You say the CDs don't tell you how to remove the wiper assembly. They do; I just looked it up this weekend. They do NOT, as near as I can tell, tell you how to DISSASSEMBLE the unit. The instructions given in the link a few posts up are specific to a few models. Most monoblade wiper assemblies DON'T come apart with a couple well-placed dental pick probings. Mine, for example. It really needs to come off the car and be disassembled on the bench. I haven't tackled mine yet.
