My rear hub is loose and I'm not sure exactly how to tighten it. I have a pdf of a DT swiss manual that might be the same as my hubs, but it requires some pretty serious special tools. Can I just tighten it with a cone wrench somehow or am I going to have to take it to a shop? I haven't taken any of my bikes to a shop in nearly 6 years, so I'm not excited about doing that again. On the other hand, I don't think I want to invest in a complete set of expensive tools just to service my hub. Hmmm...

Ideas?
