I'm assuming a press is mentioned to reinstall the bearing ? Removing the axle is easy-it's just the bolt and the nut once you remove the bolt holding the top of the shock to it's mount, then remove entire assembly from the skid. The wheel is just press fit over the bearing and retained by a circlip. Once the circlip is removed I just tapped around the rubber wheel and worked it down. You need a bearing puller to remove the bearing though and once removed, the axle slides right out of the shock. To put the bearing back in place, i used a section of pvc pipe and slid that over the bearing and easily tapped it down into it's spot. Then put the rubber wheel back on by tapping it with a rubber mallet. Prior to that I took some calipers to measure the distance from the end of the axle to the bearing face so I'd know how far to tap it down. To me the huge pain in the ass was putting the axle back in place. The original one went in the new spot easily but the new one (with shock) was a pain which was partly because I was sitting on the floor so not much leverage. Maybe the new axle was a few thou longer but it did not want to go into place but with some creative use of a tie down strap, I was able to line it up.
