting its movement.

If the toothbrush has recently started making significantly increased noise during operation and the metal shank seems loose, the screw holding the shank to the motor shaft has probably backed out. When the inner mechanism has started to slide out of the plastic body, release pressure on the pliers and carefully remove the mechanism. A small screw and a triangular-appearing metal weight will probably come out with it. If not they have most likely fallen out the the hole left when the rubber sleeve cleared the body or they're still inside the plastic body. Once these parts are in hand, put the screw through the weight and with a pair of tweezers, return it to position shown in the illustration above and tighten the screw, reconnecting the shank to the motor shaft, using a 1/8" precision screwdriver. A thread locker may be used.
