What is the correct process for installing the stub axle?
The silver sleeve has to be flush with the outside of the axle (2-55). You can silicone it into place so that it does not move when you slide the stub axle in to the 2-55. Slide the stub axle in until it is tight to the hub. Drill the sleeve and the stub axle by using the hole in the 2-55 as a guide. Drill only half way through the axle from one side and then drill the rest from the other side.
