Installing our aluminum Ultra Axles requires special attention. This video gives some guidance on the installation and removal of these axles. Start threading by hand and then using a good quality skate tool like the Sonic Tool shown here, be sure to torque no more than 1/8th turn. If you over-tighten these axles the high friction that develops between the two aluminum parts can result in difficulty removing them. When you do remove the axles it’s normal to hear a pop or screech sound. Always check the tightness of your axles every time you skate.
