What size wrench do I need for the rear hub on my Schwinn cruiser? It is a Shimano Type D. Also, what grease is recommended that I might be able to by locally. Thanks to all.
You probably need a 15mm cone wrench and a 17mm regular wrench. If you're going to buy a cone wrench, the 13/15mm double-ended wrench covers most hubs.
I recommend any PTFE-based bearing lubricant. You can buy a huge tub of it from an automotive store for very cheap.
