1 Insert a long punch (with a good square edge) into the center of the aluminum wheel bearing spacers and push up against the inner edge of the spacer on the opposite side of the wheel (Fig. 1). 2 Using a hammer, tap the punch around the entire circumference of the spacer until it completely slides out of the bearing (Fig. 2). Turn the wheel over and remove the other spacer in the same way. 3 Use a long screwdriver or narrow pry bar and pry the seals out of each side of the wheel (Fig. 3). 4 Using snap ring pliers, remove the bearing retaining snap ring from either the disc or sprocket side of the wheel (Fig. 4). 5 Insert a long punch (with a good square edge) into the center of the wheel bearing, and push up against the inner edge of the bearing on the opposite side of the wheel. Using a hammer, tap the punch around the entire circumference of the bearing until it completely slides out of the hub. Turn the wheel over and remove the other bearing in the same way. NOTE: It may be necessary to tap on the punch sideways at first to knock the center aluminum sleeve off center so that you are able to get the punch on the edge of the bearing. 6 Clean areas where bearings will be inserted back into hub and apply a thin coat of grease around the machined hub surface. Tap the bearing on the snap ring side of the hub into the machined hub surface, making sure to keep it square with the hub as it goes in and only tap on the outer race of the bearing. Once you get the bearing flush with the outer edge of the hub, use a socket or piece of pipe that is just smaller than the outside diameter of the bearing to finish tapping the bearing into the hub.
