So the time has come to do some important maintenance I have a bottom bracket creek. Sometimes it goes away for a while. It isn't very bad but hampers the enjoyment of the bike and can't be very good for it . I would like to do something about it myself . I don't have a bike stand or have I done this before .
what tools would I need ?
what is the procedure?
What grease do I need?
is repacking bearings part of it ?

Thank's
