1. Can 105, Ultegra freehubs(freewheels) be disassembled, cleaned and repacked with grease and if so, which tools are used and how is it accomplished?
2. Can we use a Ultegra freehub on a 105 hub?
3. Why do Shimano freehubs have so much extra bearing 'play' and what is considered excessive?
4. How long do 105/Ultegra freehubs last?
Thanks in advance
ps. Take a look at the pic and notice the unusual retaining nut: http://www.jensonusa.com/store/produ...ehub+Body.aspx
