Servicing DT Swiss 240 FRONT hub this is my first post here. How can I service a DT swiss 240 front hub, as in remove the adapter ( end cap ) to get to the insides? Do i need a special tool? Does it even need servicing? There is plenty of info out there on how to service the rear hub and I have already done that but I can't find anything on servicing the front hub. Please help.
The DT Swiss 240s front hub is a sealed bearing hub.  Service includes removing the endcaps, removing the bearing seals, regreasing the bearing cartridge, and then reversing the process. 

There are no special tools required.  The end caps are a friction fit, and, while they are tight, they will remove by hand.

If bearings are damaged, replace the entire cartridge. 

This does require special tools. Or at least, strongly recommend them.:)

One last thing:  If there is nothing wrong with the hub, no service is required.
