Vegast and Aldhu might be difficult to mount when you don't own the proper tools.

We recommend to use a such wrench like Park Tool 62.

You need to apply a force of 3540nm on the centerbolt.

If the spider is still moving, you can try to dismount, mount again serveral times until it's locked. You may also add grease on the teeth of the spider/axle.
